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

What happens when you convert JPEG XL to BMP?
HDR to SDR
HDR is rendered to SDR using exposure and Reinhard tone mapping.
Encoding mode
BMP may be uncompressed or use a header-selected encoding. Alpha is header-dependent; 32 bits alone do not establish transparency support in the receiving application. The output uses the implemented still-image encoder; file size depends on the pixels and format.

JPEG XL
JPEG XL Image Coding System
Compression: Lossy & losslessTransparency: YesMetadata: Exif, XMP, ICC, JUMBF
A JPEG-family image system for lossy and lossless pictures, high precision, alpha and animation.

Target
BMP
Windows Bitmap
Compression: Depends on variantTransparency: YesMetadata: DIB header, ICC (V5)
Windows raster storage with several DIB header versions. Simple uncompressed pixels are common, but alpha and compression vary.

Good choice when
- BMP fits your delivery use: Windows bitmap interchange.
- You want a still illustration from an animated source.
- You need an SDR delivery copy and can review its tone mapping.
- You need a transparency-capable destination and will check its supported variant.
Probably not when
- Motion, frame timing or loop behaviour must survive.
- You need the original HDR range for relighting or grading.
- You assume format-level alpha support guarantees matching transparent edges.
- You need a guaranteed output file size or archival pixel equality. Encoder settings do not guarantee either.
JPEG XL to BMP conversion details
- Animation becomes a still
- Still image output. Animated files use only the first frame; animation is not preserved.
- HDR to SDR
- HDR is rendered to SDR using exposure and Reinhard tone mapping.
- Transparency representation
- The implemented target supports alpha. Display-pixel processing can round translucent samples; archival sample equality is not promised.
- Encoding mode
- BMP may be uncompressed or use a header-selected encoding. Alpha is header-dependent; 32 bits alone do not establish transparency support in the receiving application. The output uses the implemented still-image encoder; file size depends on the pixels and format.
- 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
- JPEG XL: Lossy & lossless → BMP: Depends on variant JPEG XL: Lossless pixels, lossy pixels and reversible recompression of an eligible JPEG bitstream are separate modes. Exact JPEG reconstruction requires its reconstruction data, not just matching rendered pixels. BMP: BMP may be uncompressed or use a header-selected encoding. Alpha is header-dependent; 32 bits alone do not establish transparency support in the receiving application.
- 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
- JPEG XL: High-bit-depth samples → BMP: 1 / 4 / 8 / 16 / 24 / 32 bpp
- HDR
- JPEG XL: Supported
- Layers
- JPEG XL: Frame blending; not PSD editing
- 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.
How will HDR brightness be mapped?
HDR is rendered to SDR using exposure and Reinhard tone mapping.
Which compression mode will BMP use?
BMP may be uncompressed or use a header-selected encoding. Alpha is header-dependent; 32 bits alone do not establish transparency support in the receiving application. The output uses the implemented still-image encoder; file size depends on the pixels and format.
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.
