About PixSip
PixSip is a free image compressor that runs entirely in your browser. Drop JPG, PNG, WebP, AVIF or HEIC files and get smaller versions back without uploading anything: compression happens locally with WebAssembly builds of the open-source MozJPEG, OxiPNG, libwebp, libavif and libjxl encoders, and the tool keeps working offline once the page has loaded.
There is no quality slider to guess at; PixSip ships one quality setting calibrated against TinyPNG on a 20-image benchmark. Flip one switch to also convert your images to AVIF, JPEG XL, WebP, JPG or PNG, each output shown with its own size and download button.
The free plan handles batches of up to 20 images (10 MB each), strips metadata automatically, offers a before/after Compare view at 1:1, and downloads the whole batch as a ZIP. No signup, no watermark, no ads.
What problem does it solve?
Large JPG/PNG/HEIC images slow down websites and many online compressors require uploading files to a server.
What you can do with it
Compress JPG, PNG, WebP, AVIF and HEIC images and convert them to AVIF, JPEG XL, WebP, JPG or PNG locally in the browser.
