What is HEIF?

HEIF (High Efficiency Image File Format) is a modern container format that stores images encoded with the HEVC (H.265) codec. It delivers significantly smaller file sizes than JPEG while maintaining superior image quality.

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.

When Should You Use HEIF vs PCX?

Use HEIF When...

Reach for HEIF when your priority is modern photography, ios/macos workflows, efficient storage and sharing — its efficient compression makes sharing fast and storage minimal.

Use PCX When...

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

HEIF vs PCX: Key Differences

  • •HEIF and PCX diverge on compression: lossy compression for the source, lossless compression for the target.
  • •The switch from lossy compression to lossless compression means you preserve full quality at the expense of larger file sizes.
  • •Transparency: N/A - PCX does not support transparency
  • •File sizes: HEIF files typically range 40-50% smaller than equivalent JPEG and PCX files Moderate, similar to uncompressed formats.
  • •Primary audience: HEIF is built for modern photography, ios/macos workflows, efficient storage and sharing scenarios, while PCX focuses on legacy graphics, retro computing — pick the format that matches your output requirement.

Advantages of HEIF

  • ✓HEIF uses lossy compression tailored for Modern photography, iOS/macOS workflows, efficient storage and sharing.
  • ✓HEIF is supported natively on virtually every device, browser, and operating system.
  • ✓HEIF files are compact and quick to transfer, even over slow connections.
  • ✓HEIF integrates seamlessly with all major photo editing tools and workflows.

Advantages of PCX

  • ✓The lossless nature of PCX means file sizes stay reasonable while handling Legacy graphics, retro computing efficiently.
  • ✓From mobile devices to enterprise servers, PCX is recognized and supported everywhere.
  • ✓The trade-off for PCX's perfection is larger files — but for archival work, it is worth every megabyte.
  • ✓PCX is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Troubleshooting HEIF to PCX Conversion

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