HEIC from an iPhone into JPG, JPG into WebP, a 6 MB photo into a 400 KB one. The pictures never leave your computer: the page decodes and re-encodes them itself.
Drop pictures hereor tap to choose. HEIC, JPG, PNG, WebP, GIF, BMP — as many as you like.
Empty keeps the original size. 2000 is plenty for a screen; 1200 for a chat.
Nothing here yet — add a picture above.
HEIC is decoded here, on the page, by libheif compiled to WebAssembly — the same library Linux uses. It is the only way to open an iPhone photo in a browser without sending it anywhere.
Re-encoding drops the metadata a camera writes into a file — location, time, serial number. That is what you want before posting; if you need it kept, keep the original.
Everything happens on this page: decoding, resizing and saving are done by your browser. No request carries your picture anywhere, nothing is stored, and there is no account. Once the page is open it works without a network.
