HTML Formatter & Minifier

Formatted HTML is easier to read, review, and debug. Proper indentation shows nesting structure at a glance, making it faster to spot unclosed tags, misplaced elements, and accidental nesting errors. Teams also benefit from consistent formatting in version-controlled HTML files.

Formatting (beautifying) adds indentation and line breaks to make HTML human-readable. Minifying removes all unnecessary whitespace to produce the smallest possible file — reducing bandwidth and improving page load times. Use formatting for development, minification for production.

This tool strips HTML comments during minification since they add bytes without value in production. If you need to preserve specific comments (e.g., IE conditional comments), add them back manually after minifying.

No. This tool only changes whitespace — it does not alter tag content, attributes, or structure. Pre-formatted blocks like pre and code are handled correctly. Inline elements (like span and a) are not broken across lines to avoid introducing unwanted text spacing.

Yes, for general formatting and review. Note that email clients have strict HTML support requirements — always test formatted email HTML in an email testing tool after reformatting, since some clients are sensitive to whitespace around table elements.
