About this tool
HTML Minifier is a static, client-side tool with no backend. HTML Minifier handles your HTML on your device and shows the result right away.
Generated previews are escaped or sandboxed so pasted markup cannot affect the tool. Nothing you enter is uploaded, and it keeps working offline once the page has loaded.
