How does it work?

After you upload an image to your WordPress site, each resized image is uploaded to the TinyJPG or TinyPNG service. Your image is analyzed to apply the best possible optimization. Based on the content of your image an optimal strategy is chosen. The result is sent back to your WordPress site and will replace the original image with one smaller in size. On average JPEG images are compressed by 40-60% and PNG images by 50-80% without visible loss in quality. Your website will load faster for your visitors, and you’ll save storage space and bandwidth!

Getting started

Install this plugin and obtain your free API key from https://tinypng.com/developers. With a free account you can optimize roughly 100 images each month (based on a regular WordPress installation). The exact total depends on the number of thumbnail sizes that are in use in your WordPress installation. You can change which of the generated thumbnail sizes should be optimized in the Settings > Media page. If you’re a heavy user you can optimize more images for a small additional fee.

Optimizing all your images

You can optimize all your JPEG and PNG images at once by going to Media > Bulk Optimization. Clicking on the big button will start optimizing all unoptimized images in your media library.

Multisite support

The API key can optionally be configured in wp-config.php. This removes the need to set a key on each site individually in your multisite network.

FAQ

Q: How many images can I optimize for free?

A: In a default WordPress installation you can optimize around 100 images for free each month. WordPress creates different thumbnails of your images which all have to be compressed. Some plugins even add more sizes, so take a look at the Settings > Media page before you start optimization.

Q: What happens to the optimized images when I uninstall the plugin?

A: When you remove the plugin all your optimized images will remain optimized.

Q: I don’t recall uploading 500 photos this month but my limit is already reached. How is this number calculated?

A: When you upload an image to your website, WordPress will create different sized versions of it (see Settings > Media). The plugin will compress each of these sizes, so when you have 100 images and 5 different sizes you will do 500 compressions.

Q: Is there a file size limit?

A: No. There are no limitations on the size of the images you want to compress.

Q: What happens when I reach my monthly limit?

A: Everything will keep on working, but newly uploaded images will not be optimized. Of course we encourage everyone to sign up for a paid account to cover the hosting and development costs of the service.

Q: Can I optimize all existing images in my media library?

A: Yes! After installing the plugin, go to Media > Bulk Optimization, and click on the start button to optimize all unoptimized images in your media library.

評価

On my must-have plugin list!

I have been using the TinyPNG website to optimize image for all my online needs. Its awesome to have the nifty capability embedded right into a cool wordpress plugin where once activated you don’t have to perform any additional steps to optimize the images that are uploaded.

No issues so far. Thanks to the developers for making this available and keeping it up to date!

Excellent

Easy to install and to use. Excellent compression without undue loss of image quality.

Was great, now more trouble than it’s worth.

This was a great service and one I would have gladly paid more for than I ever actually did. Sadly, an over generous free-tier now means that you are often sat waiting for minutes while a single image is processed (if at all).

If you don’t ever intend to pay for use than you’ll probably be happy with the service but if you are a professional developer, who doesn’t mind paying, it’s just not worth the hassle.

Great Plugin but missing options

It’s great that Tiny PNG offer this Plugin for free with a reasonable amount of images per month.

I’d just like to be able to use the plugin for PNG only. Turn off JPEG compression. Maybe I’ve just missed this option? but it would, for me anyway, be 5 stars with this functionality.

PS. I’ve been using your web PNG compressor for years and I’m a big fan! : )

Excellent plugin with excellent support.

This plugin is fantastic. I’ve found that it optimizes files more than other services out there. It is great that it automatically optimizes the images on upload.

Also, their support is fantastic. A recent update caused the plugin to stop working on my sites, and after commenting in the support thread, they reached out to me the next day. Within another day, they had a temporary fix to me and said they would be implementing it in the next update. Awesome!!!
