Online code highlighting
About Syntax Highlighting
Syntax Highlighting focuses on making code examples easier to read in websites, technical articles, and teaching materials.
Our mission
Make code easier to follow, so readers can focus on what it means.
Code examples are part of how developers explain ideas, document systems, and teach programming.
Our story
The original Syntax Highlighting combined code input, language selection, color themes, preview, and HTML output in one online tool.
Today, you can add line effects, inspect the JSON settings, and export HTML or PNG directly in your browser.
Our principles
Readability
Keep attention on the code and the idea it explains.
A focused tool
Keep code presentation at the center of the product.
Consistent output
Use the same presentation settings for the preview and exported files.
Useful feedback
Use concrete examples to explain issues and requests.
From source code to a finished example
Choose a language and theme, refine the preview, then copy or download your result. If something does not work as expected, send us a reproducible example.
