Top Three Mode of Compressing or Optimizing Images

Lossy Mode:
The lossy optimization option typically saves at least 60% of the initial file weight; with savings of 80% to 90% occurring frequently. Using this option still produces images of outstanding quality, and never of unacceptable quality degradation. In most cases, you will not be able to tell the optimized result from the original, even upon close inspection.

Lossless Mode:
Just as the name implies “Lossless”, this mode will save as much file weight as possible without altering a single pixel, hence the name “lossless” – meaning no information is lost whatsoever. Use this mode when your requirement is that the image should retain 100% of its initial visual information – such as for sensitive brand and marketing visuals.

Expert Mode:
The Expert mode is designed for users who are already familiar with image processing and optimization. Using this mode – by yourself, you can set different quality levels for lossy JPEG and PNG optimization, preserve certain entries in the EXIF metadata, and automatically orient your images.
