Internet Image Degradation

Do things grow old in cyberspace? The answer is "yes"...

When pictures are constantly copied from website to website, and recompressed and rescaled every time, an interesting loss of quality occurs gradually over time. This page tries to simulate and display this gradual devolution. The first picture is the original.

1

First someone reduced to a 49 color gif.

2

Then someone resized the image to 416 pixels and compressed the image at 60% jpeg quality.

3

Someone reduced to a 60 color gif.

4

Then someone added a bit of contrast, resized the image to 470 pixels and compressed the image at 36% jpeg quality.

5

Someone else reduced to a 30 color gif.

6

Then someone added a bit of contrast, resized the image to 562 pixels and compressed the image at 65% jpeg quality.

7

Then someone resized the image to 315 pixels and compressed the image at 20% jpeg quality.

8

Then they reduced to a 52 color gif.

9

After that and they reduced to a 55 color gif.

10

Then they resized the image to 411 pixels and compressed the image at 34% jpeg quality.

11

After that, they resized the image to 397 pixels and compressed the image at 14% jpeg quality.

13

After that, they resized the image to 339 pixels, compressed the image at 32% jpeg quality and someone resized the image to 302 pixels and compressed the image at 30% jpeg quality.

15

Someone added a bit of contrast, resized the image to 576 pixels, compressed the image at 27% jpeg quality and then someone resized the image to 540 pixels and compressed the image at 14% jpeg quality.

17

Someone resized the image to 522 pixels and compressed the image at 20% jpeg quality and someone reduced to a 41 color gif.

19

Someone reduced to a 11 color gif and someone else resized the image to 554 pixels and compressed the image at 26% jpeg quality.

21

Someone else resized the image to 523 pixels, compressed the image at 33% jpeg quality and after that and they reduced to a 48 color gif.

23

Then they resized the image to 378 pixels, compressed the image at 14% jpeg quality and someone resized the image to 573 pixels and compressed the image at 14% jpeg quality.

25

After that, they resized the image to 422 pixels, compressed the image at 8% jpeg quality and someone else resized the image to 555 pixels and compressed the image at 10% jpeg quality.

27

After that, they resized the image to 477 pixels, compressed the image at 35% jpeg quality and after that, they resized the image to 512 pixels and compressed the image at 30% jpeg quality.

29

Someone reduced to a 46 color gif and someone else reduced to a 31 color gif.

31

Finally someone added a bit of contrast, resized the image to 487 pixels and compressed the image at 15% jpeg quality.

Oh my, that got pretty bad.
