Frequently asked questions
Is this a legally binding signature?
It creates a visual signature, which is accepted for many everyday documents. Some contracts require a certified digital signature from a trust service — check what the recipient needs.
Can I put the signature on several pages?
Yes. Go to another page with the arrows and click again to place it there too.
Is Sign PDF free?
Yes. Sign PDF is free to use with no sign-up and no watermark.
Are my files uploaded to your server?

Does it work on my phone?
Yes. It works in any modern browser on Windows, Mac, Linux, Android and iPhone. Very large files may be slow on older phones.
