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 PNG?
HDR display encoding
HDR is rendered to SDR using exposure and Reinhard tone mapping.
Lossless sample storage
PNG compression is lossless. Palette conversion, resizing or reducing bit depth before encoding can still discard information. Animation is the APNG extension included in the third edition. PNG 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
- PNG fits your delivery use: Screenshots & transparent graphics.
- 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 expect lossless encoding to restore lost details or editing structure.
JPEG XL to PNG 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.
- Lossless sample storage
- PNG compression is lossless. Palette conversion, resizing or reducing bit depth before encoding can still discard information. Animation is the APNG extension included in the third edition. PNG 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.
- 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 → PNG: 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. PNG: PNG compression is lossless. Palette conversion, resizing or reducing bit depth before encoding can still discard information. Animation is the APNG extension included in the third edition.
- 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 → PNG: 1–16 bits/sample
- HDR
- JPEG XL: Supported → PNG: Third-edition signalling
- 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 PNG?
HDR is rendered to SDR using exposure and Reinhard tone mapping.
Does lossless output mean an unchanged source?
PNG compression is lossless. Palette conversion, resizing or reducing bit depth before encoding can still discard information. Animation is the APNG extension included in the third edition. PNG 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.
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.
