Step-by-step instructions

Method 1: Browser converter (most convenient)
Go to formatdrop.com → Image Converter. Drop your AVIF file. Select JPG as output. Set quality (85-90% for photos). Download. The converter runs in your browser and handles AVIF decoding locally.

Method 2: macOS Preview (Mac, free)
macOS Ventura (13+) supports AVIF in Preview. Open the AVIF file in Preview → File → Export → select JPEG format → set Quality → Save. If Preview shows an error (older macOS): use the browser converter instead.

Method 3: GIMP (free, all platforms)
GIMP 2.10.22+ supports AVIF via the libavif plugin. Open the AVIF in GIMP → File → Export As → set filename with .jpg extension → Export → set JPEG quality → Export. If GIMP shows 'unknown file format': update GIMP or install the libavif-gdk-pixbuf package.

Method 4: FFmpeg
ffmpeg -i input.avif output.jpg. For specific quality: ffmpeg -i input.avif -q:v 2 output.jpg (q:v 1-31, lower = better). FFmpeg requires libavif support compiled in. Check: ffmpeg -codecs | grep avif
Why convert AVIF to JPG?
AVIF achieves 50-60% smaller files than JPG at equivalent quality, making it excellent for web delivery. But AVIF's newness means most non-browser software (Photoshop before 2022, older Windows Photo Viewer, most email clients, print software) can't open it. Converting AVIF to JPG makes the image universally accessible at the cost of a larger file size.
Your files never leave your device
FormatDrop runs the conversion engine entirely inside your browser using WebAssembly. No file upload. No server. Nothing stored. You can verify this by opening DevTools → Network tab and watching: zero upload requests.
