Why this gets reused

Developers often need quick HTML cleanup before shipping snippets, embeds, templates, or static files.

Seeing the reduction instantly makes it easier to decide whether the cleanup is worth keeping.

Browser-based minifying is handy when you just need a fast one-off result without reaching for build tooling.

Having both compact output and a more readable minified mode makes the tool useful in more than one workflow.

Strong first-use cases

Minifying embedded widgets or landing-page sections before publishing.

Cleaning copied HTML from prototypes or internal tools.

Comparing how much whitespace and comment removal trims a template.
