Frequently asked questions
Is my code uploaded anywhere?
No. Code Beautifier runs entirely in your browser — your code is never sent to a server.
Does it support other languages like Python or JSON?
Currently only HTML, CSS, and JavaScript are supported. If you need to format JSON, try our JSON Formatter tool instead.
Will beautifying change how my code behaves?
No. Only whitespace and indentation are changed — the logic and behavior of your code stay exactly the same.
Is there a size limit on the code I can paste in?
There's no hard limit, but very large files may take a little longer to format since everything runs in your browser.
What happens if I paste invalid or broken code?
The tool does its best to format it anyway. Very malformed code may format oddly, or in rare cases show an error — this is a formatter, not a linter or validator, so it won't catch or fix syntax mistakes.
