Qq Space Pictures (Why QQ Space Pictures Blur)

QQ space photo blur should be the server transfer and the underlying code operation. Every time the server is upgraded, the user's files will be transferred. However, the file size transmitted by the server is limited, and the compression speed is accelerated. It is estimated that when upgrading from the first generation to the second generation, the file will be distorted, and the greater the file distortion, the more obvious it will be.

Why are QQ space photos blurred?

After analysis, it is not the pixel problem of the mobile phone, but the picture is compressed when uploading photos in QQ space, which has nothing to do with uploading high-definition original pictures. As time goes by, the photos are slowly compressed. Here are some examples.

Normal image quality upload

We uploaded photos with normal quality. After uploading, the displayed photo size becomes "4 1.2KB". Obviously, the picture is greatly compressed.

High definition image quality upload

We uploaded "HD" quality photos. After uploading, we can see that the size of the photo is still "4 1.2K", which is no different from "normal" image quality uploading. The high-definition quality still greatly compresses the picture.

Original image quality upload

Finally, we uploaded it with the quality of the original picture. The size of the uploaded photo is "7 18.2K", which is very close to the quality of the original image, as shown in the following figure.

Over time, compress the picture.

Over time, the pictures in QQ space will be compressed. For example, a photo I uploaded on June 28th, 20 14 was still very clear at that time. Now, when I open it, I find it is blurred and unclear, and I can't print it at all.

abstract

I dare not save photos in QQ space in the future. After all, many photos carry precious memories. Now, I store the photos in NAS, and then automatically back them up to Baidu's network disk and save them in the original picture.
