PDF AcroForms

📄 What are PDF AcroForms ?

PDF AcroForms are forms embedded in PDF files that enable users to input data directly within the document. These forms can be completed offline, without an internet connection, and are easily shared and distributed among respondents.

ngSurvey enables you to export your existing surveys and forms into PDF AcroForms with full support for numeric field calculations, validations, skip logic and branching. Once you a PDF has been filled by a respondent you can re-import that PDF and ngSurvey will automatically save it as a respondent for your survey.

If you dont want to show some questions in the PDF AcroForm export you can set the skip logic rules on the question along with the device type set to PDF.
