Minify HTML online

Paste HTML to strip comments and collapse whitespace between tags, and see exactly how many characters you saved.

Minified output
This is a conservative, rule-based minifier: it removes comments and extra whitespace without renaming variables or rewriting code. It is safe for everyday use, but a full bundler (like Terser or esbuild) shrinks production code further.

Frequently asked questions

Is this as good as a build tool?

No — it is a conservative rule-based minifier. Production sites should use a bundler, but this is handy for quick one-off files.
