What does HTML minification do?

It removes unnecessary whitespace, comments, and redundant characters from HTML to reduce file size and improve page load speed.

Will minification break my HTML?

For standard HTML, no. However, whitespace-sensitive content (like pre tags) may be affected. Always test after minifying.

Is my code stored anywhere?

No. All processing happens in your browser. Your code never leaves your device.

Does minification break HTML functionality?

No. Minification only removes whitespace and comments that have no effect on how the HTML renders or functions.

Is my code sent to a server?

No. HTML minification runs entirely in your browser using JavaScript string processing. Your HTML source code is never transmitted to any server — it stays within your browser tab throughout the operation.
