Lossy vs. Lossless Compression

This video explains the difference between lossy and lossless compression. Today people go online to watch videos, view photos from loved one, and listen to music. However, nothing is worse than watching or listening to low quality material, yet, sometimes that happens in order to make room for multiple files or save upload time. Lossy compression represents a match of the data but not exactly. Essentially bits of data that are redundant get tossed out to decrease file size. Audio, images, and video are usually lossy compressed to be uploaded to the web faster. The quality is sacrificed and the file can't be restored to it's originally state. Lossless compression is the exact opposite. Lossless compression preserves the data even when it's compressed. Think about when you have to zip your files into a folder in order to share over the web. This is mostly used by spreadsheets and text files. If you lossy compressed these files, they would be useless because information would be omitted. Towards the end, there is a demo of an image in lossless compression converted to lossy compression.

Thank you for clearing this issue up in a very basic way.

the music was a tad bit distracting imo but good vid otherwise

I prefer lossless over lossy, some of my acquaintances who uploads "Phineas and Ferb" and sync it, they use lossless compression on audio and video. Why you asked? Because we understand how important is to retain that original data, I don't use .mp3 no more.

I use .flac, it's like .wav, but smaller. .flac is perfect, because 1, it's lossless, and 2, more managable size, smaller than .wav, but bigger then .mp3.

I like your way of speaking.
You must be really sweet person.
