How to Convert a Screenshot to PDF on Mac (3 Easy Ways, 2026)

PNG is great for chat apps; PDF is better for everything else that matters — printing, archiving, combining multiple captures into one document, and keeping screenshots readable at any zoom level. The short answer: open the screenshot in Preview and use File → Export as PDF, or press ⌘+P and choose Save as PDF. Both take under ten seconds.

Here are all three methods, plus how to merge many screenshots into a single PDF and how to turn an entire web page into a paginated PDF.

Method 1: Preview — Export as PDF

1. Open the screenshot in Preview (double-click the PNG on your Desktop).
2. Choose File → Export as PDF…
3. Name the file and pick a folder → Save.

That's it — pixel-identical PDF, same dimensions as the original image. Use this for single screenshots you need to file, print or email.

Method 2: The Print Dialog → Save as PDF

The macOS print dialog can turn any printable view into a PDF — screenshots included:

1. Open the screenshot in Preview (or any viewer).
2. Press ⌘+P to open the print dialog.
3. Click the PDF dropdown in the bottom-left corner.
4. Choose Save as PDF.

Why bother with this route? The PDF dropdown also offers Save as PostScript and direct handoff to Mail or Notes, so it doubles as a quick export hub. (If you need a password-protected PDF, that's a separate step in Preview: File → Export, then check Encrypt — the print dialog itself doesn't do encryption.)

Method 3: Snappix — Export Captures as PDF in One Click

Both built-in routes start from a file that's already on disk. Snappix shortens the path:

1. Capture any region, window or full-page scrolling shot with Snappix.
2. Annotate if needed — arrows, highlights, smart-blur for private info.
3. Export → PDF directly from the editor. Done.

No Preview round-trip, no temp files. And the scrolling-capture-to-PDF combo is the standout: a long web page becomes a properly paginated PDF you can print or share as a document — something a single tall PNG can't do. Batch conversions of existing image files are covered below.

Bonus: Merge Several Screenshots into One PDF

Need ten screenshots in a single document? Preview does it without extra software:

1. Open the first screenshot in Preview.
2. Open the thumbnails sidebar (View → Thumbnails).
3. Drag the other screenshots into the sidebar, in order (each becomes a page).
4. File → Export as PDF… — one PDF, multiple pages.

Rearranging pages is drag-and-drop in the same sidebar, and you can delete pages before exporting.

Bonus 2: Convert Image Files to PDF or Another Format in Bulk

If you already have a folder of PNGs (or want JPG/WebP instead of PDF), you don't need to open each one. The free online image converter on this site converts up to 10 images at a time — PNG, JPG and WebP — entirely in your browser, with no uploads. It pairs well with PDF export when you need different formats for different audiences.

Snappix exports any capture — region, window or full-page scrolling shot — as PNG, JPG, WebP or PDF straight from the editor, with annotation and smart blur built in before you export.
