JS Minify Tool

What is Minifying JavaScript?

Minifying JavaScript refers to the process of removing all unnecessary characters from the code without changing or affecting the way it works.

The characters that are typically removed include whitespace, comments, and line breaks. You can even shorten parameter names using the JS minifier. It’s a crucial optimization technique to make the code lightweight and faster to run, parse, and get executed by the JS engine.

Minification vs. Compression

While both minification and compression reduce file sizes, they aren’t the same.

Minification, as described, removes unnecessary characters from the code itself without affecting its functionality. This process typically occurs before the file is served to the user.

Compression, on the other hand, involves encoding the entire file using algorithms like GZIP or Brotli to reduce its size. This process is usually handled by the server and browser and occurs during the transfer of the file over the Internet. The compressed file is then decompressed by the browser before execution.
