How to convert RAF to AVIF with FileFlip
Select the RAF files
In Finder or on the Desktop. One file, or a whole folder with ⌘ A.
Press ⌥ F
FileFlip opens next to the selection and lists the formats it can make from RAF. Type “AVIF” to jump to it.
Choose AVIF and press Return
The AVIF files appear next to the originals. To make them smaller first, press ⇥ and lower the quality or size.
RAF and AVIF
Raw files are large and most apps and websites can’t show them, so they have to be developed into a regular image before sharing. AVIF makes some of the smallest image files available, which is ideal for websites.
What changes when you convert
- AVIF can store the image either lossy or lossless.
- A raw file is unprocessed sensor data. Converting develops it into a finished image, so keep the RAF if you may want to edit it later.
