How local processing works

The browser adds transparent text drawing commands to every existing page and saves a new PDF.

  2. Review the available settings and page order.
  3. Process locally, inspect the result, and download it.

Important limitations

Standard embedded text supports common Latin characters. A watermark discourages misuse but is not access control and may be removable by a PDF editor.

Private by design

Your files stay in this browser. The tool does not upload the source or output to our servers.
