About this HTML Minifier

Lightweight, privacy-first minifier for quick hand-offs and production tweaks. It collapses redundant whitespace, strips regular comments, and leaves critical blocks untouched (script, style, pre, code, textarea), including conditional comments used in legacy HTML. Everything runs in your browser, so your code never leaves your device.

Use the live stats to see byte savings instantly, edit the output in place, copy with one click, or download a ready-to-ship file. For best results, minify the final HTML after your template engine/build has rendered it. Clean markup reduces transfer size and parse time—no CLI needed.

▶ 💬 Frequently Asked Questions

Does it upload my code?
No. Everything runs locally in your browser. Nothing is sent to any server.
