Every extra space and comment in HTML is a byte the visitor has to download. Minifying trims them and helps pages load faster, especially on slow mobile connections.
How to minify
- Open HTML Minifier and paste your HTML.
- Choose whether to remove comments.
- Copy the smaller HTML.
Always test
Check the minified page in a browser. In rare cases, whitespace matters, for example inside pre tags or between inline elements.
Keep your source
Edit the readable file and minify only the version you publish. Minified code is hard to maintain.
Frequently asked questions
Is my data uploaded?
No. Everything runs in your browser, so what you type never leaves your device.
