PDFVibe Page Numbers PDF lets you add professional, customizable page numbers to any PDF document directly in your browser — no software installation, no cloud uploads, and no account required. Whether you're preparing a thesis for university submission, organizing a legal brief for court filing, numbering pages in a business proposal, or adding pagination to a printed manual, PDFVibe handles it with full customization options. Choose where your page numbers appear — bottom center, bottom left, bottom right, top center, top left, or top right. Select your numbering format — standard Arabic numerals (1, 2, 3), Roman numerals (i, ii, iii), or alphabetical (a, b, c). Customize the font, size, and color to match your document's style. Set a custom starting number if your PDF is part of a larger document, and optionally skip the first page to leave cover pages unnumbered. All processing happens 100% locally in your browser using WebAssembly, meaning your documents — which may contain confidential legal filings, proprietary business data, or sensitive personal information — never leave your device. Unlike Adobe Acrobat Pro ($240+/year) or other paid tools, PDFVibe adds page numbers completely free with no limits on file size, page count, or usage frequency. The live preview lets you see exactly how your page numbers will appear before applying, and the instant download delivers your paginated document in seconds.
