PDF Page Number Addition
Add text or vector page numbers to the local PDF page, with support for page number formats, positions, and page ranges.
How to add page numbers to PDF
PDF page-number addition processes input only in the current browser; it does not upload, connect to the internet, or save user data.
Input content
Select PDF, starting page number, page-number format, position, and page range.
Select a processing method
Generate a page-number overlay and reopen the output PDF to verify the page count and representative page.
Check and export
View the page-number preview and download the new PDF; the original file will not be modified.
Limitations and Notes
- Only adds visible page numbers; it does not modify the original text structure or process digital signatures.
- Re-saving may invalidate the digital signature; verify the page number placement in the target reader.
- The tool only provides locally processed results; important configurations, secrets, documents, and published content must still be reviewed in the target environment.
FAQ
Will the input be uploaded to a server?
No. The page only uses browser memory, the local file API, and local resources already provided with the site.
Will adding page numbers overwrite the body text?
The tool draws an overlay at the selected position; use the preview and page ranges to avoid the body text area.
Why do the results still require manual review?
Edge-case syntax, regional standards, third-party readers, and target runtime environments may differ; the tool does not replace final validation.
