HTML Formatter & Beautifier
Format HTML documents with clean indentation and color highlights.
About the HTML Formatter & Beautifier
Format messy HTML with 2 spaces, 3 spaces, 4 spaces, or tabs. Inline elements stay on one line where that is clearly better, and the result is color-highlighted for easy reading. Runs entirely in your browser.
Frequently asked questions
Will it change my markup?
No. The formatter only re-indents; it does not add, remove, or reorder tags.
Does it work with partial HTML fragments?
Yes — fragments without a doctype are formatted using best-practice rules.
