Use Cases

Frequently Asked Questions

Is my PDF file kept private?

Yes, completely. The tool runs entirely in your browser using JavaScript and the PDF-Lib library. Your file is never uploaded to any server.

What is the maximum file size?

There is no strict limit — it depends on your device's available memory. Files up to 100MB typically work well in modern browsers.

Can I start page numbers from a number other than 1?

Yes. Set the 'Start Number' field to any value — useful for documents that continue from a previous file.

Will adding page numbers change the existing content?

No. Page numbers are added as a new layer on top of existing content. The original text, images, and layout remain unchanged.

Can I skip adding a number to the first page?

Yes. Enable 'Skip First Page' to leave your cover or title page unnumbered.

Does it work with password-protected PDFs?

No. Password-protected PDFs cannot be modified. Remove password protection first.
