HEIF to JPG
Turn HEIF photo files into JPEG image files on your own Mac, Windows or Linux computer. Asteria is free, works offline, and never uploads your files.
How to do it
- Download Asteria and open it. It's free and needs no account.
- Drop your HEIF files onto its window, or press ⌘O (Ctrl O on Windows) to choose them. Drop as many as you like.
- Type jpgand pick Convert to JPEG. Opens everywhere; transparency turns white.
- Press ⌘↵ (Ctrl ↵ on Windows) to save. The JPG files appear next to the originals, which stay exactly as they were.
Quality: 90 = high quality, 75 = smaller file. Add it after the name, like jpg 90.
What it needs
Nothing. This conversion is built into Asteria, so it works the moment the app is open, even offline.
How it was tested
A real HEIF file was converted on macOS on Apple silicon and Linux, and the JPG that came out was opened and checked with ImageMagick identify to make sure it is what it says it is.
