Why it matters
HTML from CMS exports, email builders and old sites is often a single unreadable line or a mess of inconsistent indentation. Beautifying it makes it possible to find the bit you need to change.
Minifying HTML saves less than minifying CSS or JavaScript, but on large pages it still trims a few kilobytes. The risk is breaking spacing between inline words or inside pre blocks, which this tool is careful to avoid.

By the numbers
Measured by running this tool's own minifier on leej.uk's index.html at build time: 5% smaller raw, 2% smaller gzipped. The page is already tidy, so the saving is small; pre, textarea, script and style content is never touched.Show the numbers as a table

FAQ
Will minifying change how my page looks?
It shouldn't. Runs of spaces are collapsed to one space, which HTML treats the same, and pre and textarea keep their exact spacing.
Does it fix broken HTML?
No. It keeps your tags as they are. Run broken pages through the W3C validator to find errors.
Does it minify inline CSS and JavaScript?
No, they're kept exactly as written. Use the CSS Minifier for styles.
