Frequently Asked Questions

How do I sign a PDF for free?

Add the PDF above, click Add signature and draw or type it, move it where it belongs, then click Sign & Download PDF. There is no account and no limit.

Can I sign on my phone?

Yes. Draw your signature with your finger in the box, then drag it into place on the page.

Is this a legally valid signature?

It adds a picture of your signature, like signing on paper and scanning the page. Many everyday documents accept this. Some contracts require a certified digital signature issued by an approved provider; this tool does not create one.

Is my signature saved anywhere?

No. The signature exists only in this browser tab while you work and is gone when you close it.
