Why Use Electronic Signature Software?
Electronic signature software lets you collect legally valid signatures online without printing, scanning, or mailing documents. This saves time, reduces errors, and makes it easier for people to sign from anywhere.
Many websites require signatures for documents such as:
- Terms of service and consent forms
- Customer approvals for online products or subscriptions
- Petitions and supporter signups for nonprofit organizations
Collecting physical signatures can slow everything down. You may need to print documents, mail them, or wait for scans and photos, especially when people are in different locations.
Electronic signature tools remove that friction by letting users sign directly on your website using their mouse, touchscreen, or keyboard.
Using the right e-signature software also helps you:
- Speed up approvals, onboarding, and sales.
- Store signed documents securely in one place.
- Reduce paperwork and administrative overhead.
- Avoid printing, scanning, faxing, or mailing documents.
If you collect signatures from the public, digital forms can also increase completion rates. For example, publishing a petition or consent form online makes it easier for people to sign instantly, without downloading or returning paperwork.
How We Test and Review WordPress Electronic Signature Software
When reviewing electronic signature software for WordPress, we focused on how each tool performs in real-world scenarios, such as collecting signatures on forms, contracts, and agreements without creating extra steps for users.
Specifically, we tested each plugin or platform using the following criteria:
- Signature collection experience: We tested how easy it is for visitors to add a signature using a mouse, touchscreen, or keyboard, and whether the signing process works smoothly on both desktop and mobile devices.
- Form and document setup: We checked how quickly you can add a signature field to a form or document, including whether templates are available and the amount of manual configuration required.
- Signature storage and access: We reviewed how signatures are saved, whether they are stored as images or documents, and how easily site owners can view, export, or manage signed entries from the WordPress dashboard.
- Workflow flexibility: We evaluated features such as conditional logic, typed signatures, and multi-step forms to assess how well each tool supports different approval or consent workflows.
- Integrations and compatibility: We tested compatibility with common WordPress setups, including WooCommerce, email marketing tools, and payment gateways, to ensure signatures integrate with existing processes.
- Pricing and licensing: We compared what features are included at each pricing tier and whether advanced signature features require higher-cost plans.
Now, here are our expert picks of the best electronic signature software for WordPress.
1. WPForms
WPForms is the easiest way to collect electronic signatures in WordPress, thanks to its simple, form-based solution that works right out of the box. It’s designed for beginners, so you can create signature forms, consent forms, and agreements without complex setup or technical configuration.
At WPBeginner, we use WPForms for our contact forms, annual user surveys, and even forms for free tools like our email signature generator.
For more information, you can check our complete WPForms review.
WPForms includes a large library of ready-made templates, but what stood out during testing is how quickly you can start with forms that already match common e-signature use cases. This includes consent forms, agreement forms, petitions, and approval forms that only need light customization before going live.
Even better, the plugin has a Signature addon that lets you collect digital signatures with ease.
When testing this addon, we found that whenever someone submits a form, WPForms saves their electronic signature as an image and attaches it to their form submission. Then, you can see all of these signatures simply by logging into your WordPress dashboard.
What’s more, you’ll get access to some ready-made templates that already come with a built-in digital signature field upon activating the addon.
This includes an online petition form, a medical and health history form, and even a cattery booking form, which is perfect for running an animal or pet website.
WPForms also has a standalone ‘Signature’ field you can add to any template.
Simply open the WPForms editor and then drag the ready-made ‘Signature’ field onto any form, and you’re ready to start collecting e-signatures.
Once you’ve added the ‘Signature’ field to a form, you can customize it using the WPForms settings.
For example, we marked it as mandatory so that visitors are required to add their digital signature before submitting the form.
With this powerful plugin, you can use conditional logic. This means that you can hide or show the ‘Signature’ field based on the information the visitor enters into the form.
For example, you might hide the ‘Signature’ field unless the visitor opts in to a service requiring their digital signature. In this way, you can show only relevant fields to visitors, which will help reduce form abandonment in WordPress.
It’s worth noting that WPForms is best suited for collecting signatures within online forms, such as agreements, consent forms, and internal approvals. If you need advanced document workflows with identity verification or formal audit trails, then a dedicated document-signing platform may be a better fit.
Why we recommend WPForms: WPForms is hands down the best option if you are a beginner and you want to collect e-signatures using simple online forms. We included it on our list because it has everything you need. It offers a Signature add-on as well as a signature field, which you can trigger using conditional logic.
Pricing: To use the WPForms plugin and Signature addon, you’ll need to buy WPForms Pro ($199.50 per year) or Elite ($299.50 per year). There is also a free version of WPForms that allows you to create simple forms and collect Stripe payments.
2. Formidable Forms
Formidable Forms is an all-in-one WordPress form builder with a drag-and-drop interface that makes it easy to create advanced forms with signatures. It also includes custom calculators, booking forms, and much more.
For detailed information, you can refer to our complete Formidable Forms review.
It has a Signature addon that lets you collect digital signatures. Visitors can sign your forms using their mouse or touchscreen.
Plus, among all the software on this list, Formidable Forms is the only one that allows visitors to type their signature.
We liked this feature as it can make your forms and documents accessible to people who struggle to sign using a mouse or trackpad.
Every time someone signs your form, the plugin saves the signature as an image that you can view inside your WordPress dashboard.
After installing the addon, you can simply drop the ready-made ‘Signature’ field onto any template where you want to collect digital signatures.
Formidable Forms has over 170 templates, so you should have no problems finding one that perfectly suits your needs.
Plus, Formidable Forms comes with a ‘Signature’ category where you’ll find a selection of templates that have the e-sign field built in.
For example, it has an ‘Esthetician Consent’ template where beauticians can collect clients’ information and get their signed consent.
There are also some other Formidable Forms addons that can help you collect and manage digital signatures.
In particular, we found the ‘Visual Views’ addon to be handy as it lets you display user-submitted information on your website.
For example, if you’ve created a petition, then you can use this addon to show the names of all the people who have already signed. In this way, you can encourage more people to support your petition.
To learn more, you can see our guide on how to display WordPress form entries on your site.
Why we recommend Formidable Forms: We love Formidable forms as an e-signature plugin because it’s extremely powerful. Like WPForms, it gives you multiple options for creating forms with e-signatures. You can use the Signature addon or the signature field.
That said, it’s important to keep in mind that Formidable Forms targets advanced users and developers, which means it isn’t as user-friendly as WPForms. The good news is that it’s a powerful and flexible solution that’s also very customizable.
Pricing: To use Formidable Forms with the Signature addon, you’ll need to purchase Formidable Forms Business license ($199.50 per year)
3. pdfFiller
pdfFiller is a complete document management solution that allows you to create, edit, and manage documents and forms online.
During testing, we discovered that we could simply upload any PDF, DOC, DOCX, RTF, PPT, PPTX, JPG, PNG, or TXT file, and pdfFiller would turn it into an interactive document. Anyone can then view, edit, and sign the document online using their desktop or mobile device.
The best thing about pdfFiller is that it follows all of the major security laws and guidelines, including GDPR, HIPAA, and CCPA. So, if your form handles sensitive information, then pdfFiller can be a good option.
However, if you do use pdfFiller, then it’s important to mention the platform in your site’s privacy policy. This helps highlight a legal obligation for businesses that use third-party services.
Why we recommend pdfFiller: Overall, we think pdfFiller’s electronic signature software is very powerful. It’s also legally binding in all 50 states, which makes it ideal for small businesses that need signatures on contracts. pdfFiller also offers advanced features you won’t find in other electronic signature plugins, such as the ability to capture a signature with a webcam.
Pricing: The basic pdfFiller plan starts at $8 per month when purchased annually.
4. USLegalForms
USLegalForms is an online library of over 80,000 national and state-specific legal documents covering a huge range of different industries and use cases. Although it technically doesn’t give you e-signature functionality, it could be the perfect complement.
On their website, you’ll find form templates covering everything from hiring to business agreements, leases, invoices, bills of sale, and much more.
When exploring this website, we liked that all of these legal documents are organized into categories. This helps you search by state, so you should have no problems finding what you’re looking for.
With a strong focus on legally-binding documentation, USLegalForms is a great option for businesses. We also think it would be useful for anyone who wants to start legal proceedings without having to pay a professional to draft documents.
Why we recommend USLegalForms: As mentioned, this platform doesn’t offer an e-signature feature. But it could be just what you are looking for if you need legally binding documents in the United States. If it has the templates you need, you can always use them for in-person business, and then you can use WPForms or Formidable Forms alongside it.
Price: You can buy a USLegalForms subscription for $8 per month (billed annually).
5. Gravity Forms
Gravity Forms is another WordPress plugin that helps you create custom forms with signatures. You can easily arrange the different parts of your form, such as text boxes and buttons, by dragging and dropping them. After making your form, you can put it on a web page or post.
We did a deep dive into this tool’s features, which you can see in our Gravity Forms review.
To let people e-sign their form submissions, you can use the Gravity Forms Signature Add-On feature.
When testing the Signature Add-On, we noticed that it lets users sign their names with their fingers on a touchscreen or a computer mouse. The signatures are then saved as image files (PNGs) and kept on your website’s computer.
To get the Signature Add-On for Gravity Forms, you will need the most expensive plan with all the most advanced features. That means you’ll also get the ability to build conversational forms, surveys, user registration forms, and much more.
Why we recommend Gravity Forms: We appreciate that Gravity Forms is user-friendly and offers a straightforward Signature Add-On. That said, since you need the highest tier plan to get it, we think this tool is best for advanced users who can also benefit from its other, more complex features.
Like Formidable Forms, it’s compatible with WooCommerce, so it’s also a good option if you want to use it with your WordPress eCommerce site.
Pricing: To use the Signature feature in Gravity Forms, you have to buy the ‘Elite License’ for $259 per year.
What Is the Best Electronic Signature Software?
After evaluating various options, we believe that WPForms is the best electronic signature software for WordPress. If you want specific templates for legal matters, we recommend USLegalForms as the best e-signature software.
There are dozens of other electronic signatures on the market, such as DocuSign, HelloSign (aka Dropbox Sign), PandaDoc, and others. But they are all unnecessarily expensive for small businesses, so we haven’t included them on our list.
