Here, we have an uncompressed image and it uses 46 megabytes of space.
And over here, we have the same image as a compressed JPEG and it uses 4.1 megabytes.
Can you see the difference?
What about when we zoom in so that we can see the individual pixels?
Well, in this video, we're going to take a deep dive into the JPEG algorithm and see how images can be compressed to just a tenth of their uncompressed file size, all while keeping the same image resolution and a very high-quality appearance.
To begin, let's take a quick 26 seconds to understand the importance of this algorithm, why we're making this video, and truthfully, why you should stick around.
First, most digital images from your phone or a camera are saved using the JPEG format.
Second, I spent a couple hours on the Internet recording which images were JPEG versus other formats and found that 86% of the images were JPEGs.
So, essentially, this algorithm is everywhere.
Third, video compression algorithms such as H.264
