Published September 14, 2026 · 2 min read

Frequently asked questions
No — content inside script, style, pre and textarea tags is protected and left untouched, since whitespace inside those often changes behavior or appearance.
Yes, except for conditional comments (used for old Internet Explorer targeting), which are preserved since removing them could change page behavior in those specific cases.
Conceptually yes — the HTML Formatter adds readable whitespace back in; this tool strips it out for production file size.
Because the minifier is careful about script and style content, you get real size savings without the risk of subtly breaking your page's behavior.
