Supported inputs

  • HTML, CSS, or JavaScript source text, selected with the source-type control.

Frequently asked questions

Will minification preserve behavior?

It is intended to remove comments and redundant whitespace, but it is not a full parser. Verify output with your application tests.

Does it minify all three source types?

Yes. Choose HTML, CSS, or JavaScript before running the minifier.
