Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To minify HTML, paste your markup into the tool and it strips redundant whitespace and comments in your browser, producing a more compact version. The before-and-after size is shown so you can see exactly how much you saved, then you copy or download the minified output.
Minification runs client-side, so the HTML you paste is never sent to a server. That keeps your markup private and lets you compress snippets instantly without an account, even on staging or proprietary code.
Smaller HTML means fewer bytes over the wire, which can trim page weight and speed up delivery, especially for email templates, embedded snippets, and inline markup. Minifying also makes a snippet easier to drop into a field that has a size limit.
This minifier is a quick, lightweight cleanup step rather than a full build pipeline. It focuses on practical whitespace and comment removal for pasted markup and shows the savings clearly, so it is ideal for one-off snippets rather than production asset bundling.
Short answers for the questions people usually have before trying a utility like this.
Yes. This HTML minifier is free to use with no sign-up and no limit on how much markup you minify.
No. Minification happens entirely in your browser, so the HTML you paste stays private on your device and is never uploaded.
No. It focuses on practical whitespace and comment cleanup for pasted markup, not a complete build pipeline.
Yes. The minified output stays visible so you can review it before you copy or download it.
It depends on how much whitespace and how many comments your markup contains. The tool shows the exact before-and-after size so you can see the savings.
