HTML Minifier

How to use

1. 1Paste your HTML into the input area, or click Load sample to try the minifier on a realistic page.
2. 2Toggle the options on the right to enable or disable each transform. The output and the byte savings update in real time as you change settings.
3. 3Watch the live stats: Original, Minified, Saved, and Reduction percentage. They reflect the exact bytes that will be in the copied output.
4. 4Click Copy HTML to copy the minified result to your clipboard, or use Replace with minified to fold the output back into the input for follow-up edits.

About this tool

HTML Minifier compresses HTML source by collapsing runs of whitespace, removing comments, dropping safe attribute quotes, collapsing boolean attributes like disabled="disabled" to disabled, and stripping redundant default type values such as type="text/javascript" on script tags and type="text/css" on style and link tags. The tokenizer treats the bodies of script, style, pre, textarea, code, and noscript as opaque, so embedded JavaScript, CSS, preformatted output, and user-typed form values are never reformatted. Conditional comments like <!--[if lt IE 9]>...<![endif]--> and important comments that start with <!--! are kept by default, so legacy IE fallbacks and license headers survive. Every option is an independent toggle so you can run only the transforms you want, and a live byte counter shows the original size, minified size, bytes saved, and percentage reduction in real time. Useful for trimming production HTML, shrinking server-rendered pages, compressing transactional email templates, preparing snippets for inline injection, and tightening static-site exports before deployment. All work happens locally on your device. Pasted templates, marketing pages, and email content never leave your tab.
