Free PDF Page Numberer

How does our Add Page Numbers tool work?

Our Advanced PDF Page Numberer runs 100% offline directly in your browser. Unlike traditional online tools that require uploading your private documents to external servers, we process your files locally on your device.

• 100% Privacy Protection: Your files never leave your device. Perfect for confidential legal documents, reports, and books.
• Smart Alignment: The tool calculates the width of each text string dynamically and aligns it perfectly to the center, left, or right margins of your document.
• Lightning Fast: Because there is no uploading or downloading to a server, processing a 100-page document takes less than a second.
• No Size Limits: Free to use for unlimited documents without registration or annoying external watermarks.
