What happens when you convert TIFF to HDR?

Multiple source images

One page is converted (default: page 1). Choose another page in Advanced options.

HDR display encoding

HDR is rendered to SDR using exposure and Reinhard tone mapping.

Opaque output

Transparency is replaced with white by default. Change the background in Advanced options.

Lossless sample storage

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. HDR can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.

Is TIFF → 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 need HDR-capable delivery and can validate its encoding and colour signalling.
An opaque image is acceptable for your destination.

Probably not when

You require a complete collection, page set or multipart round trip.
You require guaranteed scene-linear values or HDR appearance.
You need cutouts or translucent edges for compositing.
You expect lossless encoding to restore lost details or editing structure.

Conversion considerations

TIFF can contain multiple image representations with different roles. These are not automatically a timed animation. Selecting an image, preserving a collection or creating several outputs needs explicit engine support; neither a first-image choice nor an all-images export is implemented.
The source can carry HDR information and HDR has HDR-capable variants. Working radiometric values and display-referred HDR are different representations. Range, primaries, transfer function and signalling must be mapped explicitly; the future engine may instead produce SDR. HDR preservation is not promised by format support.
If TIFF contains transparency, HDR cannot retain it as transparent output areas. Those pixels need compositing against an opaque background. Matte colour, alpha interpretation and edge treatment are future engine decisions; no background colour is selected yet.

Sample precision & colour: Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Metadata & colour: Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Compression: TIFF: Depends on variant → HDR: Lossless TIFF: TIFF is not intrinsically lossless or uncompressed. Read the Compression, BitsPerSample and SampleFormat tags; decoder support varies across schemes. 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: Transparency is replaced with white by default. Change the background in Advanced options.
Colour depth: TIFF: Tagged sample types → HDR: 32-bit RGBE / XYZE pixel
HDR: HDR: Radiometric values
Multiple images: TIFF: Image directories
Dimensions: One page is converted (default: page 1). Choose another page in Advanced options.
Metadata: Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.

Common questions

Will every source image be exported?

One page is converted (default: page 1). Choose another page in Advanced options.

Will HDR automatically survive in HDR?

HDR is rendered to SDR using exposure and Reinhard tone mapping.

What happens to transparent areas?

Transparency is replaced with white by default. Change the background in Advanced options.

Are bit depth and colour values guaranteed to match?

Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.

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.
