LightPIX is a free online WebP compressor that further reduces WebP file size with no visible quality loss. WebP is a modern image format that already compresses better than PNG or JPEG, which makes it perfect for fast-loading websites — and LightPIX squeezes even more out of it, whether your WebP has transparency or not.
Drop up to 20 WebP files at once (16 MB each), tune the quality, and download them individually or as a single ZIP. Smaller images mean faster pages and better Core Web Vitals. Everything is processed over HTTPS and deleted right after compression — your files are never stored.
For a hands-off setup, the free LightPIX WordPress plugin optimizes WebP images automatically on upload.
Drag & drop, click to browse, or paste a screenshot. PNG, JPEG and WebP are supported — up to 16 MB each and up to 20 at once.
Move the quality slider if you want a smaller file or higher quality. The default already balances size and clarity.
Click Compress all, then download each image or the whole batch as a single ZIP.
A WebP exported by a design tool often still carries wasted data. Re-encoding it with LightPIX at the right quality can shave off a meaningful chunk with no visible difference.
