Perguntas frequentes
Is my input sent to a server?
No. Everything runs locally in your browser — your input is never uploaded, stored or logged.
How thorough is the minification?
It is deliberately conservative: it removes comments and extra whitespace but does not rename variables or restructure code. For maximum compression, use a full bundler (esbuild, terser).
Could it break my code?
It preserves strings, template literals and regex literals and keeps line breaks to stay ASI-safe. Very unusual code could still differ — always test the output.
Is it really free?
Yes — free, with no signup and no limits.
