Raw to TIFF Converter is a project I developed to convert raw camera files into TIFF format.

While there are probably a ton of perfectly fine converters out there, I preferred creating my own over searching the internet for one.

The tool is open-source and available on GitHub. Please be aware that while it has improved significantly in recent updates, it’s still recommended to maintain backups of your files as some features are not fully tested.

Supported Files

This converter supports the following RAW file formats:

  • .cr2
  • .nef
  • .arw
  • .dng
  • .raw

The converter has only been tested with .cr2 but it should theoretically support way more file types.

Technical Background

Originally, this project used Pillow for conversions, which led to quality loss and issues like unexpected horizontal flipping, probably caused by some mistake I made. Switching to rawpy and imageio improved output quality, though the code remained a bit experimental. Proceed with caution if you’re planning to use this for critical work, as quality assurance is still ongoing.

For those interested in contributing or experimenting with the tool, feel free to check out the project at its GitHub repository.
