Native Image File Optimization + Resizing is an enhancement of Native Image File Optimization.

 
It allows not only to optimize the images, but also to resize images exceeding a given frame, for instance HD (1920 x 1080 pixels) to make them entering this frame.

With large and very images, this resizing increases a lot the optimization ratios (volume reduction ratios frequently exceeds 90% of the volume of the original image files).

It is interesting to notice that, in the above example where images larger than 1920 x 1080 are resized to match this HD frame, users of HD displays won't see any difference between the original images and the  images optimized by Z-OptimiZr.
In fact, Z-OptimiZr does the same job as the Windows image viewer (reducing the size of the image to HD) but working on the file content instead of working in memory.

Largest images, like 5184 x 3456 pixel wide for instance, are very rarely displayed in their native resolution except for very particular businesses.
Generally users don't even know the real size of images exceeding the surface of their display since they are automatically resized by their viewer before to be displayed.

If this is the case for your users, don't hesitate to use Native Image File Optimization + Resizing to HD instead of Native Image File Optimization alone.

 
The Z-OptimiZr Native Image File Optimization feature does not require Microsoft Office installed on the computer.
This feature has no dependencies towards Microsoft Office.
