HTML Minifier – Compress HTML Code Online Free
About the HTML Minifier
The HTML Minifier reduces the size of your HTML code by stripping out comments, extra whitespace, and empty lines, without changing how the page renders. Paste your code, choose which optimizations to apply, and get a compressed version instantly, along with a breakdown of exactly how many bytes you saved.
This tool is built for developers and website owners looking to speed up page load times by shrinking HTML file size before deployment. It also includes a basic option to minify inline CSS and JavaScript found within <style> and <script> tags, making it a quick way to clean up code before publishing. If you’re also optimizing your stylesheets, our CSS Minifier can help reduce CSS file size.
During our testing, we verified that the tool removes unnecessary characters while preserving the original HTML structure and page output.
How to Use the HTML Minifier
- Paste your HTML code into the HTML Input box.
- Enable Remove HTML Comments to strip out
<!-- comments -->. - Enable Remove Extra Whitespace to collapse spaces and remove gaps between tags.
- Enable Remove Empty Lines to eliminate blank lines from the code.
- Enable Minify Inline CSS/JS if your HTML contains embedded
<style>or<script>blocks. - Click Minify HTML to generate the compressed result.
- Review the Original Size, Minified Size, and Saved stats.
- Click Copy Code or Download .html to save your minified file.
Example Usage
If you need to optimize JavaScript as well, try our JS Minifier to reduce script size before deployment.
Input:
<div class="example"> <!-- this is a comment --> <p>Hello World</p> </div>
Output (all options enabled):
<div class="example"><p>Hello World</p></div>
In this example, the comment, extra whitespace, and line breaks between tags are all removed, shrinking the file size while keeping the page’s appearance identical.
