Free HTML Minifier Online
An HTML minifier takes a messy document and strips out every byte the browser does not need to render the page.
In most cases, when you write templates by hand, the code is full of indentation and comments so your team can read it. Leaving all that text in the final payload wastes bandwidth for mobile users, so our HTML Minify removes it right before you deploy.
How to Use the HTML Minifier
- Paste your raw markup into the left editor or drop an
.htmlfile on the page. - Check the boxes for the optimizations you want, like stripping comments or collapsing whitespace.
- Watch the right pane update instantly with the compressed output.
- Copy the minified result or save it directly to your drive.
