Pixel decoding and image re-encoding: how PCX becomes JPG

Zsoft paintbrush-era raster data using palette or run-length encoded pixels is decoded into a working pixel canvas first, then written back out under JPG's own color and compression model. Dimensions can stay exactly the same even as encoding, metadata, and fine detail change underneath. PCX decoding follows version, plane count, bytes-per-line padding, palette placement, run-length encoding, dimensions, and scanline order from its header. JPG delivery writes opaque, lossy photographic pixels; quality must be judged around high-contrast edges, gradients, fine texture, orientation, and repeated-encode damage.

When to actually choose PCX to JPG

JPG wins this route whenever its specific mix of compatibility, alpha, animation, and file size fits the destination better than PCX does.

What changes between the PCX model and the JPG deliverable

Because JPG compresses lossily, verify the actual playback or viewing quality rather than assuming an unchanged size means an unchanged result.
Metadata handling differs between PCX and JPG; do not assume every application-specific field carries across untouched.

What the PCX source carries and the JPG output demands

PCX

What can fail when PCX raster image is interpreted

Modern software may mishandle old palettes, planar channels, or uncommon bit-depth variants.

JPG

What JPEG image cannot safely promise

Repeated encoding introduces ringing or blocks, and transparent areas must become opaque.

How the JPG writer handles this route

lossy JPEG-compressed pixels optimized for photographs and broad compatibility is what gets written, labeled as image/jpeg. Whether that actually opens depends on the receiving application, not on the file extension.

How to confirm the converted JPG actually works

BEFORE

Record the PCX evidence before conversion

Check palette colors, dimensions, orientation, bit depth, and whether indexed transparency was expected.

AFTER

Test the JPG file in its receiving workflow

View text edges, faces, gradients, and high-contrast detail at the intended display size.
