About this tool
Paste your HTML and switch between two modes in the browser. Beautify indents nested tags so the document structure is clear and easy to edit, which is perfect for untangling markup copied from a page builder or a minified template. Minify does the reverse, stripping comments, line breaks and needless whitespace to cut the page weight a browser has to download. Copy or download whichever version you need. The markup is processed entirely on your device and never uploaded.
Frequently asked questions
When should I beautify and when should I minify?
Beautify while you are reading, learning from or editing a page, because clear indentation makes the nesting of elements obvious. Minify when you are about to publish, since a smaller file loads faster and saves bandwidth. The two are complementary: keep a tidy, beautified version for development and serve a minified version to visitors of the live site.
Could minifying remove comments or change how my page looks?
Minifying removes HTML comments and trims whitespace between tags, which normally has no visible effect because browsers ignore that spacing anyway. The one thing to watch is whitespace-sensitive content, such as inside a pre or textarea element, where spaces and line breaks are meaningful — keep those in mind, and always minify a copy rather than your only source file.
Is my HTML sent anywhere?
No. The whole process runs in your browser, so the markup you paste is never sent to or stored on a server. That lets you safely format pages that include draft content, internal links or inline data you would not want to share with an online service.
