CSS Minifier
Minify CSS by removing comments and whitespace (basic).
About the CSS Minifier
This CSS Minifier removes comments and extra whitespace from stylesheets so browsers download a smaller file. It is a basic compressor for quick paste workflows — useful when you need a compact snippet for a widget, email-safe CSS block, or a small static site without a full frontend build pipeline.
Paste CSS, minify, then copy the result into production. Keep the original formatted stylesheet in version control.
When it helps
- Shrinking critical CSS snippets inlined in
<head> - Preparing a small theme override file for upload
- Checking how much weight comments and spacing add
How to use
- Paste your CSS rules into the tool.
- Run minify and glance through the output for accidental breaks.
- Copy the compact CSS into your live stylesheet or style tag.
Tips
- Advanced calc() / complex nesting may need a dedicated bundler for aggressive optimization.
- Never minify the only copy you have — keep sources readable for debugging.
- After minify, hard-refresh the page to avoid cached old CSS.
FAQ
Is this as strong as cssnano? No. This is a lightweight whitespace/comment pass for simple needs.
Can minified CSS change behavior? Rarely, if a hack relied on specific comment or spacing tricks. Test visual UI after compressing.
