Free Online Signature Generator

Yes. It's completely free with no account or sign-up required, and there's no limit on how many signatures you can create or download.

A signature image by itself is just an image — what makes an electronic signature legally binding is the process around it: consent, identity verification, and an audit trail showing who signed and when. For actual contracts, use an e-signature platform like SignFastAi that captures that trail; use this tool for logos, letters, or documents where a simple image is enough.

Yes. The drawing pad supports touch and stylus input on mobile browsers, so you can sign with your finger the same way you would on desktop with a mouse.

Signatures download as PNG files with a transparent background, cropped tightly to your signature so you can drop them into a document without a visible white box around them.

This page just creates a signature image you can save and reuse anywhere. SignFastAi's core product lets you upload an actual document, place signature fields on it, send a secure signing link to someone else, and get back a signed, audit-trailed PDF.
