About PhotoReducer

PhotoReducer is a free suite of image tools — compress, resize, convert, crop to exact sizes — built on one principle: your photos are yours. Every tool runs entirely in your browser using WebAssembly, so your images are never uploaded to a server. Not ours, not anyone's.

How it works

We compile the same battle-tested engines used by professional software — MozJPEG, libwebp, libavif, Oxipng — to WebAssembly, so they run at native speed on your device. When you drop a photo, your own computer does the work. That is why PhotoReducer is fast, free without limits, and safe for sensitive documents like ID and visa photos.

Free, supported by ads

The site may show advertising to cover its costs. Ads never affect your images — which, again, never leave your device. See our privacy policy for details.
