If you wait for a long time to upload an image, then you definitely need to use an image compressor. An image compressor is an application or website that converts the images you want in a way to consume less space. It works by decreasing the image size without affecting the quality of the image. There are a lot of types and techniques to compressor a picture, and you should be aware of them to know which one you’ll need to get the best results out of it.

The lossy data is the best option when compressing images that you want to upload online as the file size is smaller than that of the lossless method.
