Looking for a WordPress image optimizer without an API key? Squeeze is a local WebP converter that lets you compress images in WordPress, convert uploads to WebP, and bulk compress your media library without ShortPixel-, Imagify-, or Smush-style monthly caps. Processing runs in your admin browser—unlimited squeezes, full privacy, and no uploads to third-party compression servers.
If you need a webp converter wordpress plugin, a shortpixel alternative without recurring API fees, or an image optimizer without api keys, Squeeze keeps optimization on your server and in your browser instead of a SaaS queue.
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 <a href="https://pluginarium.com/squeeze/#premium" rel="nofollow ugc">Premium</a>).
The result: smaller files, faster page loads, and lower hosting storage—without SaaS fees or API keys.

<h3>How does Squeeze work?</h3>
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.
