Dedicated JavaScript compression for smaller scripts. Paste code, copy the minified output, and compare input versus output size. A conservative pass that does not rename variables or mangle identifiers.
Lightweight whitespace minifier—not Terser or a bundler. Test after minifying. Use JavaScript Formatter and Minifier for format and minify in one panel.
Paste JavaScript into the input editor. Review the minified output, use Format to beautify, then copy the compact script. Run your tests after minifying—especially if the source relied on automatic semicolon insertion at line breaks.
Example: a 120-byte function with comments and indentation may shrink to ~70 bytes while keeping the same logic: `function greet(name){return 'Hi '+name}`.
Opens the JavaScript Formatter in minify mode. Strips block and line comments and collapses whitespace where safe, producing a smaller script without renaming identifiers.
