Will it break my , , or content?

No. Before any cleanup, the minifier stashes the contents of , , , and behind internal markers, runs whitespace and comment removal on the rest of the document, then restores those regions exactly as they were. Preformatted text and inline code keep their original spacing.

Does it remove HTML comments?

Standard HTML comments are stripped to save bytes. The one exception is IE conditional comments that begin with <!--[if, which are preserved because removing them would change behaviour in legacy environments that rely on them.

What exactly does the whitespace collapsing do?

It removes whitespace between adjacent tags (turning > <) and collapses any run of two or more spaces into a single space, then trims the edges. Single spaces inside text content are kept so words do not run together.

What compression stats does it report?

The output panel shows the minified byte size and percentage saved, and a stats line reports the original bytes, minified bytes, total bytes saved, and savings percentage. Byte counts use UTF-8 encoding so they reflect real transfer size.

Does it minify the CSS and JavaScript inside the page?

No. Because the contents of and are preserved verbatim to stay safe, their internal whitespace is not compressed by this tool. To minify those, run the embedded code through the dedicated CSS minifier or JavaScript minifier first, then minify the surrounding HTML.

HTML Minifier

Minify HTML live — strips comments and collapses whitespace while preserving <pre>, <textarea>, <script> and <style> contents verbatim.

About this ToolHow it works, benefits & use cases

Trim HTML down for production while keeping the parts that must stay byte-for-byte intact. This HTML minifier uses a raw-text-aware scanner: it first stashes the contents of <pre>, <textarea>, <script>, and <style> so they are immune to the cleanup, then strips comments (preserving IE conditional comments like ), collapses whitespace between tags, and squeezes runs of multiple spaces down to one. Finally it restores the protected regions exactly as they were, so preformatted text, inline scripts, and styles never lose their spacing. The minified output regenerates live as you type, the output panel shows the new byte size and savings percentage, and a stats line reports original bytes, minified bytes, bytes saved, and the percentage saved. Everything runs in your browser with no upload and no sign-up.

How to Use

1Paste your HTML into the input box, or click Load example to load a sample with comments, a <pre> block, and an inline script.
2The minified HTML regenerates live as you type — the output panel shows the byte count and savings percentage.
3Press Minify HTML to confirm the result and surface any error.
4Check the stats line for original, minified, and saved bytes plus the percentage saved.
5Copy the minified HTML, download it as minified.html, or share the URL with your input encoded in it.

Key Benefits

Raw-text-aware: <pre>, <textarea>, <script>, and <style> contents are preserved verbatim
Strips HTML comments while keeping IE conditional comments intact
Collapses inter-tag whitespace and squeezes multiple spaces to one
Reports original, minified, and saved bytes plus percentage saved
Live minification as you type, with a shareable URL
Byte sizes measured with UTF-8 encoding for real transfer-size accuracy
Runs entirely in-browser — your markup is never uploaded

Common Use Cases

Shrinking a static HTML page or template before deploying it
Minifying email HTML where every byte counts, without breaking <pre> blocks
Removing developer comments and excess whitespace from generated markup
Compressing an HTML fragment or widget for embedding
Measuring how much whitespace and comments inflate a page before shipping
