JS Minify & Unminify
Compress or beautify your JavaScript code
How JS Minification & Unminification Works
Minification is the process of removing unnecessary characters (like whitespace, comments, and newlines) and renaming variables to shorter names to reduce the file size of your JavaScript code. We use Terser, an industry-standard minifier, to ensure maximum compression and compatibility.
Unminification (or beautification) does the opposite: it adds indentation and spacing to make compact or "ugly" code readable again. Using js-beautify, we restore the structure of your code so you can debug or analyze it with ease.
Secure & Private Execution
Your source code is your intellectual property. Our tool ensures that your code never leaves your browser.
Unlike many other online minifiers that upload your code to a server for processing, our tool handles everything locally. This eliminates the risk of code leaks, unauthorized storage, or man-in-the-middle attacks. It's the most secure way to process your JavaScript.
