    DocRaptor

    DocRaptor

    Expected Behavior

    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.
