How to Convert PNG to PDF on Mac in 2026

Mac makes it surprisingly easy to convert PNG images to PDF — and you don't need to buy any software. Whether you want to use the built-in Preview app, a quick drag-and-drop method, or a free online converter for batch conversions, this guide covers all the best options for macOS users.

Method 1: Using Mac Preview (Built-in, Free)

Preview is macOS's built-in image viewer and it has powerful PDF export capabilities.

Convert a Single PNG to PDF

1. Double-click your PNG file to open it in Preview
2. Go to File → Export as PDF
3. Choose a name and location, then click Save

That's it — your PNG is now a PDF!

Convert Multiple PNGs into One PDF

1. Select all your PNG files in Finder (Cmd+A or Cmd+click)
2. Right-click → Open With → Preview
3. All images open in Preview's sidebar
4. Go to File → Print (Cmd+P)
5. Click the PDF dropdown at the bottom left → Save as PDF
6. Name your file and click Save

Pro Tip: In Preview's sidebar, drag images to reorder them before printing to PDF. This controls the page order in the final PDF.

Method 2: Free Online Converter (Best for Batch + More Control)

For more control over page size, margins, and orientation — or to convert many PNGs at once — use a free online converter.

Step 1: Upload Your PNG Files

Step 2: Customize Your PDF

Step 3: Download Your PDF

Method 3: Drag PNG onto Safari (Quick Trick)

Here's a little-known Mac trick:

1. Open a new tab in Safari
2. Drag your PNG file from Finder directly into the Safari tab
3. The PNG opens in Safari
4. Press Cmd+P → click PDF → Save as PDF

Limitation: Only works for one image at a time and doesn't give you page size control.

Method 4: Using Automator (For Power Users)

Mac's built-in Automator app can create a workflow to batch convert PNGs to PDF with a right-click:

1. Open Automator (search in Spotlight)
2. Create a new Quick Action
3. Set "Workflow receives" to image files in Finder
4. Add action: New PDF from Images
5. Save the workflow with a name like "Convert to PDF"
6. Now right-click any PNG in Finder → Quick Actions → Convert to PDF
