Minify JavaScript in your browser. Remove comments and whitespace, keep license comments when needed, then copy or download the smaller code.
This safe minifier removes comments and whitespace. It does not mangle names, run unsafe compression, or execute your code.
Minify valid JavaScript to see the result.
Recent minify results stay in this browser only.
The tool removes unnecessary spaces and line breaks while keeping token boundaries that JavaScript still needs.
Remove all comments for the smallest snippet, or keep license comments when attribution must stay with the code.
Variable and function names stay the same. That keeps the result easier to debug and safer for snippets.
This tool does safe text minification. Use Terser or your bundler when you need AST compression and name mangling.
Some third-party code includes license comments. Use the license option when you are not sure.
Line breaks can matter in JavaScript. Keep the ASI guard on unless you know the snippet is already semicolon-safe.
Readable compact mode is useful when you need smaller code but still want to scan statements.
The saved byte count shows whether minifying a small snippet is worth the reduced readability.
Save a result when you want to compare comment or whitespace settings later in this browser.
