How to convert CR2 to DDS offline

Choose local CR2 image files, choose "DDS" as target image format, then click the "CONVERT OFFLINE" button to start offline conversions in bulk. File size can be up to 2GB.

This offline converter will try to use canvas in web browser to convert images first. The image format depends on whether your current web browser supports. For example: the latest Chrome browser supports AVIF images while some old versions don't. Then the offline converter will try to use JavaScript to convert images if your current web browser doesn't support the image format.

Introduction	The .CR2 file format (Canon RAW version 2) is a digital photography RAW format created by Canon. "RAW" here means that this file stores information directly coming from the sensor, almost without processing. RAW files can be seen as a digital negative format, and do not contains a "ready to view" picture, like jpeg.	The DirectDraw Surface container file format (uses the filename extension DDS), is a Microsoft format for storing data compressed with the proprietary S3 Texture Compression (S3TC) algorithm, which can be decompressed in hardware by GPUs.
