HTML / JS / CSS Minifier
Strip whitespace and comments from HTML, JavaScript and CSS to shrink your production files.
About the HTML / JS / CSS Minifier
HTML / JS / CSS Minifier removes comments, whitespace and redundant syntax to produce the smallest production build of your front-end code. Every kilobyte trimmed shaves milliseconds off your load time.
How to use
- Pick the language (HTML, CSS, JS).
- Paste your source code into the input area.
- Click Minify and copy the production output.
Benefits & key features
- Typical savings: 30-60% on file size.
- Produces output that's still syntactically valid.
- Useful pre-deployment for hosts without a build step.
- Pairs with Code Beautifier if you receive minified code and need to read it.
Pro tip
Always keep the unminified source in version control — minified code is painful to debug. Treat minified output as a build artefact.
