Why are pictures that are reposted often, eventually become worse quality when screenshots take the same image
In: 1
Every time you upload an image, it undergoes compression to save space on the servers. This compression is lossy, as in the quality of the image degrades when compressed
When you take a screenshot, you are taking it of an image that has already had lossy compression. When you upload it again, it undergoes more compression, reducing the quality further
The more you do it, the lower the quality
