Rawzor is a proprietary lossless image compression software which compresses camera raw images without any loss in image quality or meta-information. It is currently available only for Microsoft Windows but a Mac OS X version has been promised.[1]

Features

  • Supports all major raw formats. Complete list of supported formats and cameras is on the website.[2]
  • Typically provides between 20% and 60% space savings depending upon the raw format. This is significantly better than compression obtained by zip or rar on image files.[3][4]
  • It is completely lossless, there is absolutely no loss in image quality or meta-information. Decompression gives back the exact same original file.

Working with Rawzor compressed images

Rawzor has released a free SDK using which many image processing software provide support to open and edit Rawzor compressed images. SDK is available for 32-bit and 64-bit Windows and Linux. SDK for Mac OS X has been promised but is not available yet.

Some of the software supporting Rawzor compressed .rwz images:

  • XnView provides plugin to support Rawzor compressed images.[5]
  • Konvertor has native support for Rawzor's rwz format.[6]
  • Raw Therapee added Rawzor support starting version 2.4 on both Windows and Linux.[7]
  • ExifTool added Rawzor support in September 2008.[8]

Rawzor compressed photos have .rwz extention. For example, birthday.cr2 will after compression become birthday.cr2.rwz The naming convention also indicates that the original .cr2 file is preserved within the compressed .rwz file.

Rawzor compressed images can be decompressed to get back the image file in its original format.
