FAQ

Can I minify both HTML and CSS here?

Yes. Choose the mode you want, then minify or tidy the code from the same page.

Is this meant for quick cleanup jobs?

Yes. It is a lightweight tool for common snippets and smaller blocks of markup or styles.

Minify markup and styles before shipping them

Whitespace, extra line breaks and repeated formatting make code easier to read during editing but unnecessary in a compact production snippet. A minifier trims that excess quickly.

Useful for embeds, snippets and lighter payloads

This is especially handy when you are sharing code in constrained fields, ad snippets, small widgets or any place where a compact version is easier to manage.

Example

Example: paste a block of HTML or CSS, minify it for production and copy a compact version for deployment or embedding.
