Need a PNG for a logo, icon, or sharper edges? On macOS, you can convert JPG/JPEG to PNG using built-in tools like Preview, Finder Quick Actions, or Automator—and you can also convert online if you don’t want to use Mac apps. Preview converts via File > Export and supports batch conversion in one window.
Fastest ways to convert JPG to PNG on Mac (no installs):
- One image: Preview → File > Export… → Format: PNG → Save
- Many images (fast): Finder → select files → right-click → Quick Actions → Convert Image → PNG
- Repeat often: Use Automator to create a Quick Action / Folder Action that converts to PNG (great for daily workflows).
Which method should you use?
- Use Preview when you’re converting a few files and want a simple Export flow.
- Use Quick Actions when you want the fastest batch conversion right from Finder.
- Use Automator when you need a repeatable workflow (one-click or drop into folder automation).
Method 1 — Convert JPG to PNG in Preview (single image)
Steps (copy):
- Open the JPG in Preview.
- Apple Support
- Open the Format menu and choose PNG.
- Pick a save location and click Save.
Tip box (copy):
If you don’t see the format you want, hold Option while opening the Format menu to reveal additional formats.
Method 2 — Batch convert JPG to PNG
Steps (copy):
- In Finder, select one or more JPG files.
- Right-click → Quick Actions → Convert Image.
- Choose PNG and run the conversion.
When to choose this (copy):
This is usually the quickest batch method because it works directly from Finder (no need to open Preview).
Method 3 — Automator Quick Action
If you convert images frequently, Automator is the best set it once option. You’ll create a Quick Action that shows up in Finder, so you can select JPG files and convert them whenever you need.
Open Automator → New Document → Quick Action.
- Set workflow input to image files (Finder).
- Add Change Type of Images and set output to PNG.
- Save as Convert to PNG.
Method 4 — Automator Folder Action
For repeat workflows (blog uploads, ecommerce, design assets), a Folder Action can be faster than clicking Quick Actions every time, drop files into a folder and let Automator convert automatically.
