No uploads. No accounts. No watermark on the output. Filoraio stamps page numbers exactly where you want them — five number formats, custom 'Page N of total' templates, skip-first-N for cover sheets, and a live preview so you see the result before you download.
Filoraio runs the merge directly inside your browser using a small WebAssembly engine. Nothing is uploaded, nothing is queued, and you can verify it yourself — open your browser’s DevTools, switch to the Network tab, and watch it stay quiet.
They’re read into your browser’s memory through a standard file picker.
The merge runs locally — no request leaves your device while it processes.
The combined PDF lands in your downloads folder, the same way any other download would.
No upload bar, no progress spinner waiting on a server. Works offline once the page is loaded.
From upload to numbered download in under a minute. The live preview means you can experiment with positions and formats freely — every change shows up immediately on the actual first-numbered page.
Drag a PDF onto the picker or click to choose one. The file stays in this tab — no upload, no quota, no account.
Pick a number format (1, 2, 3 / i, ii, iii / Page 1 of N). Choose a position from the 9-anchor grid. Set the starting number, skip-first count (for cover sheets), font, and size. The preview updates as you adjust each setting.
Click Add page numbers. The numbered PDF assembles locally and saves to your device — no watermark, no expiry, no account needed to download again later.
Anywhere a PDF needs page numbers added after the fact — because the source didn't have them, or because the page count changed after a merge — this is the tool you reach for.
Add Arabic numerals to the body of a thesis while keeping the abstract and acknowledgements unnumbered (skip-first), and use Roman numerals on the front matter as separate sections require.
Bates-number exhibit bundles for litigation: pick the letter-prefix template (e.g. 'EX-{N}'), set the starting number to match continuing exhibit sequences, and place at bottom-right where every Bates stamp is expected.
Number manuscript pages after combining multiple chapters, where individual chapter files were paginated independently. One unified sequence across the whole manuscript.
Add 'Page N of total' to staff handbooks and policy documents so readers and reviewers can reference specific pages unambiguously — and so missing pages are obvious.
Add discreet numbers to portfolio pages or proposal documents using the serif font option at small size in the bottom-corner — visible enough to navigate, invisible enough not to dominate.
Number disclosure packets and offering memoranda where every page needs to be uniquely identifiable for compliance — and where the cover sheet shouldn't be numbered as page 1.
Four common reasons people search for a way to add page numbers to a PDF — and the exact workflow each one collapses into.
You combined three PDFs and each chapter still says 'Page 1' at the bottom. The old numbers are baked into the page images, but our numbers go on top at the position you choose — pick bottom-right (away from the embedded numbers) and you get a unified sequence across the whole document.
Your thesis has a 2-page cover + 4-page TOC, and academic style requires the body to start numbering at page 1, not page 7. Set skip-first to 6, start at 1, and the body pages get clean numbering with the front matter untouched.
The opposing counsel needs exhibits Bates-numbered starting at EX-127 (continuing from a previous bundle). Use the template format 'EX-{N}', set the starting number to 127, and the bundle stamps in sequence at the bottom-right corner where Bates numbers are standard.
Your 80-page report needs the readers to know how far through they are. Pick the template format 'Page {N} of {total}', set the position to bottom-center, and every page shows 'Page 12 of 80' style numbering — the {total} token resolves automatically.
Four small habits that turn a quick number stamp into a polished result — especially on documents with existing page numbers or unusual layouts.
If your source already has page numbers (e.g. 'Page 1' baked into the layout), our new numbers will overlap if you stamp in the same position. Pick the opposite corner — if existing numbers are bottom-center, use bottom-right or top-right for the new sequence.
Academic and book conventions number front matter (TOC, foreword, acknowledgements) with Roman numerals and the main body with Arabic. Run this tool twice: once with Roman numerals on the front section using a page-range filter, once with Arabic on the body using skip-first.
When stitching parts of a long document together, set the start number to one past where the previous part ended. Combined with the page range filter, you can keep a multi-part document's pagination perfectly continuous across separate files.
If your document has a coloured page border or thick design frame, the default 0.5" margin may put the number inside it where it's unreadable. Use the margin-offset slider to push the number further from the page edge into a clear zone — typically 12–24pt extra is enough.

Quick answers to the things people ask most often before using this tool.
Yes. No account, no email, no daily quota, and no watermark on the numbered output. The page is supported by ads — never the file you download. Number as many PDFs as you need.
No. The numbering runs entirely on your device using an open-source PDF engine. The PDF never leaves the browser tab — which is why this works on confidential documents.
Five: Arabic (1, 2, 3 — the default), lower-case Roman (i, ii, iii), upper-case Roman (I, II, III), lower-case letters (a, b, c), upper-case letters (A, B, C), and a custom template where you write any text using {N} for the page number and {total} for the total count (e.g. 'Page {N} of {total}', 'EX-{N}', '— {N} —').
Pick the template format (the last option in the format picker), then enter 'Page {N} of {total}' in the template field. The {N} is replaced with each page's number, and {total} is replaced with the total count of numbered pages. The live preview shows the result immediately.
Use the 'Skip first' field. Set it to the number of pages at the start that shouldn't be numbered (e.g. 1 for a cover sheet alone, 3 for a cover + 2-page TOC). Those pages download unchanged; numbering starts on the page after.
Use the 'Start at' field. Set it to whatever number you want the first numbered page to display (e.g. 100 if continuing from a previous bundle, 5 if pages 1–4 came from another document). The numbering continues sequentially from there.
Yes. Switch to 'Specific pages' under the Numbering range section and enter ranges like '1-5, 8, 12-20'. Only those pages get numbers; the rest download unchanged. Combined with skip-first, you can fully control where numbering appears.
Yes — use the template format with a prefix like 'EX-{N}' or 'BATES-{N}'. Set the starting number to match where your Bates sequence continues from. Choose the bottom-right anchor (the standard Bates position). Re-run on subsequent exhibit bundles with the next starting number.
Wherever you click on the 9-position grid (top/middle/bottom × left/center/right). The default 0.5" margin gives standard breathing room from page edges; the margin-offset slider lets you push the numbers further in when needed (e.g. to clear a coloured page border).
Yes. Open this page in Safari (iOS) or Chrome (Android), drop your PDF, configure the numbering, and tap Add page numbers. The numbered file saves directly to Files (iOS) or Downloads (Android). The whole interface is touch-friendly.
Our numbers overlay on top of whatever's already on the page. If the existing numbers are in the bottom-center, pick the bottom-right or top-right anchor for the new sequence to avoid overlap. We don't modify the original content — only add new content on top.
Filoraio handles owner-restricted PDFs (printing/copying locks) automatically — restrictions come off as part of the numbering process. For PDFs with user passwords (encryption requiring a password to open), unlock the file first with our Unlock PDF tool, then number the unlocked output here.
Yes — and in Preview (Mac), Foxit, Chrome's built-in PDF viewer, every browser, and every mobile PDF reader. The output is a standard PDF 1.7 file with no Filoraio-specific structure. Numbers are added as standard PDF text using one of three universal fonts (Helvetica, Times, Courier).
There's no hard cap. The numbering runs in your browser's memory — the practical limit is your device's available RAM. Most browsers handle 100+ MB PDFs without trouble. Long documents (500+ pages) take a few seconds longer to render the live preview but apply numbers quickly.
Tools picked because they pair naturally with the one above — the next step in a typical PDF workflow.
