Pro Tips for Signing PDFs
- Use the Coordinate System: Our tool uses a precise coordinate system (X for horizontal, Y for vertical) to help you place your signature in the exact same spot on every document.
- Type vs. Draw: If you are on a desktop, typing your signature often looks cleaner. If you are on a mobile device or tablet, drawing your signature with a stylus or finger provides a more authentic look.
- Protect Your Signed Files: Once your document is signed, use our PDF Password Protect tool to prevent unauthorized editing of your signed file.
