The guide and converter lists are generated from the live HEIC.now catalog, so every conversion shown here is an available workflow.
Why CRW files are used
CRW File Format files belong to the camera raw family and use the .crw extension.
The most practical format depends on the software, quality, compatibility and file-size requirements of the destination workflow.
What to know about CRW
File structure
CRW has format-specific rules for storing image, document or media data.
Quality
Conversion can change compression, colour, metadata, resolution or editability.
Compatibility
Support for CRW varies between browsers, operating systems and editing applications.
Original files
Keep the original CRW when future editing or maximum retained information matters.
How CRW conversion works
Converting CRW 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 CRW as an input and converts it to supported outputs.
CRW compatibility and software support
Check that the receiving browser, app or service supports CRW before choosing it for delivery.
A JPG or PNG copy is often useful when broad image compatibility is the priority.
