Handbrake is an easy-to-use audio and video encoder. This is a great way to make video and music files take up less memory, much less than if you zipped them, and maintains a high quality
The typical use case for this is converting .aiff files to .mp3 files, as Handbrake does not offer this conversion. FFMPEG is a ubiquitous audio/video encoder/converter/streaming software. It actually provides the backend for Handbrake, but this command-line version allows for total control, including a wider variety of files to encode from/to.
WeTransfer is a freemium utility for sharing large files (up to 2GB on the free tier). It allows you to send it directly to an email, or create a link from which anyone can download your file. The premium version pushes the limit per message to 20GB, among other nice features.
Youtube-DL lets you easily download youtube videos from the command line. You can customize essentially every aspect of this process, but to just download a all you need is to enter the URL.
