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. ## Screenshots * [[ * Dashboard overview with plan, quota, and quick actions * [[ * Exclusions browser with search, filters, and select-all * [[ * Backup & Restore tools including export/import and restore selected * [[ * Activity log and live progress indicators ## Installation 1.

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. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “ImgSmaller – Optimize Images | Compress Images | Convert WebP & AVIF” is open source software.
