What is PNG?

PNG (Portable Network Graphics) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for GIF.

What is RAF?

Fujifilm Raw Format (RAF) contains raw sensor data from Fujifilm X-Series and GFX cameras with unique X-Trans sensor processing.

When Should You Use PNG vs RAF?

Use PNG When...

Reach for PNG when your priority is graphics, logos, images requiring transparency — its uncompromising quality ensures every detail is preserved.

Use RAF When...

Reach for RAF when your priority is fujifilm photography, film simulation processing — its uncompromising quality ensures every detail is preserved.

PNG vs RAF: Key Differences

  • •PNG and RAF diverge on compression: lossless compression for the source, lossless compression for the target.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •Alpha channel support: RAF lacks transparency support.
  • •Storage footprint: 20KB to several MB for PNG vs 20-50MB per photo for RAF.
  • •Primary audience: PNG is built for graphics, logos, images requiring transparency scenarios, while RAF focuses on fujifilm photography, film simulation processing — pick the format that matches your output requirement.

Advantages of PNG

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

Troubleshooting PNG to RAF Conversion

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