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 WebP?
HDR to SDR
HDR is rendered to SDR using exposure and Reinhard tone mapping.
Encoding mode
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. Quality defaults to 80; adjust it in Advanced options. File size depends on the image and encoder.
8-bit destination samples
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.

Good choice when
- WebP fits your delivery use: Web images & short animations.
- Your destination supports the required animation variant.
- 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
- You require guaranteed animation transfer from the unavailable converter.
- 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 WebP conversion details
- Animation-capable destination
- 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
- 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. Quality defaults to 80; adjust it in Advanced options. File size depends on the image and encoder.
- 8-bit destination samples
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
- 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 → WebP: 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. 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.
- 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 → WebP: 8 bits/sample
- 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
Can the animation be transferred between formats?
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 WebP use?
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. Quality defaults to 80; 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.
