BreezyPDF Lite: HTML to PDF generation as a Service

Submit a slug of HTML, get a Google Chrome rendered PDF back.

Build Status Coverage Status


A quick to stand up HTML to PDF service powered by headless Google Chrome. Deploy with one click and start generating PDF's from your web application or command line.

Looking for something more robust?

BreezyPDF Lite was extracted from BreezyPDF as a light weight alternative for new apps. As your software grows, a 1:1 server instance/render ratio will become slow and limiting.

See BreezyPDF.com for Hosted and Enterprise versions which prioritize performance, redundancy, and usability.

Getting Started

1. Submit HTML to be converted

This is done with a POST request the the web server. We'll use some example HTML for this example.

    http://url-of-your-breezy-pdf-lite-server/render/html \
    -d "`curl https://raw.githubusercontent.com/danielwestendorf/breezy-pdf-lite/master/sample.html`" \
    -o example.pdf

This will create the PDF in the current directory by the name of example.pdf.

2. Configure with meta tags (optional)

All configuration for the rendering of your PDF can be configured by meta tags within the HTML you submit. Simply insert the needed meta tag into the head or body of the HTML.

  <meta name="breezy-pdf-width" content="10">
Tag name Default Value Description breezy-pdf-width 8.5 PDF page width in inches breezy-pdf-height 11 PDF page height in inches breezy-pdf-cssPageSize false Use page size defined by CSS breezy-pdf-marginTop 0.4 Top margin breezy-pdf-landscape false Print in landscape mode

View the all the configuration options and their documentation here.

2.a Print Options

There are a number of options for how you want the PDF to be rendered, including height, width, margins, footers, and headers.

2.b Completion Triggers

You might be rendering a Javascript heavy page, so it's helpful to let chrome know when the page is done rendering and ready to be converted to PDF. The default completion trigger is a timer of 5000ms.
