About PDF Signing

This tool lets you add a visual signature to your PDF documents:

  • Draw your signature with mouse or touchscreen
  • Type your name in a signature font
  • Upload an existing signature image
  • Choose where to place the signature on the page
Note: This tool adds a visual signature stamp to the PDF. It does not add a cryptographic digital signature.
Tips
  • Use a white background for a clean look
  • Draw slowly for smoother lines
  • For uploaded images, use PNG with transparent background for best results
  • Medium size works best for most documents
