Is it possible to add a signature to a Google Form?

Not directly. Google Forms doesn’t have a native signature field, but you can work around this by asking respondents to upload an image or PDF of their signature as a file upload, or by using a third-party add-on from the Google Workspace Marketplace to enable basic e-signature functionality.

Collecting signatures in Google Forms (+ a free tool that does it natively)

Q: Are there Google Forms alternatives that offer signature functionality?

Yes. Tools like Typeform, Jotform, Fillout and others support signatures, often as part of paid plans. Weavely is a free alternative to Google Forms that lets you build AI-generated forms and surveys with advanced elements, including a native signature field, without limits on forms or submissions.

Q: What kind of forms might need a signature field?

Many business, education, and service workflows benefit from signature fields, including event registration and consent forms, job applications, medical or health forms, order forms, subscription agreements and approval workflows, where a signed confirmation or authorization is required.

Google Forms is the go-to form builder for many users, thanks to its simplicity and accessibility. But while it’s great for quick surveys or internal feedback, it’s not built for advanced functionality. Many users assume it can handle more complex tasks, like collecting electronic signatures, but that’s not the case.

Google Forms lacks native support for signature fields, along with other key features like design customization and deeper integrations. That’s why, while still popular, it’s often not the best fit for professional or commercial use.

In this article, we’ll show you a workaround to collect signatures through Google Forms. And if you’re looking for a simpler, more reliable solution, we’ll also introduce a dedicated form builder that supports signatures natively, for free.

Adding a signature field in Google Forms

As we already mentioned, Google Forms doesn't natively support signatures. But there are two options how to do it!

Option 1: Use file upload for signatures in Google Forms

Adding a signature field to google forms via file upload

This method asks users to sign elsewhere, save it on their device, and upload it through the form.

Just add a new file upload question. Ask respondents for their signature uploaded as an image or a document. You can customize the settings and restrict the allowed file types to images such as PNG or JPG, or documents like PDFs.

This workaround essentially allows respondents to draw or scan their signature separately and attach it to the form. It is not the most user-friendly option, as it requires more manual work, but it is an acceptable solution if you don't want to use any third-party tools.

Option 2: Use a plugin from the Google Workspace Marketplace

Google marketplace add-on that lets you add a signature to a Google form

If you want to add signature functionality to Google Forms, you can turn to Google's workplace ecosystem. There are several add-ons in the Google marketplace that let you add signatures. For example, like Bolosign. It's a Google Workspace add-on that integrates directly with your Google Forms, allowing you to insert signature fields into your form. Respondents can sign documents electronically, and their submissions will include a legally binding e-signature. To get started, you’ll need to install BoloSign from the Google Marketplace. Once added, you can enable signature capture on a form and customize fields as needed. The add-on offers a free version with basic features but it is very limited in volume. You can only receive up to 5 form submissions and 2 documents on a single form for free.

To get more submissions and access to more features, you'll have to upgrade. Paid plans start at $15/month.
