How to convert DNG to AVIF with FileFlip

  1. Select the DNG files

    In Finder or on the Desktop. One file, or a whole folder with ⌘ A.

  2. Press ⌥ F

    FileFlip opens next to the selection and lists the formats it can make from DNG. Type “AVIF” to jump to it.

  3. 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.

DNG 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 DNG if you may want to edit it later.

Questions about DNG and AVIF

Does converting DNG to AVIF lose quality?

AVIF can store the image either lossy or lossless.

Can I convert many DNG files at once?

Yes. Select them all in Finder, press ⌥ F and choose AVIF. Progress moves to the menu bar, so you can close the panel and keep working.

Should I keep the DNG file?

Yes. The raw file holds more information than any finished image, so keep it if you may want to edit the photo again.

Where is the AVIF file saved?

Next to the original, with the same name and the .avif extension. The DNG file isn’t changed. In Settings you can choose a different folder instead.

Can I convert AVIF back to DNG?

No. FileFlip opens DNG files but doesn’t save them.

Are my files uploaded anywhere?

No. FileFlip converts files on your Mac and works with the internet turned off.

Convert a whole shoot at once
