About CompressPix

CompressPix is a free, browser-based image compressor for JPG, PNG, and WebP files. Everything happens locally on your device — your images never leave your browser.

How it works

We use a high-performance JavaScript compression engine that runs inside a Web Worker, so your browser stays responsive while it shrinks photos. You control the quality with a slider, see the result instantly, and download — alone or as a ZIP.

Why we built it

Most online compressors upload your photos to a server you don't control. We wanted a tool that's faster, safer, and free of accounts and limits. CompressPix is the simplest way to send smaller images by email, post to the web, or save space.
