iPhones save photos as HEIC by default — a format that saves space but doesn’t open everywhere, especially on Windows, older apps, or when you’re uploading to a site that expects a JPG. This tool converts your HEIC and HEIF photos to JPG instantly, without uploading a single file anywhere. Everything happens locally in your browser: drop in one photo or a whole batch, and download standard JPGs you can use anywhere — fast, free, and completely private.
