What happens when you convert QOI to PCX?
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.

Good choice when
- PCX fits your delivery use: Legacy graphics & game assets.
- An opaque image is acceptable for your destination.
- You need lossless storage of the rendered samples supported by PCX.
- You can validate the destination’s sample precision and colour interpretation.
Probably not when
- You need cutouts or translucent edges for compositing.
- You expect lossless encoding to restore lost details or editing structure.
- You require identical samples without a defined colour and precision policy.

- 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.
- 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
- QOI: Lossless → PCX: Lossless QOI: QOI preserves 8-bit RGB/RGBA samples losslessly. Reducing 16-bit data or discarding profiles and metadata before encoding is outside that guarantee. PCX: PCX RLE is lossless for stored samples. Palette reduction is a separate potentially lossy step; colour planes are channels, not editable composition layers.
- Transparency
- Transparency is replaced with white by default. Change the background in Advanced options.
- Colour depth
- QOI: 8 bits/sample → 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.

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.
