Personalized course certificate

How it works

1. Bind the personal details

   Encode the learner name and course title before inserting them into HTML.

2. Design the printable document

   Use a bordered layout, clear type hierarchy, an inline SVG mark and explicit page margins.

3. Export through the HTML owner

   Parse the HTML with HtmlConversionDocument and require a successful PDF save.

The example below shows the document API and layout used for this report. Follow the HTML guide for package setup in your own project.

Use this in your project

Replace the course, learner and issue details with your records. Use an actual verification process if the certificate needs to prove completion.
