DocRaptor is the best PDF generator for almost every use case
There are several popular free HTML-to-PDF libraries including wkhtmltopdf, PhantomJS, and Chrome Headless / Puppeteer. These tools use the Webkit or Chromium rendering engines, which are designed to display continuously scrolling webpages. In contrast, DocRaptor was built for generating multi-page documents.
This fundamental difference has a tremendous impact on PDF functionality such as page breaks, headers and footers, and variable page sizes. Our conversion engine provides layout and styling options (including CSS Paged Media support) that the open-source PDF engines simply cannot match.
Additionally, as a cloud-based API, we provide professional support, instant scalability, and guaranteed reliability without the costs of long-term maintenance for these libraries and their infrastructure.
There are several enterprise-level conversion software libraries, such as PDFreactor and Prince (DocRaptor uses PrinceXML for PDF generation). These engines create excellent PDF documents.
As an alternative to self-hosting these commercial libraries, DocRaptor offers a much lower price point and provides immediate scalability and reliability. Generating any significant volume of documents typically requires multiple servers, queue management, and other infrastructure—DocRaptor handles all this maintenance and overhead so you don’t have to.
There are also many inexpensive HTML to PDF API services that, at a glance, look very similar to DocRaptor, but they all use open-source, browser-based libraries. As a result, they also suffer from those library’s layout issues and limited functionality. As an official partner of Prince, DocRaptor provides only the highest-quality PDF generation.
