About this tool
Paste your JavaScript and the tool removes comments and unnecessary whitespace while keeping strings, template text and regular expressions safe. This is a light minifier: it does not rename variables. For the smallest possible file use a build tool, but this is quick for small scripts and snippets.
When to use it
Remove comments and spaces from JavaScript.
Tips
Use a full build tool for large projects.
Privacy
Everything runs in your browser, so your data is not uploaded or stored.
What it does not do
This simple minifier removes comments and extra whitespace. It does not rename variables or remove dead code, so the saving is smaller than with a full build tool. Always test the minified script.
