Sign PDF — Currently in the Works
"Signing" means two things. One is laying a signature image onto the document; the other is an electronic signature that proves the document's integrity and the signer with a certificate. The former is just editing that attaches a picture and has nothing to do with legal effect.

This tool isn't available yet
We don't build file pickers for features that can't actually run. Here's the current status and what it would take to ship it.
| Current status | Not available (in preparation) |
|---|---|
| Technology required | PAdES-conformant signing, certificate storage and validation, and integration with a timestamp authority (TSA) |
| Difficulty | Very high |
| Estimated server cost | Certificate and TSA fees dominate rather than server cost, and usually require an annual contract |
| External API needed | Required — a certificate authority and a timestamping service |
What you can do today
If you just need a signature image
Make a page containing your signature image, convert it to PDF, and merge it — that works today with the tools already here.
If you need legal effect
Use a qualified e-signature or contract service. Placing a picture on a document does not create legal effect.
Offering both under the same name could make users misunderstand the effect. An electronic signature needs integration with a certificate authority and a verification system, so we plan to introduce it in stages after clearly separating the two.
