What this tool does not do / Limits

This is a simple comment and whitespace minifier. It is not a full optimiser: it does not rename variables, remove dead code, or guarantee identical behaviour for tricky code, so test minified output before using it.

Frequently asked questions

Will minified code run the same?

For ordinary code it should, but always test it, because this simple tool does not understand every language edge case.

Does it shorten variable names?

No. It only removes comments and unnecessary whitespace; names stay exactly as written.
