Efficiently minify CSS code by removing redundant characters to boost page load performance.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
Paste CSS and choose Minify to create a more compact text version, or Beautify to expand the stylesheet into a more readable layout. The same page supports both directions, making it useful for quick inspection of snippets and small stylesheets.
Minification generally reduces formatting whitespace and comments, while beautification adds indentation and line breaks for easier reading. The result is a text transformation, not a project build: it does not scan your files, update assets, run browser compatibility checks, or confirm that the input is valid CSS.
CSS has syntax where whitespace and comments can matter to how tokens are interpreted. A minifier must handle those cases carefully. This page processes pasted text through a minification library when available and has a simpler fallback path; it does not claim parser-safe handling for every stylesheet or guarantee behavior equivalence.
Use the output as a draft. Compare important selectors and values, then test it in your project and browsers before replacing production CSS. The W3C CSS Syntax specification describes CSS parsing and notes that serialization details for whitespace and comments are not generally defined by that specification.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Work with a copy of your source, especially if it is part of a live project. This tool accepts pasted CSS text rather than rewriting files in a repository.
Choose Minify for a compact result or Beautify for a more readable arrangement. Beautify provides indentation options; the minification mode is a separate operation.
Look for changes around quoted values, URLs, custom properties, comments, and whitespace-sensitive syntax. If the result is empty or an error appears, check the input and try a smaller excerpt.
Compare the source and result, then run your normal checks and inspect the rendered page in the target browsers before using the output in production.
For a short rule such as .card { color: navy; }, beautify helps make the selector and declaration easier to scan; minify aims to remove excess formatting. Treat the output as reformatted text, not as a size report or a guarantee that every declaration remains equivalent.
Use cases
See how the tool fits into real work and everyday tasks.
Beautify a small one-line rule while investigating a selector or declaration copied from another source.
Format a short stylesheet excerpt so teammates can inspect its structure more easily.
Minify a snippet for an experiment, then verify it in the project where it will be used.
Q&A
Find concise answers to common questions and confusing cases.
No guarantee is made for every input. Review output and test it with the project's build and browser checks before replacing a stylesheet.
No. Formatting output is not a syntax validation report, and a returned string does not certify that a browser will interpret it as intended.
No. It processes the text you paste and does not rewrite project files, combine assets, or replace your build pipeline.
Notes
Review scope, result limitations, and important precautions before use.
Keep your original stylesheet until you have reviewed and tested the transformed text. This page does not promise functional equivalence, parser-safe minification, compatibility fixes, project-wide changes, or production readiness. Test with the application and browser versions that matter to your work.
