To compress, perform the following steps:

  • Load the image to be compressed;

  • Compression can be performed in different quality parameters (from 250 to 0), which can be selected in the settings menu item. The future size of the image depends on the quality parameter. In the settings field, you can immediately see what the output file will be, which allows you to set the desired parameters without wasting time
