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 removes characters that have no effect on execution — whitespace, line breaks and comments — and in the aggressive JavaScript mode also shortens local variable names. The logic and output of your code remain identical; formatting can be restored, but comments cannot.
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.
Yes, over HTTPS — minification and formatting run on our server with the same open-source minifiers that build tools use (esbuild, csso, html-minifier-terser). Your code is deleted right after processing and is never stored or logged. Up to 500 KB per request; avoid pasting secrets such as API keys.
