Quick Answer

Mac has a built-in way to turn a PDF page into a JPG, hidden inside Preview — but it only exports one page at a time and the menu isn't exactly obvious. If you need the whole document converted, a free browser tool does every page in one pass. Both methods below.

Method 1: Using Preview (Built Into macOS)

No extra software needed for this one — Preview ships with every Mac.

  1. Open the PDF in Preview (the default app when you double-click a PDF).
  2. Go to File → Export (not "Export as PDF" — plain "Export").
  3. In the Format dropdown, choose JPEG.
  4. Adjust the quality slider if you want, then click Save.

The catch: Preview only exports whichever page is currently visible. For a multi-page PDF, you'd repeat this for every single page, switching pages in between. Fine for a one-page document, tedious for anything longer.

Method 2: Convert Every Page at Once

For a multi-page PDF, the PDF to JPG tool handles the whole file in one pass, right in your Mac's browser — no download from the App Store.

  1. Open the tool at pdffans.com/tools/pdf-to-jpg.
  2. Drop your PDF onto the page, or click to browse for it.
  3. Pick a quality setting — 150 DPI works for most sharing, 300 DPI if you need it sharp at a larger size.
  4. Let it process — every page converts to its own JPG at once.
  5. Download the pages you need.

Since the conversion runs in the browser itself, the file never leaves your Mac — there's no upload step happening in the background.

Which Method Should You Use?

Preview is the right call for a single page — it's already installed and takes seconds. Once a PDF has more than a couple of pages, the browser tool is faster because it does the whole document in one action instead of a menu-and-export cycle repeated per page. It's also the more practical option if you want consistent output settings across every page rather than adjusting the quality slider each time.

FAQ

Why does Preview's Export option only save one page?

Preview treats the PDF like a document viewer — Export saves whatever page is on screen, not the entire file. There's no built-in "export all pages as JPG" option in Preview itself.

Can I convert a PDF to JPG on Mac without any software?

Yes, in two ways: Preview (already installed) for one page at a time, or a browser-based tool for the whole document at once.

Will the image quality suffer either way?

Not if you pick a reasonable quality setting. Preview's quality slider and the browser tool's DPI setting both control the same trade-off between file size and sharpness.

Is my file uploaded anywhere when I use the browser tool?

Not if the tool is client-side — the PDF stays on your Mac and converts locally in the browser tab.
