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 added a bit of sharpen because it looked blurry, resized the image to 456 pixels and compressed the image at 32% jpeg quality.

2

Someone else added a bit of contrast, resized the image to 513 pixels and compressed the image at 59% jpeg quality.

3

After that and they reduced to a 49 color gif.

4

Someone else added a bit of contrast, resized the image to 303 pixels and compressed the image at 23% jpeg quality.

5

After that and they reduced to a 45 color gif.

6

Then someone reduced to a 43 color gif.

7

After that and they reduced to a 29 color gif.

8

After that and they reduced to a 48 color gif.

9

Someone reduced to a 45 color gif.

10

Someone else reduced to a 28 color gif.

11

Someone resized the image to 312 pixels and compressed the image at 25% jpeg quality.

13

Someone added a bit of sharpen because it looked blurry, resized the image to 465 pixels and compressed the image at 8% jpeg quality and someone reduced to a 45 color gif.

15

Someone else reduced to a 42 color gif and then someone resized the image to 348 pixels and compressed the image at 12% jpeg quality.

17

After that, they resized the image to 405 pixels, compressed the image at 22% jpeg quality and then they added a bit of contrast, resized the image to 492 pixels and compressed the image at 14% jpeg quality.

19

Then they resized the image to 469 pixels and compressed the image at 8% jpeg quality and then someone reduced to a 27 color gif.

21

After that, they resized the image to 504 pixels, compressed the image at 20% jpeg quality and someone added a bit of sharpen because it looked blurry, resized the image to 417 pixels and compressed the image at 20% jpeg quality.

23

Someone added a bit of contrast, resized the image to 466 pixels, compressed the image at 14% jpeg quality and then they resized the image to 301 pixels and compressed the image at 8% jpeg quality.

25

Someone resized the image to 339 pixels, compressed the image at 25% jpeg quality and then they resized the image to 536 pixels and compressed the image at 9% jpeg quality.

27

Then someone resized the image to 422 pixels, compressed the image at 8% jpeg quality and after that, they resized the image to 438 pixels and compressed the image at 22% jpeg quality.

29

After that and they reduced to a 42 color gif and then someone reduced to a 28 color gif.

31

Finally someone added a bit of contrast, resized the image to 462 pixels and compressed the image at 14% jpeg quality.

Oh my, that got pretty bad.
