Why do online images appear too grainy and pixelated?

Q. Pictures on my computer/drive are very much okay and in good quality. When I go online, images are pixelated and grainy. Website logos, facebook images, images on my blog, everything are grainy. I am using Sun Cellular broadband. Is it because of the internet connection?

A. Yes you are right that this effect is due to the type of Internet connect. Your cellular broadband provide is compressing the images to improve their network capacity.

The image compression they use is a lossy JPEG compression so the images appear grainy. Their network is optimized for cell phone users with low res screens who won't notice the image quality as much.
