FAQ

What is a CR3 file?

A CR3 file is a RAW image format used by modern Canon digital cameras to store uncompressed image data directly from the camera sensor.

Can I resize my image during conversion?

Yes, you can specify an optional maximum width or height in pixels to resize the output JPEG while maintaining the aspect ratio.

How does highlight recovery work?

The highlight recovery option helps restore details in overexposed or blown-out areas of the RAW image by reconstructing highlight data.

Will the converter preserve my photo's metadata?

Yes, the tool automatically extracts and preserves image dimensions and metadata from the original CR3 file during conversion.

Is there a file size limit for the CR3 upload?

Yes, the maximum supported file size for a single CR3 RAW file is 200 MB.
