CRW to AVIF
File Converter

CRW was one of the early raw image file formats used by Canon digital cameras. It captures all the data from the camera’s sensor without any compression or processing, preserving the maximum amount of image information for post-processing. However, this format has largely been superseded by the newer CR2 and CR3 formats, which provide more advanced features and better compression. CRW files require specialized software for viewing and editing, and they are generally larger in size compared to standard compressed image formats.

AVIF (AV1 Image File Format) is a cutting-edge image file format developed by the Alliance for Open Media, utilizing the AV1 video codec for highly efficient image compression. It supports a wide range of features including high dynamic range, wide color gamut, and 8-10 bit color depth, all while achieving significantly smaller file sizes compared to traditional formats like JPEG and PNG, though it may not be as widely supported across all platforms and software yet.
