Minificatore JavaScript
Minimizza JavaScript in modo conservativo.
Minificatore conservativo: rimuove commenti e spazi superflui; non rinomina le variabili. Per una minificazione completa usa uno strumento di build.
Il tuo input è elaborato localmente nel browser — nulla viene caricato, memorizzato o registrato.
Come funziona
- 1 Paste your JavaScript.
- 2 The minified output appears live.
- 3 Copy or download the .js file.
Casi d'uso comuni
- Quickly shrink a small script.
- Remove comments before sharing.
- Reduce inline script size.
- A fast, dependency-free first pass.
Domande frequenti
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.
