Code Beautifier & Minifier
Beautify (readable, indented) or minify (smallest size) HTML, CSS, or JavaScript.
A note on JavaScript
Minifying JavaScript safely requires a real parser to avoid breaking code that relies on automatic semicolon insertion or regex literals. This tool does a conservative pass — stripping comments and collapsing whitespace — rather than full identifier renaming, so the output stays correct but isn't as small as a dedicated bundler's minifier.
