Frequently asked questions

Which languages can I beautify or minify?
HTML, CSS and JavaScript. Pick the language, paste your code, then choose beautify (readable, indented) or minify (whitespace and comments stripped) depending on what you need.
Will minifying break my code?
No — minification only removes unnecessary whitespace, comments and line breaks; it doesn't change logic or behaviour. The minified output should run identically to the original.
Can I use this to clean up messy or auto-generated code before reading it?
Yes — beautify mode is ideal for that: paste minified or inconsistently formatted code and get a properly indented, readable version back.
Is my code uploaded to a server?
No. Formatting happens entirely in your browser — nothing you paste is sent anywhere or stored. No account is required.
Do I need to install anything or sign up?
No. It runs entirely in your browser — no software install, no account, no email required.
