What is PCX?

PCX (PC Paintbrush) is a legacy raster image format from the early days of DOS, originally created for ZSoft's PC Paintbrush.

What is PBM?

Portable BitMap (PBM) is a simple monochrome image format that stores each pixel as either black or white in an ASCII text representation.

When Should You Use PCX vs PBM?

Use PCX When...

Reach for PCX when your priority is legacy graphics, retro computing — its uncompromising quality ensures every detail is preserved.

Use PBM When...

Reach for PBM when your priority is simple image processing, scientific visualization — its uncompromising quality ensures every detail is preserved.

PCX vs PBM: Key Differences

  • •PCX uses lossless compression while PBM uses lossless compression — both take the same approach to file size management.
  • •Since both PCX and PBM use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
  • •Alpha channel support: PBM lacks transparency support.
  • •File sizes: PCX files typically range Moderate, similar to uncompressed formats and PBM files Very compact for monochrome images.
  • •Primary audience: PCX is built for legacy graphics, retro computing scenarios, while PBM focuses on simple image processing, scientific visualization — pick the format that matches your output requirement.

Advantages of PCX

  • ✓PCX uses lossless compression tailored for Legacy graphics, retro computing.
  • ✓PCX is supported natively on virtually every device, browser, and operating system.
  • ✓PCX files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓PCX integrates seamlessly with all major creative tools and workflows.

Advantages of PBM

  • ✓At its core, PBM relies on lossless encoding — a design choice that makes it perfect for Simple image processing, scientific visualization.
  • ✓You won't run into compatibility issues with PBM — it's a universal standard across platforms.
  • ✓File size management with PBM: larger files guaranteed to match the original exactly.
  • ✓Every major application in the Simple image processing, scientific visualization space supports PBM natively.

Troubleshooting PCX to PBM Conversion

  • !PBM shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted PBM image looks washed out → the source PCX likely uses a wider color space than PBM supports
  • !PBM file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted PBM looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
