Quick answer: how do I add page numbers to a PDF?

Open the PDFTeq Page Number tool, select your PDF, choose a position (e.g. Bottom Center), pick a start page if you want to skip a cover page, set a format like Page {n} of {total}, and click Add Page Numbers. The file downloads instantly — nothing is uploaded to a server.

Submitting a legal brief, a thesis, or a corporate report without page numbers reads as unfinished. Most people try to fix this by converting the PDF back to Word, adding numbers, and re-exporting — which routinely breaks tables, fonts, and layout. This guide covers a faster way that doesn't touch the rest of your document.

Why processing happens in your browser, not on a server

Most free PDF tools — including several of the largest ones — upload your file to their servers and delete it after roughly an hour. That's a reasonable privacy practice, but it still means your document leaves your device at some point.

PDFTeq's page-numbering tool uses pdf-lib, a JavaScript library that runs the entire process inside your browser's memory. There's no upload step to skip — there simply isn't one in the code.

Verify it yourself: open your browser's developer tools (F12), click the Network tab, then number a PDF. You won't see a request carrying your file's contents anywhere — that's the difference between "we say it's private" and something you can check.

Step-by-step: add page numbers to a PDF

  1. Open the tool and select your file

    Go to Add Page Numbers and drag your PDF in, or click to browse.

  2. Choose position and font size

    Bottom Center, Top Center, Bottom Right, or Top Right — plus Small, Medium, or Large text.

  3. Set a start page (optional)

    Enter 2 to leave a cover page unnumbered — numbering restarts at 1 from the page you choose.

  4. Set a format and process

    Use Page {n} of {total}, plain {n}, or a prefix like CASE-{n}, then click Add Page Numbers to download instantly.

Page numbering vs. Bates numbering — what's the real difference?

These two get confused often, so it's worth being precise:

  • Page numbering counts pages within one document, usually for readability — "Page 3 of 12".
  • Bates numbering is a legal convention for stamping a unique, sequential identifier across an entire set of documents in a case (often with a fixed prefix and zero-padded digits, e.g. SMITH000001), so any page can be located by its stamp alone regardless of which document it came from.

PDFTeq's format field lets you add a prefix to a sequential number (CASE-{n}), which covers simple single-document exhibit stamping. It does not currently batch-number across multiple files with a shared running count the way dedicated legal e-discovery software does — if you need true cross-document Bates stamping for a large case file set, that's a gap worth knowing about upfront rather than discovering later.

Common questions this guide's format field answers

Skip the cover page

Set "Start numbering from page" to 2 (or any page) — earlier pages stay blank, numbering restarts at 1.

Font size

Small, Medium, or Large — chosen before processing, applied to every stamped page.

Custom prefixes

EXHIBIT-A-{n} or any text you want ahead of the running number.

"Page X of Y" format

Type Page {n} of {total} — {total} reflects only the pages actually being numbered, not the whole file, if you've set a start page.

PDFTeq vs. other free options

Aspect PDFTeq Adobe Acrobat Online Most cloud tools
Price Free Requires sign-in; paid Pro trial for editing Usually free with limits
Where processing happens Your browser (verifiable) Adobe's servers Provider's servers, auto-deleted after ~1 hour
Account required No Yes Varies
Custom start page Yes Yes Varies by provider
Multiple files at once Not yet — one file at a time Yes Often yes

We're not going to pretend we match every provider's batch-processing feature set — if you need to number a large batch of files right now, a tool with multi-file support will save you time until we add it.

Pro tip

Numbering a set of reports you're about to combine? Use Merge PDF first, then number the merged file — that way {total} reflects the full combined page count, not just one section.

Frequently asked questions

Yes. Set "Start numbering from page" to 2 (or any page). Earlier pages stay blank; numbering restarts at 1 from your chosen page.

Page numbering counts pages within one document. Bates numbering stamps a unique sequential ID across an entire multi-document case file. PDFTeq supports prefixed sequential numbering within a single document, not batch cross-document Bates stamping.

The file is processed locally in your browser and isn't uploaded anywhere, which avoids the data-retention questions that come with server-based tools. That said, if your organization has formal compliance requirements (like HIPAA) for handling regulated documents, check with your compliance team — running a tool locally is one factor, not a certification.

No. The tool draws text as a vector layer at a calculated position; it doesn't re-render, rasterize, or recompress your existing pages.

Not yet. Remove the password using a PDF reader that supports decryption, then number the unlocked file.
