Drop a photo, get a copy guaranteed under 50 KB at the best quality that fits. Nothing is uploaded — it all happens in your browser.
50 KB is the classic application-form limit — ID photos, admit cards, registration portals and older job sites cap uploads around here. It's small by modern standards (a phone photo is typically 2–5 MB), but it's a comfortable budget for what those forms actually display: a photo a few hundred pixels wide.
50 KB comfortably holds a sharp image around 800–1000 px on the long edge at reasonable JPEG quality. Faces, documents and screenshots survive well. If your source is a full-resolution camera photo, PixFit will scale it down as part of hitting the budget — that's the right trade: fewer, cleaner pixels beat many blocky ones. If the form specifies exact dimensions, put them in the "Exact size" field (e.g. 200x230) — you get precisely those pixels, still under 50 KB, at noticeably better quality than compressing the full-size photo.
The typical "compress to 50kb" site uploads your ID photo to their server, compresses it there, and serves it back. There is no reason a form photo — often literally your face next to your name — needs to make that trip. PixFit does the identical job locally: the file never leaves your device, and you can verify that by loading this page and then switching off your connection before dropping the photo.
