Paste HTML to see minified output.
Definition
HTML minification is the process of removing all unnecessary characters from source code without changing its functionality. This includes removing white space, line breaks, comments, and block delimiters, which are useful for human readability but are completely ignored by browsers.
Use Cases
Minification is a critical step in modern web development for deploying production code.
The Mechanics
This tool safely strips out non-essential elements from your code while preserving important formatting inside `<pre>` or `<script>` tags.
Strip CommentsRemoves all standard HTML comments (<!-- -->).
Remove WhitespaceDeletes spaces and tabs between tags.
Remove Line BreaksCondenses the HTML into a single, continuous line for maximum compression.
Capabilities
Paste your code and instantly see the compressed result without page reloads.
Your code is minified locally in your browser. We never send your HTML to a server.
See exactly how many bytes you saved and the percentage of file size reduction.
Instantly copy the minified code to your clipboard ready for production.
Step-by-Step
Paste your raw, uncompressed HTML into the input panel on the left.
The tool will instantly process the code, stripping out all comments and whitespace.
Check the stats panel to see how much smaller the new code is.
Click the 'Copy' button and paste the minified code into your production file (e.g., index.html).
FAQ
Standard minification (removing whitespace and comments) is very safe and will not break valid HTML. However, if your original code relies on CSS `white-space: pre` on generic elements, removing line breaks might alter the visual layout.
