Shrink HTML for Faster Pages

Minification removes unnecessary characters — whitespace, comments, optional quotes — without changing how the page renders. Typical savings: 10–40% file size. Every kilobyte counts on mobile.

What Gets Removed

HTML comments (), inter-tag whitespace, consecutive spaces, blank lines, and optionally quotes on attributes that don't need them (id=foo instead of id="foo"). Preserves content inside <pre> and <textarea> tags.

When to Minify

Production deployments, email templates, static site builds, AMP pages. Keep a readable source in git; minify at build time. For development, always work with the un-minified version.

FAQ

Is it lossless?
Yes for visible output. Whitespace-sensitive tags (pre, textarea, script, style) keep their original spacing.

Why Use This HTML Minifier?

The HTML Minifier runs entirely in your browser, which means three things matter for you. First, it's instant — there's no server round-trip, no upload, no waiting on someone else's queue. Second, it's private — nothing you enter ever leaves your device, which makes it safe for sensitive numbers, draft copy, or files you don't want sitting on a third party's servers. Third, it's free forever — no signup, no email capture, no "basic vs. pro" upsell. Open the page, get the answer, close the tab.

Common Use Cases

Cross-checking results from another tool or spreadsheet when accuracy matters
Quick reference during work calls, school assignments, or planning sessions
Sharing the link with a colleague or friend who needs the same answer
Bookmarking for repeat tasks that come up regularly throughout the week

Privacy & How Your Data Is Handled

Every calculation and every transformation in the HTML Minifier runs locally in your browser using standard JavaScript. We don't upload your input to any server, we don't log it, and we don't pass it to a third-party API. The tool works the same whether you're on a fast home connection or completely offline once the page has loaded. If you want to verify this for yourself, open your browser's network tab and run the tool — you won't see any outbound request carrying your data.

Is my data safe?
