PDF Page Number

Reports, theses, contracts, and manuals often arrive as PDFs without page numbers. While adding them is essential for printing and review, launching a heavyweight PDF editor feels like overkill for such a simple task. This tool lets you upload a PDF and automatically add page numbers to every page.

You can customize the position (top or bottom, left, center, or right), font size, starting number, and choose whether to display the total page count (e.g., "1 / 10"). Select from three color options—black, dark gray, or white—to match your PDF's background and ensure readability across different document types.

Choose between Helvetica (sans-serif) and Times Roman (serif) fonts to match the tone of academic papers, professional reports, or business documents. Processing runs in the browser using pdf-lib, so you can create the numbered PDF without server-side uploading. It is useful when internal documents, papers, contracts, or manuals need clear page order before review or sharing.

For longer documents, combine this tool with [PDF Bookmark Editor](/en/pdf/pdf-bookmark-editor/) to add navigation entries. Use [PDF Header & Footer](/en/pdf/pdf-header-footer/) when the same heading, date, or label should appear on every page, and [PDF Page Label](/en/pdf/pdf-page-label/) when Roman numerals or cover-page numbering need separate labels. Before submission, [PDF Metadata Editor](/en/pdf/pdf-metadata-editor/) helps check document title and author information.
