ℹ️ Important Notes

  • • This tool creates a **simulated ARW file** — a TIFF-based container with Sony-like metadata and your image embedded losslessly.
  • • True ARW is a proprietary Sony RAW format from camera sensors (unprocessed Bayer data). This conversion embeds your processed image into a compatible wrapper.
  • • Great for archiving, metadata preservation, or testing Sony workflow compatibility (Adobe, Capture One, etc.).
  • • 100% happens in your browser — no upload to servers, fully private & secure.
  • • File size may be larger (lossless compression used where possible).
