HTML Minifier
Compress HTML by removing comments and extra whitespace between tags — with size savings.
Minify your HTML
The HTML Minifier shrinks your HTML by stripping comments and collapsing the whitespace between tags, without changing how the page renders. Paste your markup and get a smaller version plus the size savings, ready to copy. It runs entirely in your browser, so even large files are processed instantly and privately.
Why minify HTML?
Smaller HTML downloads faster, which improves page load time and Core Web Vitals — factors in both user experience and search ranking. Whitespace and comments that make HTML readable for developers are unnecessary for browsers, so removing them in production trims bytes off every page request with no downside to the rendered result.
What it removes
| Removed | Example |
|---|---|
| Comments | <!-- like this --> |
| Whitespace between tags | > < becomes >< |
| Extra spaces | Multiple spaces collapse to one |
| Leading/trailing space | Trimmed |
How to use it
- Paste your HTML into the box.
- The minified version and savings appear instantly.
- Copy the result for production.
Keep your source readable
Always minify a copy, not your working file. Develop in well-formatted, commented HTML so it stays maintainable, then minify as a build or deploy step. Most build pipelines do this automatically, but this tool is perfect for quick one-off minification of snippets, email templates, or projects without a build process.
A note on whitespace-sensitive content
Be a little careful with content where whitespace is meaningful — for example, inside <pre> blocks or where inline elements rely on a space between them. For typical page markup the minifier is safe; review the output if your layout depends on specific spacing.
Private and free
Your HTML is processed entirely in your browser — nothing is uploaded. The tool is completely free with no limits.
Frequently asked questions
Does minifying change how my page looks?
For typical markup, no. It removes comments and collapses whitespace browsers ignore, so rendering stays the same.
Is it safe for <pre> blocks?
Whitespace inside <pre> and similar elements is meaningful, so review the output if your content relies on exact spacing.
How much smaller will my HTML be?
It depends on formatting and comments, but savings of 10–40% are common.
Is my HTML private?
Yes. Everything runs in your browser and nothing is uploaded.
