HTML Beautifier

It reformats messy or minified HTML with clean indentation so the structure is easy to read. It can also minify HTML by stripping unnecessary whitespace.

Formatting only adjusts whitespace and indentation, so in the vast majority of cases the rendered page is unchanged. It reorganises the source, not the content.

Yes. The tool works both ways, so you can expand HTML for readability or compress it to reduce file size. Minifying removes whitespace that browsers do not need.

It uses the bundled js-beautify library running in your browser, so formatting is fast and needs no server. Nothing you paste is uploaded.

No. All formatting and minifying happen client-side in your browser, so your markup never leaves your device. It is safe for private code.

Whitespace-sensitive elements can be affected because beautifying reflows whitespace around tags, which may shift spacing in places like preformatted or inline content. Review such sections after formatting.

It reformats the markup you give it but does not repair structural errors, so malformed tags stay malformed. It is a formatter, not a validator or fixer.
