Python to HTML Converter – Syntax Highlight .py Code (Free, No Upload)

Convert Python code to syntax-highlighted HTML

This converter turns a .py file or pasted Python code into clean, color-highlighted HTML you can put on a website, in a blog post, in documentation, in an email, or in a Word or Google Docs file. It reads your code with a real Python tokenizer, so f-strings, decorators, docstrings, type hints, and match statements are colored the way an editor would color them, not guessed at with a few patterns.

Your code never leaves your browser. There's no upload, so it's safe for private scripts and work projects.

How to use it

1. Paste your Python code, open a .py file, or drop a file onto the tool. Jupyter notebooks (.ipynb) work too.
2. Pick a color theme and font size. The preview updates as you type.
3. Choose an output type (see below), and turn line numbers, wrapping, and the file name bar on or off.
4. List any lines you want to call out in Highlight lines, like 4, 10-12.
5. Copy the HTML, copy the formatted code for a document, download a standalone page, or print it to PDF.

Which HTML output should I use?

Copy formatted puts the highlighted code on your clipboard as rich text. Paste it into Microsoft Word, Google Docs, Outlook, or Gmail and the colors come with it, no HTML editing needed.

What gets highlighted

• Keywords such as def, class, async, await, and yield, plus the soft keywords match and case when they start a statement.
• Strings of every kind: single, double, triple-quoted, raw, bytes, and f-strings. The expressions inside f-string braces are highlighted as code, and escape sequences like \n stand out.
• Docstrings get their own softer style, so documentation reads differently from string data.
• Definitions: function and class names where they're defined, decorators, and function calls.
• Built-ins like print, len, and isinstance, built-in exceptions, self and cls, and dunder names like __init__.
• Numbers in every form Python accepts: 1_000_000, 0xFF, 0b1010, 1.5e-3, and complex numbers like 2j.

Adding highlighted Python to WordPress

Choose "Inline styles," copy the HTML, and paste it into a Custom HTML block in the block editor. Because every color is built in, the code looks the same whatever theme your site uses, and you don't need a syntax highlighting plugin. The line numbers can't be selected, so readers who copy the code get only the code.

Jupyter notebooks

Open an .ipynb file and the tool pulls out every code cell in order, marking each one with an In [n] comment, like jupyter nbconvert --to script does. Markdown cells are kept as comments, so the explanation stays with the code.

Printing and PDF

Print / PDF opens your browser's print dialog with just the code, keeping the theme colors. Choose "Save as PDF" as the printer to create a PDF. For long lines on paper, turn on Wrap long lines first so nothing gets cut off at the page edge.
