Frequently Asked Questions
What is HTML Minifier used for?
HTML Minifier reduces file size by removing unnecessary whitespace, comments, and optional tags from HTML documents. This improves page load times for production websites, reduces bandwidth costs, and helps meet strict file size budgets for performance-critical applications.
How much file size reduction can I expect?
Typical reductions range from 20-30% depending on the HTML content. Documents with lots of whitespace, comments, and verbose formatting see the biggest improvements. Minification is most effective on hand-written HTML rather than output from minifiers.
Will minified HTML still work correctly in browsers?
Yes. Browsers ignore unnecessary whitespace and comments in HTML. The minified output is functionally identical to the original, but browsers parse it faster due to smaller file size. The tool preserves all tags and attributes while only removing non-essential content.
What gets removed during minification?
The tool removes HTML comments (including IE conditional comments), unnecessary whitespace between tags, leading and trailing whitespace, and collapses multiple spaces within text content. Inline JavaScript and CSS remain intact.
Is my data sent to a server?
No. All minification happens in your browser with no server communication. Your HTML, which may contain proprietary code or sensitive content, stays entirely on your device during processing.
What keyboard shortcuts are available?
Press Ctrl+Enter (or Cmd+Enter on Mac) while in the input field to quickly minify your HTML. This enables rapid optimization without switching from your keyboard.
