Skycally's page-numbering tool helps you turn raw PDF exports into properly paginated documents in seconds. Pick where the number should appear — bottom center, bottom right, bottom left, or top center — choose a font size, and set the starting number. The tool then stamps a clean Helvetica numeral on every page using pdf-lib.

All processing runs in your browser, so the original PDF never leaves your device. That makes it ideal for adding numbering to contracts, theses, manuscripts, or internal reports without exposing them to third-party servers.

Frequently Asked Questions

Can I start numbering from a number other than 1?

Yes. Set any non-negative starting number and the tool will increment from there for each subsequent page.

Can I customize the font?

The current version uses Helvetica in three preset sizes. Custom fonts and colors will arrive in a future update.

Does this work with encrypted PDFs?

Standard encrypted PDFs are loaded with the ignoreEncryption flag, so most files work, but heavily protected PDFs may fail.

Is my file uploaded anywhere?

No. The PDF is processed entirely in your browser using pdf-lib.
