Tokenised, colour-coded HTML you can copy as rich text or export as an image.
Proper tokenisation colours keywords, strings, and identifiers distinctly, which is what makes code skimmable on a slide versus a wall of monochrome text. You can copy it as styled HTML for docs or export a clean PNG for decks, with theme choices tuned for projector contrast.

Syntax highlighting works by tokenizing source code according to language-specific grammar rules, identifying keywords, strings, comments, operators, and other constructs, then applying color and style to each token category. This tool uses a battle-tested highlighting engine that covers languages from JavaScript and Python to Rust, Go, SQL, and more. You can switch themes to match your preferred editor look or your site's color scheme.
All major languages including JavaScript, TypeScript, Python, Java, C, C++, C#, Go, Rust, Ruby, PHP, SQL, HTML, CSS, Bash, and many more.
Yes. Copy the HTML output and paste it into your site. The styles are inline, so no additional CSS is required.
Auto-detection works well for common languages but can misidentify ambiguous snippets. Selecting the language manually guarantees correct highlighting.
