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