Frequently Asked Questions

Does this tool minify JavaScript and CSS inside the HTML?

No. This is a basic HTML minifier. It intentionally skips <script> and <style> blocks to prevent breaking inline code.

Is my HTML uploaded to a server?

No. All minification happens instantly on your device. We do not store or transmit your code.

Will this break my website's layout?

In most cases, no. However, if your layout relies on specific HTML whitespace spacing (like inline-block elements), removing spaces between tags might cause slight visual shifts.
