PDF Page Numbers

The tool offers six preset positions: bottom-center, bottom-left, bottom-right, top-center, top-left, and top-right. Bottom-center is the default and matches the MLA, APA, and Chicago style requirements for academic papers, as well as the page-number position expected by most print-shop templates. Top-right is the standard for legal filings, because the number remains visible when pages are stapled along the left edge. You can fine-tune placement by adjusting horizontal and vertical margin values independently. Margins are expressed in points, where one point equals exactly 1/72 of an inch. A margin of 36 points places the number half an inch from the selected edge. The same margin value applies uniformly to every page, preventing numbers from drifting across the document. For two-sided printing where odd pages should have numbers on the right and even pages on the left, export two separate passes: one pass numbering odd pages with right alignment and another numbering even pages with left alignment, then use our PDF Merge tool to interleave them. Preview the position on the first page before exporting the full document to confirm the number sits precisely where you need it, well clear of any existing content near the edges.

Yes. A start-page field lets you begin numbering from page 3, page 5, or any arbitrary page offset. This directly supports the academic convention of leaving the cover page and table of contents unnumbered while still applying page numbers to the body of the document. A separate start-number field sets the label that is actually printed on the first numbered page. Set start-number to 1 and start-page to 3 to print a fresh count beginning at 1 on page 3. Set start-number to 3 on page 3 if the cover and TOC should count toward the total page tally in cross-references, while numbers appear only from page 3 onwards. Both fields accept any positive integer. For more complex front-matter — for example, lowercase Roman numerals on the table of contents section and Arabic numerals on the main body — export two separate numbered passes: apply Roman numbering to a copy of the front-matter pages, apply Arabic numbering to the body pages, then merge both parts with our PDF Merge tool. The combined result correctly presents both numbering systems without any gap or overlap. All processing happens in your browser — nothing leaves your device, so even confidential draft documents are safe to process without concern about third-party access.

Page numbers render in Helvetica by default. Helvetica is embedded in the PDF specification and supported natively by every PDF reader and printer without requiring a separately downloaded font file. The default size is 10 points, which reads cleanly on both screen and printed paper at standard sizes. You can change the point size from 6 to 24 using the size input. Smaller sizes like 8 points work for legal documents with tight margins. Larger sizes like 14 to 16 points suit presentations or documents designed for readers with low vision. You can change the color to any of the 16 standard CSS color names — black, gray, blue, red, and others — or enter a custom hex code for an exact brand match. Font family is fixed to Helvetica to keep the tool fast and the output file small. Embedding a custom font file into every page would increase the output size by hundreds of kilobytes per font. If your document uses embedded brand fonts and you need exact typographic consistency in the page numbers, use a desktop application like Adobe Acrobat Pro or Affinity Publisher for that specific requirement. For the vast majority of documents, Helvetica in black at 10 points is the correct and professional choice.

Yes. The tool works by adding a new annotation layer containing the page number stamp on top of each page. It does not modify, replace, or re-render the existing content stream. All hyperlinks in the document remain active and clickable. All interactive form fields, including text inputs, checkboxes, radio buttons, and dropdown menus, remain fully functional. Bookmarks in the document outline panel are preserved exactly as they were. Text selection works identically to the original: readers can click and drag to copy body text without inadvertently selecting the page number, which sits in a separate annotation object. Screen readers announce the body content correctly and do not read out the page number annotation unless the reader is specifically navigating annotations. Document metadata including title, author, subject, and creation date is copied to the output file without alteration. The output file size increases by approximately 1 to 3 kilobytes per page, which is negligible — the added annotation objects are very lightweight compared to image or font data. For password-protected or encrypted PDFs, remove the encryption first with our PDF Unlock tool. Page-number stamping requires write access to the page structure and cannot modify an encrypted content stream.
