Python Formatter

Normalize Python indentation, strip trailing spaces and clean up blank lines so your code matches PEP 8 style.

Frequently asked questions

What does the Python formatter fix?

It rewrites indentation to a consistent size (tabs become 4 spaces), removes trailing whitespace and collapses excess blank lines.

Will it break my code?

It only adjusts whitespace, not logic. Because Python relies on indentation, review the diff after big files.

Is it free?

Yes. Free, unlimited, no sign-up, fully in-browser.
