How does compression work computer
Video and audio compression works very differently. Unlike with text where you can have lossless compression, and no data is lost, with images we have what’s called “Lossy Compression” where you do lose some data. And the more you compress, the more data you lose. This is what leads to those horrible-looking … See more To answer that question would involve explaining some very complicated math, certainly more than we can cover in this article, but you don’t need to understand precisely how it works … See more Video works a bit differently from images. You’d think that they would just compress each frame of video using JPEG, and they certainly do that, but there’s a better method for video. We … See more Audio compression works very similarly to text and image compression. Where JPEG removes detail from an image that you won’t see, audio compression does the same for sounds. You … See more WebLossless image compression. Images are all around us, from application icons to animated GIFs to photos. Image files can take up a lot of space, so computers employ a range of algorithms to compress image files. For the simplest of images, computers can use a compression algorithm called run-length encoding (RLE).
