HTML Formatter

Paste HTML to validate

HTML Input

Format / Beautify — Pretty-prints HTML with your choice of indentation (2 spaces, 4 spaces, or tab).
Minify — Strips comments and collapses whitespace to produce the most compact HTML string.
Validate — Checks your HTML for structural errors using the browser's built-in parser.
Stats — Shows character count, tag count, line count, and output size.

All processing happens entirely in your browser — no data is ever sent to a server.
