Python Syntax Highlighter

About this tool

Paste Python code to get color syntax highlighting you can view full-screen, or copy as ready-to-paste HTML (for a blog post, wiki, or documentation page) alongside the plain, unhighlighted text.

Highlighting runs entirely in your browser using Prism.js — nothing is uploaded.

Frequently asked questions

What does "Copy as HTML" give me?

The highlighted markup (with Prism's token class names) as raw HTML — paste it into a page that includes Prism's CSS to reproduce the same coloring, or adapt the classes to your own site's styles.

Does this check whether my Python is valid?

No — it's a highlighter, not a parser or linter. It colors code based on Python's syntax patterns (keywords, strings, comments) even if the code wouldn't actually run.

Can I use this for other file types accidentally pasted in?

The highlighter is configured specifically for Python syntax, so code in other languages will often highlight incorrectly — use a language-specific tool (like the JS/CSS/HTML/SQL formatters) for those instead.
