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 FITS?

Flexible Image Transport System (FITS) is a scientific data format used primarily in astronomy for storing and transmitting images and datasets.

When Should You Use PCX vs FITS?

Use PCX When...

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

Use FITS When...

Reach for FITS when your priority is astronomy, scientific imaging, research — its uncompromising quality ensures every detail is preserved.

PCX vs FITS: Key Differences

  • •PCX and FITS diverge on compression: lossless compression for the source, lossless compression for the target.
  • •Since both PCX and FITS use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
  • •How transparency is handled: FITS supports transparency, so alpha information is preserved during conversion.
  • •Storage footprint: Moderate, similar to uncompressed formats for PCX vs Varies from 1MB to several GB for FITS.
  • •PCX is optimized for legacy graphics, retro computing while FITS is designed for astronomy, scientific imaging, research — choose based on your specific workflow needs

Troubleshooting PCX to FITS Conversion

  • !Converting PCX to FITS gives blurry output → increase the quality setting before conversion
  • !Colors look different in FITS than PCX → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → FITS uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in PCX turned white in FITS → FITS may not support transparency
