Multiple source images
Only one image is decoded; a concatenated image sequence is not exported as a complete set.

What happens when you convert PGM to PCX?
No new colour information
The source stores grayscale or bitonal values. A colour-capable PCX can represent these tones, but conversion cannot infer original scene colours or recover missing intermediate shades. Colourisation would be a separate image-editing operation.
Lossless sample storage
PCX RLE is lossless for stored samples. Palette reduction is a separate potentially lossy step; colour planes are channels, not editable composition layers. PCX 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.
8-bit destination samples
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.

Good choice when
- PCX fits your delivery use: Legacy graphics & game assets.
- You can choose the source image or part needed for delivery.
- You need the existing gray or binary image in a compatible delivery format.
- You need lossless storage of the rendered samples supported by PCX.
Probably not when
- You require a complete collection, page set or multipart round trip.
- You expect automatic colourisation or reconstruction of absent tones.
- You expect lossless encoding to restore lost details or editing structure.
- You need higher-precision samples for grading or measurement.
PGM to PCX conversion details

- No new colour information

- 8-bit destination samples
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
- 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
- PGM: Uncompressed → PCX: Lossless PGM: Netpbm stores these samples without compression. Reducing colour, thresholding or changing maxval can still lose information before storage; text and binary representations change the layout, not its image meaning. PCX: PCX RLE is lossless for stored samples. Palette reduction is a separate potentially lossy step; colour planes are channels, not editable composition layers.
- Colour depth
- PGM: maxval up to 65535 → PCX: Palette or 24-bit RGB
- 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 every source image be exported?
Only one image is decoded; a concatenated image sequence is not exported as a complete set.
Can conversion restore colour or missing shades?
The source stores grayscale or bitonal values. A colour-capable PCX can represent these tones, but conversion cannot infer original scene colours or recover missing intermediate shades. Colourisation would be a separate image-editing operation.
Does lossless output mean an unchanged source?
PCX RLE is lossless for stored samples. Palette reduction is a separate potentially lossy step; colour planes are channels, not editable composition layers. PCX 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.
