The Secure Way to Number PDF Pages Online

Managing professional documents often requires proper organization, and one of the most essential elements of a well-organized document is pagination. Whether you are submitting a thesis, a legal contract, or a business report, page numbers make navigation easy. However, many online tools require you to upload your sensitive files to a remote server, which poses a security risk.

Why Use The PDF Mechanic?

Our Add Page Numbers tool is unique because it operates entirely client-side. This means your PDF file never leaves your computer or phone. The processing happens in your browser's memory using advanced WebAssembly technology. This ensures that your confidential data—be it financial records or personal IDs—remains 100% secure and private.

Key Features

  • 100% Free & Unlimited: No hidden costs, no watermarks, and no limits on the number of files you can process.
  • Offline Capability: Once the page loads, you can disconnect your internet, and the tool will still function perfectly.
  • Customizable Positioning: Place numbers in any corner (Top-Left, Bottom-Right, etc.) or in the center of the page.
  • Flexible Formatting: Choose from standard numbers (1, 2, 3), labeled formats (Page 1), or total count formats (Page 1 of 5).

How to Add Page Numbers on Android & PC

You don't need expensive software like Adobe Acrobat to number your PDF pages. Just follow these simple steps:

  1. Click Select PDF File and choose your document.
  2. Select the Position grid to choose where the number should appear.
  3. Choose your preferred Number Format (e.g., "1 of N").
  4. Click Add Page Numbers and download your new file instantly.

Pro Tip

Since this tool runs locally, it is incredibly fast. You can use it to add page numbers to large files without waiting for slow uploads or downloads.
