Beautify messy HTML with clean indentation, or minify it to shrink page weight — in your browser.
About HTML Formatter, Beautifier & Minifier
Beautify reindents messy or minified HTML into a clean, nested structure that's easy to read, with each element on its own line. Minify strips HTML comments and collapses whitespace to reduce file size for production — while keeping a single space between inline elements so your layout doesn't shift.
Minification is deliberately safe: the contents of <pre>, <textarea>, <script> and <style> are left byte-for-byte untouched, so preformatted text and inline code keep working. Everything runs locally in your browser; your markup is never uploaded.
Minify markup
<section class="card">
<h1>Hello</h1>
</section><section class="card"><h1>Hello</h1></section>
Beautify expands it back into indented, readable HTML.
Frequently asked questions
Is minifying my HTML safe?
Yes. It strips comments and collapses whitespace but preserves a single space between inline elements, and never alters the contents of pre, textarea, script or style — so rendering stays the same.
Can it reformat minified HTML?
Yes. Beautify expands single-line or minified HTML into a properly indented, one-element-per-line layout.
Does it keep my inline CSS and JavaScript?
Yes. The contents of <style> and <script> blocks are preserved exactly. Use the dedicated CSS and JavaScript tools if you want to format those too.
Is my HTML uploaded anywhere?
No. All processing runs locally in your browser.
