HTML Beautifier

About This Tool

So, you’ve got a block of HTML that looks like it was written by a robot on espresso—no indentation, tags smashed together, and comments buried like treasure. Yeah, we’ve all been there. That’s where an HTML beautifier comes in. It’s not magic, but it’s close. This little tool takes your messy, unreadable code and turns it into something clean, organized, and actually pleasant to look at. No, it won’t fix your broken tags or rewrite your logic. But it will line things up, add proper spacing, and make nested elements actually look nested. Think of it like cleaning up your desk—same stuff, just way easier to work with. I’ve used a dozen of these over the years, and most are either overcomplicated or half-baked. This one? Simple. Fast. Does exactly what it says on the tin.

Key Features

• Formats messy HTML with consistent indentation—2 or 4 spaces, your call.
• Preserves your original content, including comments and inline scripts.
• Handles self-closing tags and void elements correctly (looking at you, and
).
• Works right in your browser—no uploads, no sign-ups, nothing stored.
• Supports large files without crashing (tested up to 500KB, which is more than most people need).
• One-click copy to clipboard—because nobody wants to manually select formatted code.

FAQ

Will this break my code?
Nope. It only adjusts whitespace and line breaks. Your attributes, values, and structure stay exactly the same. If your HTML was invalid before, it’ll still be invalid—just prettier.

Can I use this for minified code?
Absolutely. That’s one of its main uses. Paste in that one-line monster from a CDN or build tool, and it’ll unpack it into something you can actually read. Just don’t expect it to fix missing semicolons or unclosed divs.
