—About HTML Minifier
The HTML Minifier strips comments and excess whitespace from HTML to produce a smaller document that renders identically. It is for front-end developers trimming page weight without adding a build step.
Whitespace and comments add bytes that a browser ignores. Removing them locally lightens the page while keeping your readable source intact, and nothing is uploaded.
Step by step
- Paste the HTML you want to shrink.
- The minifier removes comments and collapses redundant whitespace.
- Review the compact output.
- Copy it or download it for deployment.
What it offers

Where it helps

Tips for best results
- Keep the readable source in version control and minify only the deployed copy.
- Be cautious minifying HTML that relies on significant whitespace, such as inside pre or textarea elements.
- Pair minification with server compression for the largest transfer savings.

This runs entirely in your browser
No file or text you enter here is uploaded. Encoding and decoding happen on your device using native browser APIs — close the tab and nothing remains on a server.
