Transparency
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.

What happens when you convert PCX 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.

Good choice when
- JPEG 2000 fits your delivery use: Specialised scalable imaging.
- Your receiving application supports the required JPEG 2000 variant.
- You can validate the destination’s sample precision and colour interpretation.
- You need a JPEG 2000-compatible workflow that can hold transparency added in a separate edit.
Probably not when
- 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.
- You expect automatic background removal or transparency.
PCX to JPEG 2000 conversion details
- Transparency
- The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
- 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
- PCX: Lossless → JPEG 2000: Lossy & lossless PCX: PCX RLE is lossless for stored samples. Palette reduction is a separate potentially lossy step; colour planes are channels, not editable composition layers. 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.
- Colour depth
- PCX: Palette or 24-bit RGB → 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 background become transparent?
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
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.
