What happens when you convert HDR to HEIC?
Transparency
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
Encoding mode
Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained.

Good choice when
- HEIC fits your delivery use: Device photography & image collections.
- You need HDR-capable delivery and can validate its encoding and colour signalling.
- Your receiving application supports the required HEIC variant.
- You can validate the destination’s sample precision and colour interpretation.
- You need a HEIC-compatible workflow that can hold transparency added in a separate edit.
Probably not when
- You require guaranteed scene-linear values or HDR appearance.
- You need a guaranteed output file size or archival pixel equality. Encoder settings do not guarantee either.
- You require identical samples without a defined colour and precision policy.
- You expect automatic background removal or transparency.

- Compression
- HDR: Lossless → HEIC: Lossy & lossless HDR: RLE preserves stored RGBE bytes; RGBE quantization is not exact storage of arbitrary float RGB. The .hdr format is distinct from the general concept of HDR photography. HEIC: HEIC commonly uses lossy HEVC; HEVC also has lossless coding tools. Actual quality, bit depth and chroma depend on the encoded profile and settings, not on the .heic extension.
- Transparency
- Transparency is replaced with white by default. Change the background in Advanced options. Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained.
- Animation
- Still image output. Animated files use only the first frame; animation is not preserved.
- Colour depth
- Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained.
- HDR
- Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained. Availability is checked on this device using native WebCodecs.
- Multiple images
- Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained.
- Dimensions
- Rendered image dimensions are retained within the converter limits; this tool does not offer resizing. Orientation handling depends on the source decoder.
- Metadata
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Common questions
Will HDR automatically survive in HEIC?
Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained. Availability is checked on this device using native WebCodecs.
Will the background become transparent?
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
Which compression mode will HEIC use?
Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained.
Are bit depth and colour values guaranteed to match?
Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained. Availability is checked on this device using native WebCodecs.
Will metadata and colour profiles be retained?
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
