Advanced options
  • Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
  • Transparency is replaced with white by default. Change the background in Advanced options.
  • This stores display pixels in RGBE; it does not create new HDR detail.
  • Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported.
  • HEIF container: libheif (LGPL); licences, source and relink files

What happens when you convert HEIF to HDR?

Multiple source images

Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported. Availability is checked on this device using native WebCodecs.

Animation becomes a still

Still image output. Animated files use only the first frame; animation is not preserved.

HDR display encoding

Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported. Availability is checked on this device using native WebCodecs.

Lossless sample storage

Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported. Availability is checked on this device using native WebCodecs.

Is HEIF → HDR right for you?

Good choice when

  • HDR fits your delivery use: Lighting environments & radiometry.
  • You can choose the source image or part needed for delivery.
  • You want a still illustration from an animated source.
  • You need HDR-capable delivery and can validate its encoding and colour signalling.

Probably not when

  • You require a complete collection, page set or multipart round trip.
  • Motion, frame timing or loop behaviour must survive.
  • You require guaranteed scene-linear values or HDR appearance.
  • You need cutouts or translucent edges for compositing.

Sample precision & colour
Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported. Availability is checked on this device using native WebCodecs.
Metadata & colour
Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported. Availability is checked on this device using native WebCodecs.
Compression
HEIF: Depends on variant → HDR: Lossless HEIF: HEIF defines the container. Compression may be lossy, lossless or uncompressed depending on its codec binding; one global quality or bit-depth value would be misleading. 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.
Transparency
Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported.
Animation
Still image output. Animated files use only the first frame; animation is not preserved.
Colour depth
Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported.
HDR
Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported. Availability is checked on this device using native WebCodecs.
Multiple images
Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported.
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
