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 64 color gif.

2

Someone else resized the image to 517 pixels and compressed the image at 42% jpeg quality.

3

Someone reduced to a 34 color gif.

4

Someone else added a bit of contrast, resized the image to 324 pixels and compressed the image at 63% jpeg quality.

5

Then someone resized the image to 461 pixels and compressed the image at 60% jpeg quality.

6

Then they reduced to a 49 color gif.

7

Then they resized the image to 444 pixels and compressed the image at 61% jpeg quality.

8

After that, they resized the image to 549 pixels and compressed the image at 28% jpeg quality.

9

Then they resized the image to 511 pixels and compressed the image at 8% jpeg quality.

10

Someone else resized the image to 568 pixels and compressed the image at 15% jpeg quality.

11

Then they resized the image to 537 pixels and compressed the image at 16% jpeg quality.

13

Someone resized the image to 577 pixels, compressed the image at 20% jpeg quality and someone else added a bit of contrast, resized the image to 352 pixels and compressed the image at 31% jpeg quality.

15

Then someone added a bit of contrast, resized the image to 415 pixels, compressed the image at 9% jpeg quality and then someone added a bit of contrast, resized the image to 457 pixels and compressed the image at 14% jpeg quality.

17

After that and they reduced to a 16 color gif and then someone reduced to a 48 color gif.

19

Someone else added a bit of contrast, added a bit of sharpen because it looked blurry, resized the image to 491 pixels and compressed the image at 12% jpeg quality and then someone reduced to a 47 color gif.

21

Someone resized the image to 305 pixels and compressed the image at 12% jpeg quality and someone else reduced to a 44 color gif.

23

Then they added a bit of sharpen because it looked blurry, resized the image to 302 pixels, compressed the image at 17% jpeg quality and after that and they reduced to a 36 color gif.

25

Someone else added a bit of contrast, resized the image to 349 pixels, compressed the image at 10% jpeg quality and after that, they resized the image to 418 pixels and compressed the image at 24% jpeg quality.

27

Then they resized the image to 391 pixels, compressed the image at 31% jpeg quality and someone resized the image to 328 pixels and compressed the image at 17% jpeg quality.

29

Someone resized the image to 423 pixels and compressed the image at 11% jpeg quality and someone reduced to a 27 color gif.

31

Finally someone resized the image to 399 pixels and compressed the image at 27% jpeg quality.

Oh my, that got pretty bad.
