Frequently asked questions

Is an electronic signature legally valid?

In many countries a simple electronic signature like this is accepted for everyday agreements, but some documents require a qualified or certified digital signature. Check the requirements for your document.

What if my PDF has no fillable fields?

You can still fill it in: use “Add text” to type anywhere on the page, “Check” for tick boxes, and “Signature” to sign.

Can I type in my own language?

Yes. Latin, Cyrillic, Greek and Vietnamese characters are all supported, in text fields and added text.

Are my files uploaded to a server?

No. This tool runs entirely in your web browser, so your files never leave your device. That makes it safe for contracts, invoices and other private documents.
