What Add Page Numbers does

Use Add Page Numbers when you need to number appendices, scan packets, or review drafts before sending them out.

When to use it

  • Number appendices, scan packets, or review drafts before sending them out.
  • Start numbering from a custom value when a PDF is part of a larger set.
  • Place numbers where they do not cover existing footers or stamps.

How to use it

  1. Add the PDF and choose number position.
  2. Set the first number when the document should continue another sequence.
  3. Export and inspect pages with existing footer content.

What to check

  • Check pages with signatures, stamps, or dense footnotes.
  • If the PDF already has printed page numbers, make sure the new numbering does not conflict.

Data, formats, and limits

What stays on your device and what is sent

Runs in your browser. The file and result are not sent to Utilio servers.

Supported formats

Supported: PDF. Not supported: DOCX, XLSX, PPTX, JPG, PNG, HEIC, ZIP.

File limits and browser requirements

  • Up to 100 MB per PDF
  • Runs in browser memory, so very large, scanned, or image-heavy PDFs can be slow or fail on low-memory devices.
  • Encrypted or damaged PDFs may not open unless the specific tool supports that workflow.

Known limits

  • Runs in browser memory, so very large, scanned, or image-heavy PDFs can be slow or fail on low-memory devices.
  • Encrypted or damaged PDFs may not open unless the specific tool supports that workflow.

Troubleshooting

  • If the PDF does not open or processing stops, try a smaller file or close extra tabs to free browser memory.
  • If the file is password-protected or damaged, first confirm it opens in a regular PDF viewer.
  • If the file is in an unsupported format (DOCX, XLSX, PPTX, JPG, PNG, HEIC, ZIP), convert it into a supported PDF first.

Do I need an account?

Can I use it on a phone?

Yes. For large files, complex previews, or careful review, a browser on a computer is usually more comfortable.

How do I get a reliable result?

Which formats are supported?

Add Page Numbers supports PDF. It does not support DOCX, XLSX, PPTX, JPG, PNG, HEIC, ZIP.

What file size works best?

Up to 100 MB per PDF. Browser memory and device speed can still affect large files.

Why did I not get the result I expected?

Runs in browser memory, so very large, scanned, or image-heavy PDFs can be slow or fail on low-memory devices. If the result still looks wrong, try a smaller or simpler input and review the output before using it.

Does Utilio use my input or results to train AI?

No. Utilio does not use files, pasted text, settings, generated values, or results from this tool to train AI models.
