How to convert JPEG to AVIF with FileFlip

  1. Select the JPEG 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 JPEG. 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.

JPEG and AVIF

JPEG is lossy and has no transparency, so it’s a poor fit for graphics, screenshots or files you’ll keep editing. AVIF makes some of the smallest image files available, which is ideal for websites.
