Meet JS Minify and Beautify, a simple online tool that does exactly what it says: minifies and beautifies JavaScripts quickly and easily. Minify your data without hassles or beautify it into a human-readable format.

Minify (also known as uglify), in computer science is the process of removing all unnecessary characters from source code without changing its functionality. These unnecessary characters usually include white space characters, new line characters, comments, and sometimes block delimiters, which are used to add readability to the code but are not required for it to execute. Minified source code is especially useful for interpreted languages and data interchange formats deployed and transmitted on the internet (such as JavaScript), because it reduces the amount of data that needs to be transferred.

A minified source code may be reversed using a beautify (also known as prettify) process, which applies various stylistic formatting conventions to it. These formatting conventions usually adjust positioning, spacing, and similar modifications intended to make the content easier for people to view, read, and understand.

Easy to use

Begin with the "type (or paste) here..." area to enter your data, then hit the "minify" or "beautify" buttons respectively. After a blink of any eye, the results will be shown below these buttons. Alternatively, use the "click (or tap) here..." area to select JS files from your device, then hit the corresponding button. Once the upload and processing completes, you will be notified to download the resulting minified/beautified JS file. That's all!
