How to use

How to minify CSS for production or beautify it for editing

  1. 1 Paste your stylesheet into the input panel whether it is a full CSS file, a component snippet, or raw copied styles from devtools.
  2. 2 Choose Minify when you want to remove comments and extra whitespace for smaller production-ready output.
  3. 3 Choose Beautify when you need readable indentation before debugging, refactoring selectors, or sharing the code with teammates.
  4. 4 Review the byte counters to compare the original size with the result and quickly see how much output changed.
  5. 5 Copy the transformed CSS and paste it into your project, documentation, or deployment pipeline once the formatting looks right.

CSS often moves between two extremes: dense one-line production assets and hand-edited source files that need clear spacing. A browser-based minifier and beautifier is helpful because it handles both directions in a single page. You can compress copied styles for demos or embeds, then switch to a readable format when you need to audit declarations, compare selectors, or clean up inherited code from another project.

The size panel adds practical context while you work. Minification can reduce bytes by stripping comments, repeated spaces, and unnecessary line breaks, which is useful when you are comparing before-and-after output. Beautifying does the opposite by prioritizing readability, making it easier to spot long selectors, nested rule blocks, and properties that should be grouped or reorganized before shipping a final stylesheet.
