00 / HTML Formatter
Clean up messy HTML, instantly.
Paste minified, poorly indented, or AI-generated HTML and get a clean, readable, properly formatted version -- while seeing it rendered live on the page.
Readable code, without leaving the page
As you upload or edit, the code panel keeps a clean, consistently indented view of your HTML in sync with what's rendered. Copy the formatted code directly, or export the finished file.
Frequently asked questions
Does this validate my HTML?
No. This formats and pretty-prints your HTML for readability -- it doesn't check for spec compliance or flag markup errors the way a strict validator or linter would.
Can I copy the formatted HTML?
Yes. Copy it directly from the code panel, or export the whole file once you're done editing.
Will formatting change my content?
No. Only whitespace and indentation are normalized for readability -- the actual markup and content stay the same unless you edit them yourself.
Do I need an account?
No. Formatting and editing are free and don't require an account.
