# Signature

The `Signature` field allows you to collect a signature from the user. Feathery allows you to collect legally-binding signatures.

## Signature Methods

You may toggle the available signature methods for users. They can either type, draw, or do both to generate their signature.

## Signature Workflows

You may want to use Feathery's [collaboration workflow feature](/platform/collaborative-workflows/collaboration.md) to invite multiple users to collaborate on a single form, collect multiple signatures in one submission, and restrict each user to filling out specific form sections.

Feathery [Documents](/platform/document-autofill-and-signatures.md) also allow you to collect e-signatures directly on documents with the same signature element.

### For Developers <a href="#example" id="example"></a>

The Feathery SDK and API reference signature fields with `type` equal to `signature`. The submitted value is a `File`.

To trim the whitespace around the signature, it's best to perform server-side processing on your image file.
