Adding page numbers to a PDF online is simple with Number My Document. Add page numbers to PDF free by uploading your file, selecting a format, and downloading the result — all processed in your browser. Unlike ilovepdf, smallpdf, or PDF24, your file never leaves your device.
The tool supports every professional format: simple Arabic numbers (1, 2, 3) for basic reports; Page X of Y (Page 1 of 10) for business and academic documents; Roman numerals in lower case (i, ii, iii) or upper case (I, II, III) for thesis front matter and legal index pages; letter numbering (a, b, c) for annexure sub-sections; custom prefix formats like Department-A — Page 1 of 10; Bates-style sequential stamps like TENDER-LKO-000001; and filename tokens like {filename} — Page {page} for multi-document audit sets.
A common requirement for reports, proposals, and thesis documents is to leave the title page unnumbered. Set “Stamp from page” to 2 and “Start number” to 1. The cover page has no stamp. The second PDF page shows the number 1. This is standard for business reports, tender submissions, project files, and thesis documents worldwide.
Tools like ilovepdf, PDF24, Smallpdf, and Adobe Acrobat Online upload your PDF to their servers. For confidential documents — legal case files, salary records, financial statements, medical records, tender pricing, government submissions — this is a privacy risk. Number My Document uses PDF-lib running in your browser. Zero bytes of your document ever leave your device. You can verify this by monitoring network requests in browser developer tools while the tool processes your file.
Regular page numbering adds sequential page counts for readability. Bates numbering adds a unique identifier to each page — CASE-2026-000001 — for traceability in legal discovery, audit file sets, tender submissions, and compliance documents. Use this tool for regular numbering. Use the Bates numbering tool for structured legal and audit stamps.
Adobe Acrobat requires a $14.99/month subscription. ilovepdf and smallpdf are free but upload files to remote servers, impose file size limits in free tiers, and lack professional formats like Bates numbering and annexure stamps. PDF24 is free and partially browser-based but lacks advanced formatting. Number My Document is free, fully browser-based, unlimited, and supports every format professional users need.
