About the HTML Minifier
The HTML Minifier removes comments, redundant whitespace and optional quotes from HTML, showing the size saved. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Cutting page weight before deployment.
- Inlining a template into a script.
- Shrinking an email template under a size limit.
Frequently asked questions
Is the HTML Minifier free, or is there a paid tier?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.
Is the HTML Minifier safe to use with private information?
No. The HTML Minifier runs entirely in your browser using JavaScript. Because the work happens locally, the utility also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What do people use the HTML Minifier for most?
The jobs it is built for: cutting page weight before deployment. Inlining a template into a script. Shrinking an email template under a size limit. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Can I use the HTML Minifier on mobile?
Yes. The page is responsive and the utility works in Chrome, Safari, Firefox, Edge and Samsung Internet on both Android and iOS. There is no app to install and nothing to sign into.
