How the Code Minifier Works
Minify or beautify JavaScript, CSS, HTML, SVG, JSON, and XML in one tool. See size savings instantly and copy the result.
Minify Code
Remove whitespace, comments, and unnecessary characters from JavaScript, CSS, HTML, SVG, JSON, and XML. Reduce file size for faster page loads.
Format & Beautify
Reformat minified or messy code into clean, readable structure with proper indentation. Perfect for debugging or reviewing compressed production code.
Multiple Languages
Supports six languages in one tool — JS, CSS, HTML, SVG, JSON, and XML. Switch between them instantly without opening separate tools or installing extensions.
Size Comparison
See the original and minified file size side by side with the percentage saved. Instantly understand how much bandwidth you gain from minification.
Frequently Asked Questions
No. Minification only removes characters that have no effect on execution — whitespace, line breaks, and comments. The logic and output of your code remain identical. It is a safe, reversible optimization.
Yes. Minified files are smaller, which means faster downloads and better performance scores. Most build tools (Webpack, Vite, esbuild) do this automatically, but this tool is useful for one-off files or quick checks.
Yes. Paste minified code and choose the Format option. The tool will reconstruct proper indentation and line breaks, making the code readable again. This is helpful for inspecting third-party scripts.
No. All minification and formatting happens entirely in your browser using JavaScript. Your code never leaves your machine, making it safe for proprietary or sensitive source files.
