Frequently Asked Questions

What does HTML minification do?

HTML minification removes unnecessary whitespace, newlines, and HTML comments from your markup. The browser renders the page identically, but the file is smaller, reducing Time to First Byte (TTFB) and improving page speed.

Is it safe to remove HTML comments?

In production, yes. HTML comments are developer notes and conditional IE comments that are invisible to users. Removing them reduces file size without affecting the rendered page. Ensure you are not relying on comments for IE legacy support before removing.

Does collapsing whitespace affect layout?

For most markup it is safe. However, inline elements separated only by whitespace (e.g., two span elements) may lose the single space between them. Review your output carefully if you use inline elements that rely on whitespace separation.

How much size can I save by minifying HTML?

Typically 5–30% depending on how much whitespace and comment content the original file has. Combined with gzip/brotli compression on your server, total savings can be significantly higher.
