How to work with PDFs using PDF Tools ​

PDF Tools is a set of 11 free PDF tools that run 100% in your browser. There are no uploads, no accounts, and no servers involved — your files are processed on your own device.

Use any tool ​

Use any tool

The flow is the same for every tool:

  1. Open PDF Tools and pick the tool you need from the grid.
  2. Add your file or files to the tool.
  3. Adjust the tool's options for what you want to do.
  4. Process the file and download the result.

Heavy files are handled in background workers, so the page stays responsive while processing runs.

Tips ​

Tips
  • Do conversions before edits. If you need a JPG as part of an edited PDF, convert it to PDF first, then use Merge or Organize on the result — each tool does one job, and chaining them in order is the simplest path.
  • Check page order after organizing. After reordering or removing pages, glance through the result before downloading — it is quicker to fix the order now than to re-run the tool.
  • Keep a copy of the original. Tools like Compress, Unlock, and Protect change the file itself. Download the result as a new file and keep your original untouched, in case you need it again.
  • Your files never leave the device. Because everything runs in the browser, you can use these tools for sensitive documents without sending them to any server.
