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

What happens when you convert GIF to JPEG 2000?
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.

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 a transparency-capable destination and will check its supported variant.
- Your receiving application supports the required JPEG 2000 variant.
Probably not when
- Motion, frame timing or loop behaviour must survive.
- 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.
- You require identical samples without a defined colour and precision policy.
GIF to JPEG 2000 conversion details
- Animation becomes a still
- Still image output. Animated files use only the first frame; animation is not preserved.
- 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
- GIF: Lossless → JPEG 2000: Lossy & lossless GIF: LZW compression is lossless for the stored palette indices. Colour reduction before encoding is not lossless for an arbitrary RGB source. 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
- GIF: Up to 256 colours/table → JPEG 2000: Component-defined precision
- 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.
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.
