Convert AVIF to JPG on Mac Free — Preview and Browser Methods

macOS handles AVIF better than Windows — Preview on macOS Ventura and later can open AVIF files natively. But if you're on an older macOS version, or need to convert in bulk, or want a simpler workflow, there's a faster path.

Which macOS Versions Support AVIF?

AVIF support arrived in macOS Ventura (13.0, released 2022). On Ventura and later, Preview can open .avif files directly.

On macOS Monterey (12), Big Sur (11), Catalina (10.15), or older, Preview will show an error or refuse to open the file. In those cases, use the browser method.

Even on Ventura+, the browser converter is faster for batch jobs and doesn't require any extra steps.

Method 1: Convert Using Preview on macOS Ventura+

1. Double-click the .avif file — it should open in Preview
2. Go to File > Export
3. Choose JPEG from the Format dropdown
4. Adjust the quality slider if needed (drag right for higher quality)
5. Click Save

Preview's export quality defaults to around 85%, which is fine for general use. Increase to 95% if you need maximum quality.

Method 2: Convert in Browser (Works on Any macOS Version)

Open the free AVIF to JPG converter in Chrome, Safari, or Firefox:

1. Drag your .avif file or files into the converter
2. Adjust quality (default 90 works well)
3. Download the JPG

This works on any Mac regardless of macOS version. Safari on macOS Big Sur and later supports AVIF rendering, so the converter will work in Safari too.

Converting Multiple AVIF Files on Mac

For batch conversion, the browser tool is faster than Preview. Drag a whole folder's worth of AVIF files into the converter at once, then download as ZIP. Preview requires one export at a time — possible but tedious with many files.

If you need to convert hundreds of files regularly, consider using the Automator app (built into macOS) with a "Preview" action to batch process, though setup takes a few minutes.

Frequently Asked Questions

Can I open AVIF in Photos on Mac?

Apple Photos on macOS Ventura and later can import and display AVIF files. For export to JPG, use File > Export > Export Photo and choose JPEG.

Does Preview on older Macs support AVIF?

No. AVIF support in Preview requires macOS Ventura (13.0) or later. Use the browser converter on older macOS versions.

Will converting AVIF to JPG in Preview reduce quality?

Slightly, since JPG is lossy. Set the export quality to 90-95% in Preview's export dialog for best results.
