How to batch convert HEIC to JPG on Mac

iPhones save photos as HEIC: small files, but many Windows PCs, web forms and older apps can't open them. Your Mac can convert them without paid software; the difference is how many at a time and how many clicks.

1. Finder: Convert Image

1. Select the HEIC files in Finder.
2. Control-click and choose Quick Actions › Convert Image.
3. Pick JPEG and Actual Size, then click Convert to JPEG.

The JPGs appear next to the originals. Built in since macOS 12; handy for a few dozen files.

2. Export from Preview

Open the photos together in Preview, select all thumbnails in the sidebar, choose File › Export Selected Images…, and set the format to JPEG in Options.

3. The sips command in Terminal

mkdir -p jpg && for f in *.HEIC *.heic; do [ -e "$f" ] && sips -s format jpeg "$f" --out "jpg/${f%.*}.jpg"; done

Run it inside the photo folder. Results go to a jpg subfolder and thousands of files are fine.

4. Flipic: a whole folder at once

1. Open the folder in Flipic.
2. Choose Tools › Batch Convert, or press ⇧⌘C.
3. Pick JPEG, set the quality and start.
