Electronic signatures

Add a draw-to-sign pad to a form, store each signature as an image beside the answers, and download the signed submission as a PDF.

The Signature block puts a drawing pad in a form. The respondent signs with a finger, a stylus or a mouse, and the mark is stored as an image with their other answers. It turns a contract, a waiver, a consent form or an offer letter into something that can be signed on a phone without printing anything.

Add a signature field to your form

Open a form in the editor, or create one
Open the insert menu with / and choose Signature

Change the label under the pad if you want: open the block's settings from the handle at its left edge and type into Signature label. It reads "Sign here" until you do. The pad itself says "Draw to sign".

Press Publish. A Required signature block refuses a submit until something has been drawn, with "Please sign" under the pad.

View collected signatures

When the form is submitted, the drawing is saved as a PNG in the same private bucket as a file upload, and the answer holds a reference to it rather than the image itself. In the Submissions tab the cell shows the signature as a small card with Open, Download and Copy link. Only a signed-in member of the workspace can open it; the link a stranger tries answers "not found".

Export signed documents as PDF

Any submission can be downloaded as a PDF from the table, and the signature is drawn on it beside the answers, so a waiver or a contract leaves as one signed sheet.

Open the form's Submissions tab
Hover a row and press Download PDF
The sheet is rendered on the server and downloads

To send a copy without visiting the tab, turn on the PDF attachment on an email notification: the same document then arrives in your inbox, or the respondent's, as soon as the form is submitted. See Turn form submissions into PDF files.

Integrations

A signature travels with the submission everywhere the submission goes. A webhook carries it as a file entry with a name and a link, and the REST API hands it out as a signed link that expires, so a receiving system can fetch the image without holding a session of its own.
