説明
Speed up your website by serving WebP images. By replacing files in standard JPEG, PNG and GIF formats with WebP format, you can save over a half of the page weight without losing quality.
When installing a plugin you do not have to do anything more. Your current images will be converted into a new format. Users will automatically receive new, much lighter images than the original ones.
As of today, nearly 90% of users use browsers that support the WebP format. The loading time of your website depends to a large extent on its weight. Now you can speed up it in a few seconds without much effort!
This will be a profit both for your users who will not have to download so much data, but also for a server that will be less loaded. Remember that a better optimized website also affects your Google ranking.
Support for additional directories
Now you can also convert files not only from /uploads
directory but also from /plugins
and /themes
directories. This allows full integration with the WebP format!
How does this work?
- By adding images to your Media Library, they are automatically converted and saved in a separate directory.
- If you have just installed the plugin, you can convert all existing images with one click.
- Converting to WebP format works for all image sizes. As WebP you will see all the images added to the Media Library.
- Images are converted using PHP
GD
orImagick
extension (you can modify the compression level). - When the browser tries to download an image file, the server verifies if it supports
image/webp
files and if the file exists. - If everything is OK, instead of the original image, the browser will receive its equivalent in WebP format.
- In default loading mode the plugin does not change image URLs, so there are no problems with saving the HTML code of website to the cache and time of its generation does not increase. It does not matter if the image display as an
img
HTML tag or you usebackground-image
. It works always! - The name of the loaded image does not contain the WebP extension. Only the source of the loaded file changes to a WebP file. As a result, you always have one URL to a file. Regardless of whether the browser supports WebP or not.
- Image URLs are modified using the module
mod_rewrite
on the server, i.e. the same, and thanks to this we can use friendly links in WordPress. Additionally, the MIME type of the sent file is modified toimage/webp
. - In case rewriting by rules from .htaccess file is blocked, a mode is available which loads images via PHP file. Then image URLs are changed, but the logic of operation is the same as in the case of the default mode.
- The final result is that your users download less than half of the data, and the website itself loads faster!
WebP images are the future!
Raise your website to a new level now! Install the plugin and enjoy the website that loads faster. Surely you and your users will appreciate it.

Please remember to include the answers for all 11 questions by adding a thread. It is much easier and accelerate the solution of your problem.
-
Error on plugin settings screen?
-
If you have an error on the plugin settings screen, first of all please read it carefully. They are displayed when there is a problem with the configuration of your server or website.
The messages are designed to reduce the number of support requests that are repeated. It saves your and our time. If you have information in the message that you should contact the administrator of your server, please do so.
When contacting the administrator, give him all the information available in the message. If you still cannot solve the problem, please contact us.
We want to solve as many similar problems as possible automatically. This eliminates the need to wait for our response and you can try to solve the problem alone. This is very important for us.
-
Error while converting?
-
You can get several types of errors when converting. First of all, carefully read their content. For the most part, you can solve this problem yourself. Try to do this or contact the server administrator.
If you get an error:
File "%s" does not exist. Please check file path.
means that the file_exists() function in PHP returnedfalse
using the file path given in the error message. Check this path and make sure it is correct.If you get an error:
File "%s" is unreadable. Please check file permissions.
means that the is_readable() function in PHP returnedfalse
using the file path given in the error message. Check the permissions for the file and the directory in which the file is located.If you get an error:
"%s" is not a valid image file.
means that the file is damaged in some way. Download the file to disk, save it again using any graphics program and add again to the page. If the error applies to individual images then you can ignore it – just the original images will load, not WebP.If you get an error:
"%s" converted to WebP is larger than original and has been deleted.
means the original image weighed less than WebP. This happens when images have been compressed before. Disable the “Automatic removal of WebP files larger than original” option in plugin settings to force always using WebP.In the case of the above problems, contacting the support forum will be useless. Unfortunately, we are unable to help you if your files are damaged. You have to fix it yourself. If you have previously used other tools that changed the original files and damaged them, you will do nothing more.
Remember that it happens that other plugins can cause problems with accessing files or the REST API. Please try to disable all other plugins and set the default theme to make sure that it is not one of them that causes these types of problems.
-
What are requirements of plugin?
-
Practically every hosting meets these requirements. You must use PHP at least 7.0 and have the
GD
orImagick
extension installed. The extension must supportWebP format
. If you have an error saying that the GD or Imagick library are not installed, but you have it installed then they are probably incorrectly configured and do not have WebP support.They are required native PHP extensions, used among others by WordPress to generate thumbnails. Your server must also have the modules
mod_mime
,mod_rewrite
andmod_expires
enabled.An example of the correct server configuration can be found here. Link to your current configuration can be found in the administration panel, on the management plugin page in the section “We are waiting for your message” (or using the URL path:
/wp-admin/options-general.php?page=webpc_admin_page&action=server
).Note the items marked in red. If the values marked in red do not appear in your case, it means that your server does not meet the technical requirements. Pay attention to the WebP Support value for the GD library and WEBP in the list of supported extensions for the Imagick library.
In a situation where your server does not meet the technical requirements, please contact your server Administrator. We are not able to help you. Please do not contact us about this matter, because this is a server configuration problem, not a plugin.
Also REST API must be enabled and work without additional restrictions. If you have a problem with it, please contact the Developer who created your website. He should easily find the issue with the REST API not working.
-
What are restrictions?
-
The size of the image is a limited. Its resolution cannot be bigger than
8192 x 8192px
. This is due to the limitations of the PHP library.Please remember that Safari (version 13 or earlier) and Internet Explorer do not support the WebP format. Therefore, using these browsers you will receive original images.
You can find more about WebP support by browsers here.
-
Damaged images on iOS or other browsers
-
The plugin in default loading mode (via .htaccess) uses rules in the .htaccess file to redirect from the original image to an image in WebP format. Verifies whether the WebP file exists and whether your browser supports the WebP format. It does this every time you try to load an image.
When you enter from a WebP supporting device, it will redirect. However, when someone uses a browser that does not support WebP, the redirection will not work and you get the original file.
However, if you see corrupted images on browsers that do not support WebP, it means that your server uses cache for rewrites from the .htaccess file. Then the plugin will not work properly because the server instead of reading the rules from the .htaccess file every time uses its cache and does the redirection automatically.
How can you check it? When you turn off the plugin, the rewrites from the .htaccess file are removed, which means you should see the original images on every browser. If this is not the case and you see forced redirects to WebP files, it means that your server remembers the redirects you made earlier and uses cache.
In this situation, please contact your server administrator. Each configuration is different. It can be e.g. module
mod_pagespeed
or other similar. This functionality must be turned off so that the server reads and executes the rules from the .htaccess file each time the images are loaded. This cannot be ignored because it will cause problems. -
What to do after installing plugin?
-
After installing the plugin, you should convert all existing images.
In the WordPress admin panel, on the
Settings -> WebP Converter
subpage there is a module that allows you to process all your images.It uses the WordPress REST API by downloading addresses of all images and converting all files gradually.
This process may take few or more than ten minutes depending on the number of files.
It should be done once after installing the plugin. New images from the Media Library will be converted automatically. For other images, e.g. from the /themes directory, you must start manual conversion after adding new images.
-
How to check if plugin works?
-
When you have installed plugin and converted all images, follow these steps:
- Run
Google Chrome
and enableDev Tools
(F12). - Go to the
Network
tab and select filtering forImg
(Images). - Refresh your website page.
- Check list of loaded images. Note
Type
column. - If value of
webp
is there, then everything works fine. - Remember that this plugin does not change URLs. This means that e.g. link will have path to .jpg file, but
.jpg.webp file will be loaded instead of original .jpg
. - In addition, you can check weight of website before and after using plugin. The difference will be huge!
- More information: here
Please remember that in default loading mode (via .htaccess) URLs will remain unchanged. When you open the image in a new tab or look at its URL, you’ll see the original URL. When you try to save the image to disk (e.g. by clicking Save as…) the original image will be saved.
WebP is only used when loading a image on a website. In default loading mode (via .htaccess) it is done by the rules from the .htaccess file, on the server side, without the visible URL change to the image. Yes, it can be called magic 🙂
That is why the plugin should be tested in Dev Tools. If the Type of file is
WebP
, then everything is working properly. You can also turn off the plugin for a moment and check the weight of your website, then turn it on and test again. The difference should be visible.The operation of the plugin for non-advanced users may sometimes be less understood, but everything is fine. Thanks to this, regardless of whether your browser supports WebP or not, everything works without problems.
Only images from the
/uploads
directory are automatically converted. If you use other plugins that also save images in the/uploads
directory then this may not work. Therefore, check the plugin settings and try converting all images again. - Run
-
Why are some images not in WebP?
-
If the converted image in WebP format is larger than the original, the browser will use the original file. This converted file will be deleted. Therefore, you can also see files other than WebP on the list. When this happens, you will receive information in debug.log.
If you want to force the use of WebP files, uncheck the
Automatic removal of WebP files larger than original
option in the plugin settings. Then click on theRegenerate All
button to convert all images again.Remember that this plugin supports images from the
/wp-content
directory, e.g. files downloaded from the Media Library. Redirections will not work if your images are downloaded from another domain, i.e. from an external service.When checking the operation of the plugin, e.g. in Dev Tools, pay attention to the path from which the files are downloaded and which directories you have enabled in the settings of plugin.
-
Where are converted images stored?
-
All WebP images are stored in the
/wp-content/uploads-webpc/
directory. Inside the directory there is the same structure as in the original/wp-content
directory. The files have original extensions in the name along with the new.webp
.In case the location of the original file is as follows:
/wp-content/uploads/2019/06/example.jpg
then its converted version will be in the following location:/wp-content/uploads-webpc/uploads/2019/06/example.jpg.webp
.In case the location of the original file is as follows:
/wp-content/themes/my-theme/public/img/example.jpg
then its converted version will be in the following location:/wp-content/uploads-webpc/themes/my-theme/public/img/example.jpg.webp
.Original images are not changed. If you remove plugins, only WebP files will be deleted. Your images are not changed in any way.
-
How to change path to uploads?
-
This is possible using the following types of filters to change default paths. It is a solution for advanced users. If you are not, please skip this question.
Path to the root installation directory of WordPress (
ABSPATH
by default):add_filter('webpc_site_root', function($path) { return ABSPATH; });
Path to
/uploads
directory (relative to the root directory):add_filter('webpc_dir_name', function($path, $directory) { if ($directory !== 'uploads') { return $path; } return 'wp-content/uploads'; }, 10, 2);
Directory path with converted WebP files (relative to the root directory):
add_filter('webpc_dir_name', function($path, $directory) { if ($directory !== 'webp') { return $path; } return 'wp-content/uploads-webpc'; }, 10, 2);
Note that the
/uploads-webpc
directory must be at the same nesting level as the/uploads
,/plugins
and/themes
directories.Prefix in URL of
/wp-content/
directory or equivalent (used in .htaccess):add_filter('webpc_uploads_prefix', function($prefix) { return '/'; });
For the following sample custom WordPress structure:
... ├── web ... ├── app │ ├── mu-plugins │ ├── plugins │ ├── themes │ └── uploads ├── wp-config.php ...
Use the following filters:
add_filter('webpc_site_root', function($path) { return 'C:/WAMP/www/project/webp'; // your valid path to root }); add_filter('webpc_dir_name', function($path, $directory) { if ($directory !== 'uploads') { return $path; } return 'app/uploads'; }, 10, 2); add_filter('webpc_dir_name', function($path, $directory) { if ($directory !== 'webp') { return $path; } return 'app/uploads-webpc'; }, 10, 2); add_filter('webpc_uploads_prefix', function($prefix) { return '/'; });
After setting the filters go to
Settings -> WebP Converter
in the admin panel and click theSave Changes
button..htaccess
files with appropriate rules should be created in the directories/uploads
and/uploads-webpc
. -
How to run manually conversion?
-
By default, all images are converted when you click on the
Regenerate All
button. In addition, conversion is automatic when you add new files to your Media Library.Remember that our plugin takes into account images generated by WordPress. There are many plugins that generate, for example, images of a different size or in a different version.
If you would like to integrate with your plugin, which generates images by yourself, you can do it. Our plugin provides the possibility of this type of integration. This works for all images in the
/wp-content
directory.It is a solution for advanced users. If you would like to integrate with another plugin, it’s best to contact the author of that plugin and give him information about the actions available in our plugin. This will help you find a solution faster.
You can automatically run the option to regenerate all new images. This is useful when you use external plugins that generate images themselves. To do this, use the following code:
do_action('webpc_regenerate_all', $paths);
Below is an example of how to use this action to automatically regenerate images after changing the theme:
add_action('init', function() { do_action('webpc_regenerate_all'); });
To manually start converting selected files, you can use the action to which you will pass an array with a list of paths (they must be absolute server paths):
do_action('webpc_convert_paths', $paths);
An alternative method is to manually start converting the selected attachment by passing the post ID from the Media Library. Remember to run this action after registering all image sizes (i.e. after running the
add_image_size
function):do_action('webpc_convert_attachment', $postId);
In addition, you can edit the list of files that will be converted. For example, to add some to the exceptions. To do this, use the following filter, which by default returns a list of all paths:
add_filter('webpc_files_paths', function($paths, $skipExists) { return $paths; }, 10, 2);
Argument
$paths
is array of absolute server paths and$skipExists
means whether to skip converted images.You can also modify the list of image paths for an attachment, e.g. to exclude one image size. To do this, use the following filter:
add_filter('webpc_attachment_paths', function($paths, $attachmentId) { return $paths; }, 10, 2);
Argument
$paths
is array of absolute server paths and$attachmentId
is the post ID of attachment, added to the Media Library.To delete manually converted files, use the following action, providing as an argument an array of absolute server paths to the files (this will delete manually converted files):
do_action('webpc_delete_paths', $paths);
-
How to change .htaccess rules?
-
Manually editing the rules in the .htaccess file is a task only for experienced developers. Remember that the wrong rules can cause your website to stop working.
Below is a list of filters that allow you to modify all rules. Remember that it’s best to use your own rule set rather than edit parts of exists. This will ensure greater failure-free after plugin update.
Returning an empty string will delete these rules the next time you save the plugin settings. You must do this after each filter edit.
Rules for redirects: (returns rules for
mod_rewrite
module):add_filter('webpc_htaccess_mod_rewrite', function($rules, $path) { return ''; }, 10, 2);
Argument
$path
is absolute server path for.htaccess
file (/wp-content/.htaccess
or/wp-content/uploads/.htaccess
).Rules for
image/webp
MIME type: (returns rules formod_mime
module):add_filter('webpc_htaccess_mod_mime', function($rules) { return ''; });
Rules for Browser Caching: (returns rules for
mod_expires
module):add_filter('webpc_htaccess_mod_expires', function($rules) { return ''; });
All rules from the files
/wp-content/.htaccess
,/wp-content/uploads/.htaccess
and/wp-content/uploads-webpc/.htaccess
: (returns rules for modules:mod_rewrite
,mod_mime
andmod_expires
):add_filter('webpc_htaccess_rules', function($rules, $path) { return ''; }, 10, 2);
Argument
$path
is absolute server path for.htaccess
file. -
What is Browser Caching?
-
This option allows you to speed up page loading time for returning users because they do not need to re-download files from the server. The plugin allows this by using the module
mod_expires
.It is enabled by default. If you do not want to use this functionality, you can turn it off at any time.
-
Does plugin support CDN?
-
Unfortunately not. This is due to the logic of the plugin’s operation. Plugins that enable integration with the CDN servers modify the HTML of the website, changing URLs for media files. This plugin does not modify URLs. Replacing URLs in the HTML code is not an optimal solution.
The main problem when changing URLs is cache. When we modify the image URL for WebP supporting browser, then use the browser without WebP support, it will still have the URL address of an image in .webp format, because it will be in the cache.
While in the case of the
img
tag you can solve this problem, in the case ofbackground-image
it is possible. We wanted full support so that all images would be supported – no matter how they are displayed on the website.Therefore in this plugin for browsers supporting the WebP format, only the source of the file is replaced by using the
mod_rewrite
module on the server. The URL for image remains the same. This solves the whole problem, but it is impossible to do when the files are stored on the CDN server.If you are using a CDN server, find one that automatically converts images to WebP format and properly sends the correct image format to the browser.
-
Configuration for Apache
-
In the case of Apache, when saving the settings, .htaccess files will be generated automatically in the following locations:
–/wp-content/.htaccess
–/wp-content/uploads/.htaccess
–/wp-content/uploads-webpc/.htaccess
If these files are missing or empty, try disabling and re-enabling the plugin or saving the plugin settings again. Also check the write permissions of the directories where these files are located.
If your server is a combination of Apache and Nginx, remember that the image files must be supported by Apache. Only then will the redirections in the .htaccess file work properly. Alternatively, you can use the configuration for Nginx.
-
Configuration for Nginx
-
Please edit the configuration file:
–/etc/nginx/mime.types
and add this code line:
types { # ... image/webp webp; }
Then find the configuration file in one of the paths (remember to select configuration file used by your vhost):
–/etc/nginx/sites-enabled/
–/etc/nginx/conf.d/
and add below code in this file (add these lines to very beginning of file if possible – if they will be at the bottom, other rules may block the rules for WebP from working):
server { location ~ /wp-content/(?<path>.+)\.(?<ext>jpe?g|png|gif)$ { if ($http_accept !~* "image/webp") { break; } add_header Vary Accept; expires 365d; try_files /wp-content/uploads-webpc/$path.$ext.webp $uri =404; } # ... }
After making changes, remember to restart the machine:
systemctl restart nginx
. -
Configuration for Multisite Network
-
Multisite Network mode works fine but requires adding configuration manually.
Please manually paste the following code at the beginning of .htaccess file in the
/wp-content
directory:# BEGIN WebP Converter # ! --- DO NOT EDIT PREVIOUS LINE --- ! <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{HTTP_ACCEPT} image/webp RewriteCond %{DOCUMENT_ROOT}/wp-content/uploads-webpc/$1.jpg.webp -f RewriteRule (.+)\.jpg$ /wp-content/uploads-webpc/$1.jpg.webp [NC,T=image/webp,E=cache-control:no-cache,L] RewriteCond %{HTTP_ACCEPT} image/webp RewriteCond %{DOCUMENT_ROOT}/wp-content/uploads-webpc/$1.jpeg.webp -f RewriteRule (.+)\.jpeg$ /wp-content/uploads-webpc/$1.jpeg.webp [NC,T=image/webp,E=cache-control:no-cache,L] RewriteCond %{HTTP_ACCEPT} image/webp RewriteCond %{DOCUMENT_ROOT}/wp-content/uploads-webpc/$1.png.webp -f RewriteRule (.+)\.png$ /wp-content/uploads-webpc/$1.png.webp [NC,T=image/webp,E=cache-control:no-cache,L] </IfModule> # ! --- DO NOT EDIT NEXT LINE --- ! # END WebP Converter
And the following code at the beginning of .htaccess file in the
/wp-content/uploads-webpc
directory:# BEGIN WebP Converter # ! --- DO NOT EDIT PREVIOUS LINE --- ! <IfModule mod_mime.c> AddType image/webp .webp </IfModule> <IfModule mod_expires.c> ExpiresActive On ExpiresByType image/webp "access plus 1 year" </IfModule> # ! --- DO NOT EDIT NEXT LINE --- ! # END WebP Converter
-
Is the plugin completely free?
-
Yes. The plugin is completely free.
However, working on plugins and technical support requires many hours of work. If you want to appreciate it, you can provide us a coffee. Thanks everyone!
Thank you for all the ratings and reviews.
If you are satisfied with this plugin, please recommend it to your friends. Every new person using our plugin is valuable to us.
This is all very important to us and allows us to do even better things for you!
