What happens when you convert JPEG 2000 to JPEG?
Lossy output
Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG. Quality defaults to 82; adjust it in Advanced options. File size depends on the image and encoder.

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.

A familiar format for photographs. JPEG keeps files compact by trading a little image detail for broad compatibility.

Good choice when
- JPEG fits your delivery use: Photographs & sharing.
- An opaque image is acceptable for your destination.
- You accept lossy encoding for photographic delivery.
- You can validate the destination’s sample precision and colour interpretation.
Probably not when
- You need cutouts or translucent edges for compositing.
- You need an exact pixel reference or repeated lossless editing.
- You require identical samples without a defined colour and precision policy.
JPEG 2000 to JPEG conversion details
- Opaque output
- Transparency is replaced with white by default. Change the background in Advanced options.
- Lossy output
- Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG. Quality defaults to 82; 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 2000: Lossy & lossless → JPEG: Lossy 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. JPEG: Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG.
- Transparency
- Transparency is replaced with white by default. Change the background in Advanced options.
- Colour depth
- 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
What happens to transparent areas?
Transparency is replaced with white by default. Change the background in Advanced options.
Will JPEG preserve every decoded pixel?
Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG. Quality defaults to 82; 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.
