Acroforms (also known as Acrobat forms) is a mechanism to add forms to the PDF file format.

Acroforms permit using objects (text boxes, radiobuttons, etc.) and some code (JavaScript).

Acroforms keep form field values in external files containing key:value pairs. The external files may use different formats, namely ascii, fdf, or xfdf files.

Acroforms were introduced in the pdf 1.2 format[1]. In the pdf 1.5 format, Adobe introduced a new, proprietary format for forms, namely XFA forms. Both formats coexist today.
