Frequently asked questions

Does it minify inline CSS and JavaScript?

Not aggressively — it only tightens surrounding whitespace. For dedicated inline JS/CSS minification, run those through their own tools before pasting here.

Will IE conditional comments be preserved?

Yes — comments starting with <!--[if are kept intact.

Are my files uploaded to a server?

No. Files are processed directly in your browser using JavaScript and WebAssembly. Nothing is uploaded to our servers, so your documents never leave your device.

Does it work on mobile?

Yes. The tools run in any modern browser on desktop, tablet, or mobile (Chrome, Edge, Safari, Firefox). Very large files may be slower on low-end phones.
