Frequently Asked Questions
What does HTML minification do?
Minification removes unnecessary characters like whitespace, comments, and optional quotes without changing how the HTML renders in the browser.
Is minified HTML harder to read?
Yes. Minified HTML is optimized for file size, not readability. Use the HTML Formatter to beautify minified code when you need to edit it.
Can minification break my HTML?
Proper minification preserves functionality. However, whitespace-sensitive content (like inside <pre> tags) is handled carefully.
How much size reduction can I expect?
Typical savings are 20-40% for well-formatted HTML with comments and indentation. Larger files with more whitespace see bigger gains.
