Questions
What is the difference between an electronic and a digital signature?
Sign PDF places an image of your signature on the page. A digital signature uses a certificate to show the file hasn't changed; use Digital signature for that.
Are my files uploaded?
Runs in your browser, so your file is not uploaded.
Is Sign PDF free?
Yes. No signup and no watermark.
Will it work on an old phone?
Yes for most files. On low-memory phones files up to 20 MB are safest; above your device's limit you get a warning and can try anyway.
Does it work on Mac, Windows, iPhone and Android?
Yes. It runs in any current browser, so there is nothing to install on any of them.
