Signature
A digital signature capture field. Respondents draw their signature using a mouse (desktop) or finger/stylus (mobile). The signature is saved as an image.
Configuration
| Field | Description |
|---|---|
| Question text | The label (e.g., "Your signature") |
| Required | Must sign before submitting |
How it works
- The field shows a blank drawing area
- Respondent draws their signature with mouse or touch
- A Clear button lets them retry
- The signature is captured as a PNG image on submission
Common uses
- Contract agreements
- Consent forms
- Delivery confirmation
- Legal documents
- Approval forms
Combine with a Terms & Conditions field: show the terms first, then capture the signature as acceptance.
Digital signatures captured in TinyForms are image-based. For legally binding electronic signatures with audit trails, consider a dedicated e-signature service (DocuSign, HelloSign) connected via a workflow.
Configuration tabs
Every field has 5 configuration tabs when clicked on the form canvas:
| Tab | What you configure |
|---|---|
| Design | Question text, description, placeholder, help text |
| Data | Default value, variable name, prefill from URL parameters |
| Settings | Required/optional, read-only, hidden |
| Validations | Format rules, min/max, custom error messages |
| Image | Attach an image alongside the question |
Using in workflows
When this field is part of a form connected to a workflow via the Form Submission trigger, its value is available as a variable:
{{trigger.fieldName}}
Use it in any downstream node: send it in an email, store it in a database, pass it to an AI node for analysis, or use it in an If-Else condition for routing.
