The Pdfcrowd HTML to PDF API makes it easy to programmatically create fillable PDF forms from standard HTML forms. The API supports most of the HTML form features and, together with support for digital signatures (see Create Digital Signature in PDF), provides an easy way to create PDF forms.
This feature is available starting with Pdfcrowd API client libraries version 5.6.
Simple Example
Add an HTML form field, for example a text input:
<p>Enter name: <input type="text"></p>
Enable generation of fillable PDF forms with the setEnablePdfForms() method:
client.setEnablePdfForms(true)
The resulting PDF will display an interactive input text field.
