Sign a PDF for free
Fill in a form, add your signature, initials and today's date, and save. When the signature has to prove the document hasn't changed, sign with a digital ID instead.

Questions
Is signing a PDF free?
Yes. Fill & Sign and digital signatures are both included in Cloud PDF, which is free.
Can I sign a PDF without printing it?
Yes. Fill in the form on screen, place your signature, and save. Nothing needs to be printed or scanned.
What's the difference between a signature and a digital signature?
Fill & Sign adds a picture of your signature to the page. A digital signature uses a certificate to prove the document hasn't changed since you signed it, and can carry a timestamp of when you signed.
Is it legally binding?
That depends on where you are and what you're signing. Cloud PDF makes PAdES certificate signatures with timestamps and long-term validation; check what your document requires.
Can I sign in my browser?
Yes. Fill & Sign works in Chrome and Edge, and so do digital IDs from a .pfx or .p12 file or one you create in the browser. Smart cards and the Windows certificate store need the desktop app.
