Product updates, tips & tricks

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.

Postman, a versatile platform for API management, serves as an excellent tool for interacting with the Pdfcrowd Conversion API. This guide provides a comprehensive tutorial on how to use Postman to convert between PDF, HTML, and various image formats using the Pdfcrowd API. Whether you're a developer familiar with Postman or someone exploring API functionalities for document conversion, this guide will walk you through the process step-by-step.
