Final Size

Read full description

Set the quality for each format. Watch the new file size update before you save. Then send it wherever it needs to go. That is the whole app. There is no step four. EVERY FORMAT WORTH SHRINKING AVIF, HEIC, JPEG, JPG, PNG, and WebP. Compress in place, or convert between them — turn the HEIC your iPhone shot into a JPEG anyone can open, or a PNG into WebP for the web. WHAT YOU GET - Real-time preview, so you never guess how a setting will look - Quality settings per format, not one blunt slider for everything - AVIF and WebP support, which most compressors still leave out - Share to AirDrop or Messages, or save straight back to your library WORKS OFFLINE, ALWAYS Most compressors send your photos to a server and send them back smaller. Final Size does the work on your phone. It runs on a plane, in a basement, or on airplane mode — and your photos never sit on someone else's machine, metadata and all. No accounts, no tracking. PERFECT FOR - Photographers clearing space on a full phone - Developers optimizing assets for the web - Anyone emailing a photo that came back "file too large" Download Final Size and try it on the biggest photo in your library.
