CR3 File Format files belong to the camera raw family and use the .cr3 extension.

What to know about CR3
File structure
CR3 has format-specific rules for storing image, document or media data.
Quality
Conversion can change compression, colour, metadata, resolution or editability.
Compatibility
Support for CR3 varies between browsers, operating systems and editing applications.
Original files
Keep the original CR3 when future editing or maximum retained information matters.
How CR3 conversion works
Converting CR3 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 CR3 as an input and converts it to supported outputs.
CR3 compatibility and software support
Check that the receiving browser, app or service supports CR3 before choosing it for delivery.
A JPG or PNG copy is often useful when broad image compatibility is the priority.
