Frequently Asked Questions
What does HTML minification do?+
It removes unnecessary whitespace, comments, and line breaks from HTML code. This reduces file size and improves page load speed without changing how the HTML renders in the browser.
Is my code uploaded to a server?+
No. All minification happens entirely in your browser. Your code never leaves your device.
Will minification break my HTML?+
No. The minifier only removes whitespace and comments. It does not change tag structure, attributes, or content. The minified HTML renders identically to the original.
