What happens when JPEG is saved 600 times

The following video shows what will happen to a JPEG image file when it is saved repeatedly with the compression level increased slightly everytime. When a compression level is increased when you saved a JPG file, the quality decreases as well. So see what happens when it is done 600 times.

Advice for noobs, when you’re editing a JPG file, don’t overwrite the original. Just give your modified file a new name and if you’re editing in a Photoshop for instance, save it under the PSD format.
