Why CR2 files are used
CR2 File Format files belong to the camera raw family and use the .cr2 extension.
The most practical format depends on the software, quality, compatibility and file-size requirements of the destination workflow.
What to know about CR2
File structure
CR2 has format-specific rules for storing image, document or media data.
Quality
Conversion can change compression, colour, metadata, resolution or editability.
Compatibility
Support for CR2 varies between browsers, operating systems and editing applications.
Original files
Keep the original CR2 when future editing or maximum retained information matters.
How CR2 conversion works
Converting CR2 decodes or renders the source and then encodes the result in the selected destination format.
Review the converted file before replacing the source because format-specific features may not transfer.
heic.now accepts CR2 as an input and converts it to supported outputs.
CR2 compatibility and software support
Check that the receiving browser, app or service supports CR2 before choosing it for delivery.
A JPG or PNG copy is often useful when broad image compatibility is the priority.
