FAQ

Is it safe to minify production code here?

Yes. All processing happens locally in your browser. Nothing is transmitted to a server.

Does minifying break my code?

For CSS, no. For JavaScript, simple minification (whitespace removal) is safe. Aggressive variable renaming is not applied here so your code logic is preserved.
