Frequently Asked Questions (FAQ)
Does this tool support mobile devices?
Yes! Our signature pad is fully optimized for touch screens. You can easily open this page on your smartphone or tablet and use your finger or a stylus to draw a highly accurate signature.

No. When you draw your signature on the pad, our algorithm converts the background to transparent. When embedded, only the ink lines are placed on the PDF, ensuring your underlying document text remains perfectly visible.
