Automatically staple page numbers to your document effortlessly.
Whether you are preparing a legal brief, drafting an academic thesis, or compiling a dense financial report, sequential page numbering is essential for readability and referencing. PDF Toolkit's Add Page Numbers tool automatically stamps professional, easy-to-read page numbers onto every page of your PDF document. You can customize the positioning — choose from the bottom-left, top-right, bottom-center, and more — to match your document's formatting. Unlike server-based editors, all processing happens entirely on your own device using WebAssembly. This ensures that your private files remain 100% confidential and are never uploaded to the cloud. You can instantly number a 500-page document locally with zero wait time.
