Preview on the Mac is great for viewing and light markup, but it has no built-in way to stamp a running page number onto every page of a PDF. That leaves people hunting for an Automator workflow, a paid app, or a print-to-PDF trick, when the job takes seconds in the browser. Open FixTools in Safari or Chrome on your Mac, choose the PDF, pick where the numbers sit and which format you want, and download the numbered file. The numbering runs locally with pdf-lib, so nothing is uploaded and no App Store purchase is involved. It works on any macOS version with a current browser, whether you are on an Intel or Apple silicon Mac, and the numbered file drops straight into your Downloads folder. For the everyday task of numbering a report, a thesis chapter, or a set of handouts, it is faster than wrestling with Preview or Automator.

Preview is built around viewing, annotating, and simple page management such as rotating or deleting pages. It has no feature for drawing an automatic, incrementing page number onto each page, because that is closer to a document-generation task than to markup. People often try to fake it by typing a number on each page by hand, which is slow and error prone, or by building an Automator or Shortcuts workflow that is fiddly to set up for a one-off job.
FixTools handles the exact task Preview leaves out. It loads the PDF, walks through every page, and draws the running number in the position and format you pick, then hands the file back. Because it runs in the browser with pdf-lib, you get that capability without installing anything or sending your file to a server. When you also need to rotate, merge, or split pages, macOS and the other FixTools utilities cover those, so you can keep Preview for viewing and reach for the web tool for numbering.
Open the tool in Safari or Chrome, upload your PDF, choose a bottom position and number format, then click Add Page Numbers and save the file to your Downloads folder.

Common situations where this approach makes a real difference:
Thesis chapters
A postgraduate numbers a combined thesis PDF on their MacBook before sending it to a supervisor.
Board papers
An assistant numbers a pack of board documents on an iMac so directors can reference pages by number.
Course handouts
A lecturer numbers a printed reading pack on a Mac so students can find sections quickly.
Legal bundle
A paralegal numbers the pages of a case bundle so everyone in a meeting is looking at the same page.
Get better results with these expert suggestions:
Merge before numbering
If your document is several separate PDFs, merge them first so the numbering runs across the whole set in order.
Choose "Page 1 of N" for long packs
On a long document, showing the total makes it obvious when a printed page is missing.
Check placement in Preview
Open the numbered file in Preview afterwards to confirm the numbers sit where you expected.
Keep an unnumbered master
Save the original in Finder so you can renumber if the page order changes later.
