Convert iPhone HEIC photos without uploading them
iPhones save photos as HEIC, which many apps and websites still reject. Most "free HEIC converters" make you upload your personal photos to their servers. This one decodes HEIC directly in your browser - your photos never leave your device, and there's no file limit.
How to convert an image
- Drop your images above - HEIC, AVIF, WebP, PNG, JPG, GIF and BMP all work.
- Pick the output format. JPG opens everywhere; WebP and AVIF are far smaller at the same quality; PNG keeps transparency.
- Click Convert images and download the results.
What about AVIF?
AVIF is the newest mainstream image format, typically 20-30% smaller than WebP. Every modern browser can read AVIF, so converting AVIF → JPG/PNG/WebP always works here. Creating AVIF files is newer browser territory - if your browser can't encode AVIF, the option above is disabled automatically.
FAQ
Does this Image Converter upload files to a server?
- No. Decoding and conversion happen locally in your browser. Nothing is transmitted or stored.
Why is HEIC conversion slower than the others?
- HEIC isn't natively supported by browsers, so we load a small decoder (WebAssembly) the first time you add a HEIC file. It runs on your device like everything else.
Does converting lose quality?
- To JPG/WebP/AVIF: a controlled, usually invisible amount at 85%. To PNG: lossless, but larger files.
Is there a limit on the number of files?
- No artificial limit - batch as many as your device's memory allows.
