Every extra kilobyte of HTML slows a page down a little. This minifier strips the parts of your markup that browsers do not need — HTML comments, blank lines and collapsible whitespace between tags — and returns the same page in a smaller file that loads and parses faster.
Careful Where It Counts
Aggressive whitespace removal breaks pages when it touches the wrong places, so this tool plays it safe in the spots that matter. Content inside pre, textarea, script and style blocks is left exactly as written, preserving code samples, formatted text and inline logic. Whitespace that affects layout between inline elements is collapsed following HTML rules rather than deleted blindly. The result is a page that renders the same, at a smaller size — and you see exactly how many bytes and percent you saved before you copy anything.
How to Minify HTML
- Paste your HTML source into the input box.
- Choose whether to remove HTML comments.
- Click minify and review the size savings reported.
- Copy the minified markup, or download it as an .html file.
- Test the page in a browser before publishing, as good practice.
When Minifying HTML Helps
- Speeding up landing pages, templates and email HTML.
- Shrinking static pages before uploading to a host.
- Cleaning exported markup from page builders and CMSs.
- Preparing HTML snippets for embedding in other systems.
Frequently Asked Questions
Will minified HTML still work the same?
Yes, when done carefully — which is how this tool works. Scripts, styles and preformatted text are protected, and the visible page should not change.
How much size can I expect to save?
Comment-heavy, deeply indented source often shrinks by 10 to 30 percent. Already-compact code saves less.
Can I undo minification?
Not exactly — removed comments are gone. Always keep your original, readable source file as the version you edit.
