What happens when you convert JPEG XL to PCX?

Animation becomes a still

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

HDR to SDR

HDR is rendered to SDR using exposure and Reinhard tone mapping.

Opaque output

Transparency is replaced with white by default. Change the background in Advanced options.

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.

Is JPEG XL → PCX right for you?

Good choice when

PCX fits your delivery use: Legacy graphics & game assets.
You want a still illustration from an animated source.
You need an SDR delivery copy and can review its tone mapping.
An opaque image is acceptable for your destination.

Probably not when

Motion, frame timing or loop behaviour must survive.
You need the original HDR range for relighting or grading.
You need cutouts or translucent edges for compositing.
You expect lossless encoding to restore lost details or editing structure.

Conversion considerations

An animated JPEG XL has a timed sequence; PCX is a still-image destination in this workflow. A still export loses motion and timing. Frame choice, blending and disposal must be defined by the future engine; a first-frame export is not promised.
If HDR source content is exported through an SDR representation, it needs a display rendering. Values outside the output range require tone mapping, scaling or clipping; brightness relationships can change. Tone mapping, exposure and colour handling depend on the future engine. Renaming or lossless compression cannot preserve out-of-range values.
If JPEG XL contains transparency, PCX cannot retain it as transparent output areas. Those pixels need compositing against an opaque background. Matte colour, alpha interpretation and edge treatment are future engine decisions; no background colour is selected yet.
The reviewed PCX representation uses 8-bit colour samples. If the source contains higher-precision samples, they must be reduced before encoding, even in a lossless output mode. Rounding, dithering and colour conversion are future engine decisions; lost precision cannot be recovered from this output.

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: JPEG XL: Lossy & lossless → PCX: Lossless JPEG XL: Lossless pixels, lossy pixels and reversible recompression of an eligible JPEG bitstream are separate modes. Exact JPEG reconstruction requires its reconstruction data, not just matching rendered pixels. 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.
Animation: Still image output. Animated files use only the first frame; animation is not preserved.
Colour depth: JPEG XL: High-bit-depth samples → PCX: Palette or 24-bit RGB
HDR: JPEG XL: Supported
Layers: JPEG XL: Frame blending; not PSD editing
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.

How will HDR brightness be mapped?

HDR is rendered to SDR using exposure and Reinhard tone mapping.

What happens to transparent areas?

Transparency is replaced with white by default. Change the background in Advanced options.

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.
