Image compression is a digital image processing technology that can reduce unnecessary information in the image through technical means, thereby achieving the purpose of making the image smaller. In fact, there are many ways to make the image smaller. Today, let’s share with you how to compress the image. Let’s take a look at the specific operation methods.
1. Local software such as Fireworks, PS, Meitu Xiuxiu,
Here, take fireworks as an example to teach you how to compress the image to smaller.
Open Fireworks, open the image file, and click the File-Image Preview button in the upper right corner.
Select jpg in the format position and set parameters in the quality position.
Here we can see that there are several M pictures that are compressed only a few hundred KB. Although this can effectively reduce the size of the picture, you can see through the comparison of the picture below that the image quality is greatly affected after the image is compressed. The original clear image and the compressed image can be clearly seen that the image has distortion.
2. Online picture compression tool
Today I will recommend an online compression tool to you. Compared with local software, online tools can be used more conveniently, and the compressed pictures are clearer. Let’s take a look at the specific usage method below.
Open the compressed image website and select the image upload button.
The picture is automatically compressed after uploading. If you are not satisfied with the size of the image compressed, you can adjust the parameters above for secondary compression. The smaller the compression level, the smaller the compressed picture, and the higher the compression level, the clearer the compression level.
After the image compression is completed, click Save the image to save. Let’s compare the difference between the compressed image and the original image.
Here you can see that there is no obvious distortion after the image is reduced, which is consistent with the original image's clarity. Compared with the above image, it is recommended that you choose professional online compression tools when you need to compress pictures in the future, because although local software has more powerful image processing functions, it is a waste of time to download and install, and secondly, it is not a professional image compression tool. Although it can also reduce the size of the image, it has a great impact on the image quality. The above is the method of image compression. Friends in need, come and try it!
