Compress Image

Compression is a big problem when it comes to photographs. You can easily ruin a large image by compressing it too much or too often. If you understand the principles of digital photography compression, you can properly manipulate it to suit the needs of a particular image. Compression is handled by encoders - programs that use a set of algorithms that work with the original image data at different stages of compression. At some of these stages, the original data may be discarded, resulting in lossy compression. When we talk about lossless compression, we mean that there is an algorithm that is the opposite of the compression algorithm, which allows you to accurately restore the original image. There is no reverse algorithm for lossy compression algorithms. There is an algorithm that restores an image that does not necessarily exactly match the original one. Compression and recovery algorithms are selected to achieve a high compression ratio while maintaining the visual quality of the image.

One of the most important inventions in the IT field can definitely be considered a compression format such as JPEG, which is the standard on the Internet today. Thanks to it, we are able to compress images, with virtually no visual loss, tens, hundreds and even thousands of times. Compressing a file is reducing its size while preserving the original data. In this case, the file takes up less space on the device, which also makes it easier to store and transfer over the Internet or in another way. It is important to note that compression is not limitless and usually falls into two main types: lossy and lossless. Images are used on most sites. Visual information is remembered faster than text or audio, and a large percentage of people consider pictures a decisive factor when making a purchase. But heavy images slow down the loading speed of the site, which means that they reduce the actions of users on it. By optimizing images, you can significantly reduce the amount of downloaded data and speed up your site.
