Does minification change code behavior?

When done correctly, behavior does not change. This tool removes comments and collapses whitespace. It does not rename variables or obfuscate code.

Are CSS calc() and var() handled correctly?

Yes. The CSS minifier safely compresses whitespace within property values.

Can I change the indent size for beautify?

Yes. Use the indent option to choose between 2 spaces, 4 spaces, or tab.
