Visually identical to the original
SSIM‑targeted means we only spend “lossy” budget where the human eye can’t see it. No banding in skies, no chunky skin tones, no smeared text edges.
SSIM-TARGETED COMPRESSION · LIVE
Shrink images by 60%+.
Keep them looking identical.
The same structural‑similarity algorithm professional studios use to optimise photos — free in your browser, in code via a single REST endpoint, or as a drop‑in WordPress plugin.

Why image weight matters
Heavy images are the #1 reason Lighthouse marks a page as slow. Slow pages bleed traffic to faster competitors, hurt SEO via Core Web Vitals, and cost real money in bandwidth at scale. But the usual “fix” — cranking JPEG quality down — introduces visible banding in skies, blotches in skin tones, and blocky artefacts in fine textures. SSIM compression is the fix to the fix.
3 things every team gets
Real savings, real speed
Typical photos shrink 60–90%. Lighter pages mean better Largest Contentful Paint scores, healthier Core Web Vitals, and meaningfully lower CDN bills at scale.
Built into your stack
One REST endpoint for code. A WordPress plugin for sites — single‑site or multisite, WooCommerce stores, NextGEN galleries. The browser tool here if you only need to do a handful.
See what “lossless‑looking” means
Both images below were compressed to roughly the same file size. Drag the divider to compare a naive low‑quality JPEG with SSIM Compress’ output. Keyboard: focus the handle, then press ← / →.
Standard JPEG · q=18 · 7 KB
SSIM Compress · q=70 · 9 KB
Built for WordPress sites
Drop the plugin into any WordPress install — per‑site or network‑activated for multisite. It runs entirely in the background, never blocks the editor, and processes every JPG and PNG in the media library. WooCommerce product photos and NextGEN galleries included.
