Frequently Asked Questions
No - this tool runs entirely in your browser using JavaScript. Nothing you paste is transmitted anywhere.
Yes - this tool only removes whitespace and comments, and carefully protects the content of <pre>, <textarea>, <script>, and <style> tags where whitespace can be meaningful, so it never changes how your page actually renders.
It depends on how much whitespace and how many comments your original HTML has - typically 5-20% smaller for normally-formatted, human-readable HTML.
