With the popularity of smart phones and the development of cameras, taking photos and videos has become a part of most people's lives. High-definition pictures also bring an unusual experience.

This step is relatively simple, just click on the picture to select. Let's start to explain the image compression function

In order to meet the needs of different groups of people for batch image compression, Jiulei Image Converter has designed two modes: basic settings and advanced settings. The basic settings are simple to operate, with a limited range of compression to choose from. Advanced settings have more detailed parameter settings, which are difficult to master, but more flexible.

Image Compression Basic Settings

Compression options : minified compression, normal compression, clear compression

Minification Compression Compressed files are the smallest and have the lowest resolution. Clear Compression The compressed file size is the largest and the definition is the highest.

Output format : format unchanged, JPG format

Because some formats do not have compression available, an option to convert to jpg format is provided here as a supplement to image compression.

Image Compression Advanced Settings

There are several image compression options in the advanced settings, let me explain them one by one.

Compression intensity : The greater the intensity, the smaller the compressed image file, if you don't know how to set the following compression parameters.

Resolution : Resolution refers to the size of the compressed image. If your image does not need such a large size, reducing it is the best solution

Aspect ratio : The aspect ratio is set together with the resolution. For example, if you only input the width, then the height can be determined according to the aspect ratio of the picture.

Cropping/Scaling : Here is how to achieve this resolution after setting the selected resolution. Cropping removes excess footage. Scaling is preserved, but the compressed image is distorted as a result.

Convert and view results

Click "Start Processing" in the lower right corner, and after waiting for a while, you will be prompted that the processing is complete.

After the batch image compression is completed, the status will show whether the compression is successful or failed.

You can locate the compressed image file by operating the small folder icon there .

At the same time, the compression rate of the picture will also be displayed, which is convenient for you to intuitively understand the result of picture compression.
