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

What happens when you convert PNG to JPEG 2000?
HDR to SDR
HDR is rendered to SDR using exposure and Reinhard tone mapping.
Encoding mode
JPEG 2000 supports reversible lossless and irreversible lossy coding. A JP2 container, an extended JPX/JPF file and a raw J2K codestream are related but not identical file structures. The output uses the implemented still-image encoder; file size depends on the pixels and format.

Compression: LosslessTransparency: YesMetadata: Exif, ICC, Text
Lossless raster images with precise edges and optional transparency. The PNG standard also defines APNG animation.

JPEG 2000
Compression: Lossy & losslessTransparency: YesMetadata: JP2 boxes, ICC, XML (extensions)
Wavelet-based image coding with reversible and irreversible modes. JP2 containers add colour information around the codestream.

Good choice when
- JPEG 2000 fits your delivery use: Specialised scalable imaging.
- 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.
PNG to JPEG 2000 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
- JPEG 2000 supports reversible lossless and irreversible lossy coding. A JP2 container, an extended JPX/JPF file and a raw J2K codestream are related but not identical file structures. 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
- PNG: Lossless → JPEG 2000: Lossy & lossless 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. JPEG 2000: JPEG 2000 supports reversible lossless and irreversible lossy coding. A JP2 container, an extended JPX/JPF file and a raw J2K codestream are related but not identical file structures.
- 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
- PNG: 1–16 bits/sample → JPEG 2000: Component-defined precision
- HDR
- PNG: Third-edition signalling
- 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 JPEG 2000 use?
JPEG 2000 supports reversible lossless and irreversible lossy coding. A JP2 container, an extended JPX/JPF file and a raw J2K codestream are related but not identical file structures. 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.
