The image you opened should be very large, so it looks very clear, but it will be reduced when uploaded to Alibaba. So you should adjust the pixel when taking the image, so that it will be clear even if it is reduced when uploading. If it is downloaded, it will be unclear.

First, the image pixel is too low. Try to control the pixel of the image uploaded to the Internet to be above 72, otherwise it will be very blurry and unclear.

Second, GIF format images are generally not supported by web pages, and it is best to use JPG format.

Third, the pixel of the screenshot saved is the lowest, so it is no wonder that the effect is not good.
