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