About this tool
HEIC (High Efficiency Image Container) is the format the iPhone uses to save photos — it stores great quality in a small file, but many websites, Windows apps and older programs can't open it. Converting to JPG gives you a universally-supported image you can upload, email or edit anywhere.
This converter decodes HEIC entirely in your browser and re-encodes it as JPG, so the photo is never uploaded to a server — important for personal pictures. Drop one file or a whole batch; each converts in turn with a progress indicator, and you can grab them individually or as a single ZIP.
Everything runs locally in your browser — your photos are never uploaded.
Frequently asked questions
Why can’t I open HEIC files on Windows or the web?
HEIC is an Apple-favoured format; Windows and many web apps need an extra codec to read it. Converting to JPG produces a file that opens everywhere without any plugin.
Are my photos uploaded anywhere?
No. Decoding and conversion happen in your browser using WebAssembly; the image data never leaves your device, which is what makes this safe for personal photos.
Does converting to JPG lose quality?
JPG is lossy, so there is a small quality trade-off, but the converter uses a high quality setting (about 92%) so the difference is hard to see. For a smaller file, run the result through the image compressor.
