1. What's the Difference between lossy and lossless image compression?
Lossy compression is a compression technique where some data of the original image is lost during the process. The lost data cannot be recovered, and thus, lossy compression is an irreversible process. Lossy compression works best when you want to reduce the file size significantly and do not mind compromising on the quality a bit which at times cannot be noticed by human eyes.
Lossless compression, on the other hand, is a technique where the images are compressed, and file size is reduced without any quality loss. The image size in this process is reduced by removing the unnecessary metadata from the images. When image quality is important, lossless compression works best.
2. Does compressed JPEG lose quality?
The type of compression method will determine whether the JPEG file will lose the quality or not. If the lossless method of compression is used, the JPEG file will not lose its original quality, while if lossy compression is used, the quality of the JPEG file will be lost. Thus, JPEG quality loss on compression depends on the method and the software used.
Compressing your images using the right tool is very important to ensure that file size is reduced without considerable quality loss, with ease, and with support to added features. Wondershare UniConverter here works as an excellent tool with support to high-quality compression and added features.
