JPEG Network Graphics (JNG) is a hybrid format using JPEG-compressed image data with optional PNG-compressed alpha channel.

When Should You Use PCX vs JNG?

Use PCX When...

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

Use JNG When...

Reach for JNG when your priority is legacy web animation, lossy image sequences — its efficient compression makes sharing fast and storage minimal.

PCX vs JNG: Key Differences

  • •The core technical difference: PCX relies on lossless compression whereas JNG uses lossy compression.
  • •Moving from PCX (lossy) to JNG (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
  • •How transparency is handled: JNG does not support alpha channels — transparent areas in the source will become opaque.
  • •PCX files are typically Moderate, similar to uncompressed formats while JNG files range Smaller than MNG for photos
  • •Primary audience: PCX is built for legacy graphics, retro computing scenarios, while JNG focuses on legacy web animation, lossy image sequences — pick the format that matches your output requirement.

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.

Advantages of JNG

  • ✓JNG uses lossy compression tailored for Legacy web animation, lossy image sequences.
  • ✓JNG is supported natively on virtually every device, browser, and operating system.
  • ✓JNG files are compact and quick to transfer, even over slow connections.
  • ✓JNG integrates seamlessly with all major web development tools and workflows.

Troubleshooting PCX to JNG Conversion

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