Frequently Asked Questions
What does the HTML minifier do?
It removes HTML comments, collapses multiple spaces into one, removes unnecessary line breaks, and preserves content inside pre, code, and textarea tags.
Does it preserve pre and code tags?
Yes. The minifier preserves the whitespace and formatting inside pre, code, and textarea elements to avoid breaking code examples or formatted text.
Is my HTML uploaded to a server?
No. All processing happens entirely in your browser. Your code never leaves your device.
