Prep images before they touch your WordPress site
Every other image plugin optimizes after upload — the heavy originals still travel to your server and still fill your disk. Squishify flips the order: compress, convert, and resize in your browser, then upload only the finished files to your Media Library.
Free · WordPress 6.5+ · Now on the WordPress.org plugin directory · See what’s in Pro
Optimize first. Upload second.
Squishify runs the same encoders behind squoosh.app — libavif, libwebp, MozJPEG, and Oxipng — as WebAssembly, right in your browser, inside wp-admin.
True privacy
Processing happens on your machine. Images never touch a third-party service — the only transfer is the final upload to your own site.
Save server space
Full-size originals never reach your server, and uploads stay under WordPress’s own 2560px limit — so WP never stores a “-scaled” duplicate either.
Faster page loads
Ship modern AVIF and WebP at exactly the size your pages need — dramatically smaller files, dramatically better Core Web Vitals.
Batch workflow
Queue up to 50 images, tune one, then apply the format and quality to the whole batch in a click.
Before / after preview
A live comparison loupe on every image — drag the divider and see exactly what a quality setting costs before you commit.
No API keys, no quotas
No usage costs, no monthly credit meter — your browser does the work, so optimizing 5 images costs the same as 5,000.
Three steps, right inside wp-admin
Click the Squishify button in your Media Library and a full-screen editor opens over WordPress.
