Frequently Asked Questions
What languages are supported?
HTML, CSS, JavaScript, XML, ERB (Ruby templates), LESS, and SCSS. Each language has its own formatter that understands the syntax.
What's the difference between beautify and minify?
Beautify adds indentation, line breaks, and spacing for readability. Minify removes all unnecessary whitespace to reduce file size for production.
Can I switch between indent sizes?
Yes. Choose between 2-space, 4-space, or tab indentation when beautifying. The indentation setting applies consistently throughout the output.
Does it preserve my code logic?
Yes. Formatting changes are purely cosmetic. Your code's functionality, variable names, string values, and logic remain unchanged.
Is my code uploaded?
No. All beautification and minification happens locally in your browser. No code is sent to any server.
How do the brace-language and Ruby formatters differ?
C++, Go, Kotlin, PHP and Rust share a string- and comment-aware brace-depth indent (default 2 spaces; C++ keeps # directives at column 0), while Ruby indents on keywords such as def, class, if and do...end. JSON errors report line and column computed from the parser position offset; every other language falls back to basic 2-space indent.
