FAQ
Frequently asked questions
Are my files uploaded?
No. The conversion runs inside your browser using WebAssembly, so your files never leave your device. Nothing is sent to our servers.
Is it safe to sign contracts here?
The PDF and your signature stay in your browser. Nothing is uploaded, stored or sent anywhere, so there is no copy of your signature on a server.
Is this a legally binding e-signature?
In many countries a signature image on a document is accepted for everyday agreements, but rules vary. For documents that need a certified digital signature, use a dedicated e-signature service.
Can I sign more than one page?
Yes. Move to another page and click Add signature again. You can place it as many times as you need.
