Why AVIF files are used
AV1 Image File Format files belong to the raster images family and use the .avif extension.
The most practical format depends on the software, quality, compatibility and file-size requirements of the destination workflow.
What to know about AVIF
File structure
AVIF has format-specific rules for storing image, document or media data.
Quality
Conversion can change compression, colour, metadata, resolution or editability.
Compatibility
Support for AVIF varies between browsers, operating systems and editing applications.
Original files
Keep the original AVIF when future editing or maximum retained information matters.
How AVIF conversion works
Converting AVIF 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 AVIF as an input and can also create AVIF output.
AVIF compatibility and software support
Check that the receiving browser, app or service supports AVIF before choosing it for delivery.
A JPG or PNG copy is often useful when broad image compatibility is the priority.
