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

What happens when you convert JPEG XL to AVIF?
HDR display encoding
HDR is rendered to SDR using exposure and Reinhard tone mapping.
Encoding mode
AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless. Quality defaults to 55; adjust it in Advanced options. File size depends on the image and encoder.

Good choice when
- AVIF fits your delivery use: Photo delivery & HDR images.
- Your destination supports the required animation variant.
- You need HDR-capable delivery and can validate its encoding and colour signalling.
- You need a transparency-capable destination and will check its supported variant.
Probably not when
- You require guaranteed animation transfer from the unavailable converter.
- You require guaranteed scene-linear values or HDR appearance.
- 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 AVIF conversion details
- Animation-capable destination
- Still image output. Animated files use only the first frame; animation is not preserved.
- HDR display encoding
- 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
- AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless. Quality defaults to 55; adjust it in Advanced options. File size depends on the image and encoder.
- 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 → AVIF: Lossy & lossless 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. AVIF: AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless.
- 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 → AVIF: 8 / 10 / 12 bits
- HDR
- JPEG XL: Supported → AVIF: Optional; colour properties
- 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
Can the animation be transferred between formats?
Still image output. Animated files use only the first frame; animation is not preserved.
Will HDR automatically survive in AVIF?
HDR is rendered to SDR using exposure and Reinhard tone mapping.
Which compression mode will AVIF use?
AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless. Quality defaults to 55; adjust it in Advanced options. File size depends on the image and encoder.
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.
