How to

Convert PNG images to JPG

Open the PNG in Preview, choose File → Export, and pick JPEG with a quality you like. For many at once, sips converts every PNG in a folder, and -s formatOptions sets the JPEG quality.

Without Terminal

  1. Open the PNG in Preview.
  2. File → Export…
  3. Choose JPEG, set Quality, and Save.

In one command

Convert every PNG in the folder to a JPG at quality 85:

for f in *.png; do sips -s format jpeg -s formatOptions 85 "$f" --out "${f%.*}.jpg"; done

JPEG has no transparency: a PNG with a see-through background comes out with a solid one.

Or just ask Titan
