SurveyJS PDF Generator is a JavaScript UI component that allows you to render SurveyJS surveys and forms as PDF files in a browser. It integrates into any JavaScript application, supporting all popular front-end frameworks, including Angular, React, Vue, and vanilla JS. To create a fillable PDF form, the PDF Generator uses the form's JSON definition (schema), which is automatically generated by SurveyJS's form-building component, Survey Creator. This schema defines various aspects of the form, including its style, content, layout, and behavior. If needed, the generated PDF forms can also be pre-filled with user responses collected through SurveyJS's rendering component, Form Library. SurveyJS has no backend restrictions, meaning you can easily save your JSON forms and responses to your custom backend and pass them to PDF Generator whenever needed to create PDF forms in a browser.
