Why iPhone photos are saved as HEIC
Since iOS 11, iPhones save photos in HEIC (High Efficiency Image Container) by default. It stores images with HEVC compression, which produces files roughly half the size of a comparable JPG. That is great for phone storage, but support outside the Apple world is patchy. Windows often asks for an extra codec, many websites reject .heic uploads, and plenty of photo editors and printing kiosks simply won’t open them.
This converter decodes HEIC and HEIF files directly in your browser and saves them as standard JPG or PNG. The decoder (libheif compiled to WebAssembly) downloads once on first use, about 1–2 MB, and is cached so later visits start immediately, even offline.
JPG or PNG: which output to choose
| JPG | PNG | |
|---|---|---|
| Typical file size | Small | Several times larger |
| Compression | Lossy, adjustable quality | Lossless |
| Best for | Sharing, email, web forms, prints | Editing, archiving a working copy |
| Opens everywhere | Yes | Yes |
For most people JPG is the right answer. A quality of 85–92 is a good range for photos: below 80 you may notice blockiness in skies and smooth gradients, and above 95 the file grows quickly for little visible gain.
Choose PNG when you plan to retouch the photo in an editor and save it several times. Each JPG save recompresses the image, while PNG keeps every pixel exactly as decoded.
What happens to photo metadata
iPhone photos carry EXIF data: capture date, camera and lens model, exposure settings and, if Location Services was on, the exact GPS coordinates where the photo was taken.
- Location is always stripped. You can share converted photos without revealing where they were taken.
- Keep metadata on: the date, camera model and other EXIF fields are kept in JPG output, so photo libraries still sort the pictures correctly.
- Keep metadata off: all EXIF is removed for the cleanest, most private file.
Common problems and fixes
Live Photos and bursts. A Live Photo is a HEIC still plus a short video file. This tool converts the still image; the motion part is a separate .mov file and is not included.
Photo looks rotated. iPhones often store orientation as a flag rather than rotating the pixels, and some older apps ignore that flag. Try an up-to-date viewer first; if the photo is still sideways, a rotate tool fixes it in seconds.
Colors look slightly different. Newer iPhones capture in a wide color space (Display P3). Most screens and browsers show the converted file correctly, but some older software assumes sRGB and may display colors a little duller.
A file won’t convert. Make sure it really is HEIC or HEIF and not a renamed file or a video. Very large files near the 100 MB limit may also hit your device’s memory limits; try converting them one at a time.
Avoid HEIC in the future
If you regularly need JPGs, you can change the setting on your iPhone: Settings > Camera > Formats > Most Compatible. New photos will be saved as JPG, at the cost of using more storage. Alternatively, iOS converts photos to JPG automatically when you transfer them with Settings > Photos > Transfer to Mac or PC > Automatic.
