Code Beautifier
Format and minify HTML, CSS, JavaScript, XML, YAML and SQL in your browser.
How it works
- 1
Paste your code into the input panel.
- 2
Select the language tab and choose Format or Minify.
- 3
Copy or download the result.
What a formatter may touch
- Only whitespace outside tokens: comments, indentation and newlines are re-laid out; string contents are byte-for-byte sacred.
- JavaScript’s automatic-semicolon traps (a return followed by a newline) are guarded so re-indenting cannot change behaviour.
- JSON mode re-indents strictly by depth; JS mode also normalises braces — pick per language instead of running one on the other.
Pretty-printing that never changes meaning
Six languages, one page
HTML, CSS, JavaScript, XML, YAML and SQL share one clean interface.
Instant local processing
Formatting and minification happen immediately in your browser.

Grab the result to the clipboard or save it with the correct extension.
Frequently asked questions
Does it validate syntax?
It reformats the text. It does not guarantee the code is syntactically valid.
Can I format large files?
It works well for typical snippets and medium-sized files. Very large files may lag.
Is my code kept?
No. Everything is processed locally and never uploaded.
