The best online form builders make it simple and easy to create forms online, for everything from collecting customer feedback to marketing, often using drag and drop functionality without needing to code.

Online forms are extremely versatile and there are many different reasons to use one. If you are a business selling a product or service, you may want to find out what your customers are thinking. Marketers need forms to convert visitors into leads, and students can use them to collect qualitative data for research projects.

Either way, you'll commonly find that forms are an integral part of project management software as well as customer relationship manage (CRM) software, for precisely these reasons.

Online forms used to be ugly, but that's not the case with the best form builders available. They have evolved in both style and functionality, allowing you to be inventive and creative when it comes to achieving your form-related goals.

It's worth remembering that you may not need every feature that comes with a form builder; it's not necessarily something that should break the bank. Ensure that the one you pick provides just enough functionality for you to achieve your goal. 

Here we feature the best online form builders currently available.
