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

What happens when you convert WebP to HDR?
An HDR container adds no captured range
This stores display pixels in RGBE; it does not create new HDR detail.
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.

Good choice when
- HDR fits your delivery use: Lighting environments & radiometry.
- You want a still illustration from an animated source.
- You need an image in an HDR-capable working pipeline.
- An opaque image is acceptable for your destination.
Probably not when
- Motion, frame timing or loop behaviour must survive.
- You expect new highlight or shadow detail from a container change.
- You need cutouts or translucent edges for compositing.
- You expect lossless encoding to restore lost details or editing structure.

- 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
- WebP: Lossy & lossless → HDR: Lossless WebP: Lossy VP8 and lossless VP8L are different coding modes. Lossless WebP preserves supported 8-bit samples, not higher-precision source values. Encoding options can also change RGB values under fully transparent pixels. 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.
- Animation
- Still image output. Animated files use only the first frame; animation is not preserved.
- Colour depth
- WebP: 8 bits/sample → HDR: 32-bit RGBE / XYZE pixel
- HDR
- HDR: Radiometric values
- 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 the output keep animation?
Still image output. Animated files use only the first frame; animation is not preserved.
Can HDR recover clipped highlights?
This stores display pixels in RGBE; it does not create new HDR detail.
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.
