This tool tidies messy HTML with clean indentation so it is easy to read, or minifies it to reduce size for production.
Processing runs in your browser, so your markup is never uploaded.
How to use the HTML Formatter
- Paste your HTML.
- Choose beautify or minify.
- Copy the result.
Untangle minified and messy HTML
Production HTML is often minified into one endless line, and hand-edited HTML drifts into inconsistent indentation that hides structure. The formatter re-indents markup so every element sits at its nesting depth, which instantly reveals structure and makes unclosed tags obvious, since the indentation stops lining up exactly where the problem is.
Reading other people's markup
Formatted HTML is the practical way to study a page saved from the web, review generated markup from a CMS or email builder, or hand off code that others can actually read. Consistent indentation also makes version control diffs meaningful, because changes show up as real edits rather than whitespace noise.
Common uses
- Beautifying minified page source for inspection
- Finding unclosed and misnested tags visually
- Cleaning up markup exported by editors and builders
- Standardising indentation before sharing code
