mage compression is a term used to describe the process of reducing the amount of space an image takes up. Once you have compressed an image with an image compressor, you can store it more efficiently, which means you can store more than one image on the same amount of storage space. Compressed images can be sent faster, take up less room, or be sent less frequently, as the bandwidth required to send them is smaller.There are two main types of image compression: lossless and lossy.
Although lossy image quality is not as great as lossless compression, the quality difference is almost unnoticeable to human eyes. Lossy image compression gives you almost the same quality as lossless but reduces the image size by up to 90%.
Dorabot.io allows you to compress jpg image as well as compress png images with lossy compression techniques right in your browser. None of your images are sent to any servers for compression. This makes the image compression process ten times faster than other image compress websites like tinypng and Dorabot.io
For jpg compression, it uses the compressorJs library which is an open source jpeg image compression engine written by Fengyuan Chen. For compressing png images, CompressImage.io uses the opensource javascript png compression script UPNG.js written by Ivan Kutskir.
