Reasons to switch from HEIF to EXR
- Huge dynamic range
- Lossless floating-point colour
- Standard in film pipelines
- Works with: Blender, Nuke, After Effects, Photoshop and Houdini
What to expect from this conversion
- EXR can be saved lossy or lossless. Quality 100 gives a lossless result where the format supports it, and lower values give smaller files.
- Transparency is kept in the EXR file.
- EXR cannot store animation here, so only the first frame of an animated HEIF is saved.
- EXR stores light in linear floating-point values, so your pixels are converted from sRGB to linear. The result looks the same in an HDR-aware viewer but does not gain real dynamic range.
- Browsers do not display EXR 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.
