Create Fillable PDF Form

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.

Create Digital Signature in PDF

A digital signature is a piece of information placed in a PDF document that makes it possible to verify the authenticity of the document. The Pdfcrowd API allows you to programmatically create PDFs containing a digital signature field. Such PDFs can be digitally signed in, for example, Adobe Reader or Preview.

This feature is available starting with Pdfcrowd API client libraries version 5.0.

Quick Start

To add a signature field to a document, set the pdfcrowd-signature class on a DIV element and specify its dimensions.

<div class="pdfcrowd-signature" 
     style="width: 2in; height: 1in; border: 1pt solid black;">
</div>

Our HTML to PDF API will transform this element to a signature field in the resulting PDF.
