About PDF Page Size Changer
Pages that are the wrong size cause real problems, from printers that crop your content to documents that mix A4 and Letter and refuse to look consistent. Sometimes you just need every page to match a standard format.
This tool changes the page size of your PDF to A4, Letter, Legal, and other common formats. You pick the target size, apply it, and download a document where the pages match the format you chose. It is free, runs in your browser without an account, and adds no watermark, so the resized file stays clean and ready to print or share without surprises.
