Sık sorulan sorular
How much smaller does the JS get?
Typically 20-50%. Comment-heavy or well-formatted files shrink more; already-minified code shrinks less.
Does it mangle variable names?
No. Only whitespace and comments are removed - variable names are preserved. For name mangling use a real bundler like esbuild or Terser.
Will it break my code?
It preserves the code's tokens. That said, minification via regex has edge cases with regex literals and template strings - for production code, use a proper parser-based tool.
Is my code uploaded?
No. Minification runs entirely in your browser.
