## 👋 Hey! Nice that you are here!
On this website, I show you the rendering results of different html2pdf tools. I compare mPDF, typeset.sh, PDFreactor, wkhtmltopdf, WeasyPrint, Prince, and Puppeteer.
## 🔬 Test Sections
$sSubPages
## 🔬 Test Conditions
For all tests, each tool uses the exact same HTML and CSS input. I do not set any special options the tools might offer, instead I use the most basic call to render a PDF (with external resources).
For the rendering with Prince and PDFreactor, I use free personal licenses. That's why PDFs generated with these tools have a small logo on the top right corner of each page.
The vendor samples might contain tool-specific syntax. This syntax is not understood by the other tools. That's why some of these tests look best for the vendor providing them.
### Code to Render
I use the following code snippets to create the PDF files. If you want to see the code for this website have a look at the [GitHub Repository](https://github.com/CSS-Paged-Media/html2pdf-tool-comparison).
