## 説明

ImgSmaller integrates with the ImgSmaller API to compress images in your Media Library.
It supports WEBP and AVIF output, runs in the background via WP-Cron or external
cron, and includes robust backups and one-click restore. It also provides an exclusions
browser, export/import of backups and replacements, and plan/quota awareness.

Key features:

 * Background image optimization with batching
 * WEBP and AVIF output formats
 * Automated backup of originals and one-click restore (all or selected)
 * Export/import backups ZIP; import optimized replacements ZIP
 * Exclusions browser with search, filters, and infinite scroll
 * Quota-aware processing with countdown and auto-resume
 * Secure tokenized public endpoints and file proxy for private media
 * Dashboard metrics, logs, and plan/allowed domains management
 * External cron support with copyable URL and token regeneration

### External services

This plugin connects to the ImgSmaller API to compress images and retrieve plan/
quota information.

What is the service and what is it used for?
 – The ImgSmaller API (https://imgsmaller.
com) provides image compression and account information used by this plugin to optimize
your Media Library and display plan/quota details.

What data is sent and when?
 – When you start compression, the plugin sends the 
public URL of each selected attachment (or a secure, tokenized proxy URL if the 
file is not publicly accessible) along with your API key to request compression.
After polling completes, the plugin downloads the optimized image bytes. – When 
viewing plan info, the plugin requests your current plan usage and limits using 
your API key.

Where can I find the service policies?
 – Terms of Service: https://imgsmaller.com/
terms – Privacy Policy: https://imgsmaller.com/privacy

Notes:
 – You can disable background processing at any time from the dashboard. 
If you prefer not to send any files or metadata, do not start compression and do
not enter an API key.

## インストール

    ImgSmaller` in `wp-content/plugins/`.
 2. Activate the plugin through the Plugins menu in WordPress.
 3. Go to ImgSmaller in the admin menu.
 4. Enter your ImgSmaller API key and click Connect.

    dashboard.

## FAQ

### Do I need backups enabled?

Backups are recommended to restore originals and to export backups. You can disable
them if you have another backup strategy.

### Will this work with private or protected content?

Yes. If ImgSmaller cannot access a file directly, the plugin retries via a secure
file proxy route.

### How does quota blocking work?

When the daily limit is reached, the plugin pauses enqueueing new jobs and shows
a countdown. It auto-resumes after reset.

### Can I restore only specific images?

Yes. Use the Restore browser to search and select images to restore.

### Does it support AVIF?

Yes. Choose AVIF in settings.
