Key features

Reduces file size without changing format

File Optimization carefully targets and removes excess data from files, leaving them smaller but in all other ways identical to the originals. This ensures that file owners will not be aware of any changes to their files.

Effective on already compressed files 

Microsoft Office files are often already compressed and contain lots of pre-compressed content like JPEG images. Unlike standard compression technologies, File Optimization is very effective on these compressed files.

Reduces photos without down-sampling/scaling

It substantially reduces the file size of JPEGs by re-encoding the image using more efficient settings without reducing the image resolution. The image remains visibly unchanged but takes up less disk space.
