How to open Camera RAW files

Requires specialist decoding. When a browser or application cannot decode the file directly, convert a copy to JPG for compatibility or PNG when transparency and lossless graphics matter.

When to use Camera RAW

  • Photo development
  • Exposure recovery
  • Archival camera originals

Best settings for Camera RAW

  • Use RAW files as camera originals for exposure recovery, white balance control, and professional photo editing.
  • Export JPG for sharing, TIFF for print or archival handoff, and WebP/AVIF for web delivery.
  • Keep the RAW original because exported formats cannot restore all sensor data later.

Compatibility checklist

  • RAW rendering depends on camera profile, white balance, and editing decisions.
  • Most upload forms and browsers do not accept RAW files directly.
  • Use dedicated photo software for color-critical RAW development.

Limits to consider

  • Rendering depends on white balance and tone choices
  • Keep the original RAW file after export

Convert Camera RAW images

Choose an output based on the destination, not just file size. Conversion runs locally in your browser whenever the required decoder is available.

Dedicated converters for this specialist format are being tested before publication. The guide is available now so you can evaluate compatibility and format tradeoffs.
