CSS Minifier & Beautifier — free online
You finish a stylesheet and it works, but it's full of extra spaces, comments and line breaks that just make the file bigger and the page slower to load. Or the opposite: someone hands you CSS squashed into one long line and you can't read a thing. We added a free tool that handles both ways — CSS Minifier & Beautifier — right in your browser.
What it does
Paste your CSS and pick a direction. Minify strips out the comments, collapses the whitespace and tightens up the punctuation so the file comes out as small as it can be. Beautify does the reverse: it spaces everything out neatly so you can actually read and edit it again.
Nothing leaves your device
It all runs inside your browser. Your CSS is never uploaded to a server and nothing is saved anywhere. When you close the tab, it's gone.
How to use it
- Open CSS Minifier & Beautifier and paste your CSS into the box.
- Choose minify to make it smaller or beautify to make it readable.
- Copy the result and drop it into your project.
It's free with no limit. There are more small tools on the Apps page.
