Frequently asked questions

Everything you might be wondering about the HTML Minifier.

What does minifying remove?
Extra whitespace, line breaks, and HTML comments — reducing file size without changing how the page renders.
Is this safe for production use?
Yes for standard HTML. Double-check output if your HTML relies on whitespace being preserved inside <pre> tags or similar edge cases.
Is it free and private?
Yes — free, no sign-up, and everything runs in your browser. Your HTML is never uploaded anywhere.
