Examples

Adds centered numbers 18 points above each visible page’s bottom. Existing content is not moved; check for overlap. Existing page text is retained and checked. Signed, interactive or complex PDFs are rejected. Marks are added to all pages.

PDF input and output only. Up to 500 pages total; two-minute processing limit; 100 MiB output limit. Complex documents may fail even within these limits. Review the result before sharing.

Files and outputs stay in browser memory. Processing libraries and fonts load from Reqly; documents are not uploaded. Reset releases file references and cancels work. Downloads remain on your device.

If processing fails, try fewer files or a smaller, unencrypted PDF. The original is unchanged. No server fallback is used.
