Frequently asked questions
Does it replace clang-format?
No. clang-format applies a full style configuration across a project; this tidies snippets quickly in the browser.
Is the C++ Formatter free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
Will formatting change how my code behaves?
Formatting only changes whitespace and layout. Minifying removes comments and whitespace and may shorten names, so keep the original source in version control.
