Reasons to switch from HDR to HEIC
- About half the size of JPG at the same quality
- Stores depth maps and Live Photos
- Default for iPhone photos
- Works with: iOS, macOS, recent Windows (with extension) and Android 10+
What to expect from this conversion
- HDR is lossless and HEIC is lossy, so the file will usually get much smaller. Use the quality slider to balance size and detail.
- HDR holds values brighter than a normal screen can show, so the image is clipped to the displayable range and converted to sRGB. Very bright highlights lose their extra range.
- Output is HEVC-based, so check that the devices you share with can open it. If not, JPG is the safer choice.
- Browsers do not display HEIC files, so use it in editors, print workflows or development tools rather than on a web page.

Tips for the best result
- Use quality 80 to 90 for photos: it is visually close to the original at a much smaller size.
- Set a width if the image will be shown on a small screen, which also reduces the file size.
- Choose a background colour before converting transparent images to a format without transparency.
