About us

What is PDFTools?

PDFTools is a collection of free online tools for everyday PDF tasks: combining and splitting documents, reducing file size, converting to and from Office formats and images, adding signatures, watermarks and page numbers, and protecting sensitive documents.

Our approach

  • Process in the browser whenever it is technically possible, so files stay on your device.
  • Use proven open-source engines (such as pdf-lib, PDF.js, qpdf, Ghostscript, LibreOffice and Tesseract) on our servers when a task needs them.
  • Be clear about where each file is processed and how long it is kept.
  • Be honest about limitations instead of overpromising.
