 ! Title: ➗ Actually Legitimate URL Shortener Tool
-! Version: 11July2023v1

 ! Description: In a world dominated by bit.ly, adf.ly, and several thousand other malware cover-up tools, this list reduces the length of URLs in a much more legitimate and transparent manner. Essentially, it automatically removes unnecessary $/& values from the URLs, making them easier to copy from the URL bar and pasting elsewhere as links. Enjoy.
