Unlimited image compression. No API keys. No quotas. Squeeze compresses images and converts them to WebP locally in your browser—no monthly caps, no third-party uploads.
Unlike cloud-based plugins, Squeeze:
♾️ No compression limits — squeeze your entire Media Library, not just the first 100–500 images per month.
☁️ No third-party servers — images never leave your site; processing happens locally in the browser (ideal for GDPR-sensitive and membership sites).
⚡ Direct WebP conversion — convert JPG/PNG to WebP and replace the original file on disk (no duplicate copies cluttering storage).
🖼️ Optimize on upload — compress in Gutenberg, GenerateBlocks, and the Voxel theme before files hit the server (Elementor on-upload squeeze is available in Premium).
The result: smaller files, faster page loads, and lower hosting storage—without SaaS fees or API keys.

🌟 New in 1.7.x
- Direct WebP conversion: Convert JPG/PNG to WebP and replace originals—save storage without duplicate files.
- Pre-upload compression: Shrink images in the browser before upload (Gutenberg, GenerateBlocks, Voxel create-post and gallery fields).
- Three WebP delivery modes: Direct WebP, separate squeeze-webp folder with URL rewrite, or server-side delivery via .htaccess.
- Voxel theme support: Pre-upload squeeze on multipart AJAX uploads in create-post and file/gallery fields.
- WP Offload Media support: Compress CDN-hosted images (including when local files are removed), auto-detect provider/CDN URLs, and sync compressed/Direct WebP files to S3, GCS, DigitalOcean Spaces, and similar—Direct WebP recommended (sidecar WebP modes are not compatible with Offload).
- WordPress 7.1: While Squeeze on upload is on, core’s built-in browser image processing is turned off so Gutenberg uploads keep Squeeze quality, Direct WebP, and backups. Turn on-upload off to use WordPress HEIC conversion and HDR thumbnails.
✨ Key Features
- Faster pages: Smaller images improve load time, Core Web Vitals, and mobile bandwidth use.
- WebP conversion & serving: Convert to WebP and serve efficiently—choose Direct WebP, HTML URL rewrite, or .htaccess delivery for supported browsers.

.bakcopy to restore the original after squeezing. - Formats: JPEG, PNG, WebP, and AVIF.

How does Squeeze work?
Open the Media Library, run Bulk Squeeze, or upload a new image — Squeeze runs Google Chrome team–backed codecs (the same family as Squoosh.app) inside your browser via Web Workers. No account, no API key, no off-site upload queue.
