Frequently Asked Questions

Is it safe to sign a PDF in my browser?

Absolutely. FlowTools processes everything locally in your browser. Your PDF never gets uploaded to any server.

Can I use my own signature image?

Yes. You can upload a transparent PNG of your signature, or draw one using our built-in signature pad.

Will the signature be permanent on the PDF?

Yes. The exported PDF has your overlays flattened directly into the document.
