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 HEIC?

HEIC (High Efficiency Image Container) is a modern image format developed by the HEVC industry group. It uses advanced compression to achieve much smaller file sizes than JPEG.

When Should You Use PCX vs HEIC?

Use PCX When...

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

Use HEIC When...

Reach for HEIC when your priority is ios photography, mobile devices — its efficient compression makes sharing fast and storage minimal.

PCX vs HEIC: Key Differences

  • •PCX uses lossless compression while HEIC uses lossy compression — this is the fundamental technical difference between the two formats.
  • •Moving from PCX (lossy) to HEIC (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
  • •How transparency is handled: HEIC does not support alpha channels — transparent areas in the source will become opaque.
  • •Storage footprint: Moderate, similar to uncompressed formats for PCX vs 50% smaller than equivalent JPEG for HEIC.
  • •PCX is optimized for legacy graphics, retro computing while HEIC is designed for ios photography, mobile devices — choose based on your specific workflow needs

Advantages of PCX

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

Advantages of HEIC

  • ✓HEIC applies lossy compression specifically calibrated for iOS photography, mobile devices.
  • ✓HEIC enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓HEIC delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
  • ✓You will find HEIC support built into virtually every tool that handles iOS photography, mobile devices — no plugins or converters needed.

Troubleshooting PCX to HEIC Conversion

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

What is HEIC best used for?

HEIC is ideal for ios photography, mobile devices. HEIF/HEIC - Apple High Efficiency Image Container

Does converting PCX to HEIC lose quality?

Yes, converting PCX to HEIC uses lossy compression, which reduces file size by discarding some visual data. Set quality to 85-95% for a good balance of quality and file size.

What file size should I expect after converting PCX to HEIC?

HEIC files are typically 50-80% smaller than PCX files because HEIC uses efficient lossy compression. The exact reduction depends on quality settings.

Will transparency be preserved when converting PCX to HEIC?

No, HEIC does not support transparency. Any transparent areas in your PCX will be filled with a solid color (usually white) during conversion. Use PNG or WebP if transparency is needed.
