For this reason, the JPG format is not suitable for solid-color graphics, screenshots, and icons.
A very large photo can take a while to load depending on the performance of the system and the transfer rate. JPG photos consist of coefficients, or 8 x 8 blocks of pixels, which are normally stored one after the other. This means that the image is loaded one line at a time. In the case of a progressive JPG , the average color value of each coefficient is stored first. In this way, a blurry, pixelated image can be displayed almost immediately.
Color information is then loaded for a quarter and a sixteenth of each coefficient. Gradually, the image quality gets better and better. If you scale an image or apply a color filter or special effect, the image will be recompressed the next time you save it, which degrades quality.
Any lost edge contrasts or colors can no longer be recovered. Compression artifacts are amplified whenever you go back and try to sharpen an image.

JPG format is an excellent choice for digital photos, or high-color screenshots with a picture background, though it performs much worse with detailed images, or images that contain text. The main advantage and, at the same time, the main disadvantage of the GIF is its low color depth.
