Will minifying HTML break inline JavaScript or CSS?

No. Our minification algorithm safely isolates , , and tags, preserving internal whitespace and syntax required for code execution.

Can I restore minified HTML back to readable code?

Yes. You can use our Online HTML Viewer or HTML Editor to beautify and re-indent minified markup.

How much file size reduction can I expect?

Typical HTML documents experience a 15% to 35% reduction in size, depending on the volume of comments and structural formatting in the original code.
