Add page numbers without converting your PDF to images

OneFileKit stamps page numbers as real PDF text objects using pdf-lib. Original page contents, dimensions and searchable text are preserved where the source PDF already supports them.

Live preview uses the same margin and position math as export so what you see closely matches the downloaded file. Viewer zoom does not change export coordinates.

We do not claim perfect compatibility with every unusual PDF feature (complex forms, rare encodings, or heavily protected documents).

Security & privacy

  • Uploads are validated by extension, MIME type and PDF structure.
  • Password-protected PDFs are rejected with a clear message when they cannot be modified safely.
  • Page ranges are validated against the real server-side page count.
  • Downloads require a secret token bound to your job.
  • Temporary files expire after a configurable retention period.
  • We do not store document text in analytics.
