NXPowerLite for File Servers settings

Custom Optimization Settings profiles

Our default Optimization Settings profile is recommended because these offer the best trade-off between reduction performance and quality and should suit most cases.  However, it is possible to create/select different optimization settings profiles if required. To create a new Optimization Settings profile, select the option 'New profile...' in the Optimization Settings drop-down when configuring a folder. See Configuring folders (Adding, removing & setting rules) for more information.

Note: If you subsequently need to edit a custom profile, this is possible by clicking the relevant option in the 'Profiles'  menu item.

Image Optimization

JPEG Quality

This sets the level of quality used by NXPowerLite when recompressing JPEG files. Lower values will result in more disk space reclaimed but will reduce the visual quality of images. We recommended using our default settings because these offer an excellent balance between space saving and quality.

Resize images for display at:

Documents often contain very large images, taken with digital cameras for example, which contain far more visual information than will ever be seen by a user in normal use. NXPowerLite can scale these images down to target a particular display resolution.


Delete private application data

Applications that create PDFs files, such as Adobe Photoshop or Acrobat, are able to store information within a PDF file that they can use when opening or editing the file. This information can only be used by the application which created the file and is not needed to display a PDF file. For most cases, we recommend deleting this data as it will have no effect on the use of the PDF file.

Microsoft PowerPoint, Word & Excel

Delete cropped areas of pictures

Enabling this feature will trim cropped images within documents so that only the visible portion is stored in the file. This will reduce the size of the files, but users will no longer be able to edit cropped images to reveal the areas that have been removed.

Flatten embedded objects

Enabling this feature will cause embedded documents within document files to be "flattened", converting them into pictures. This will reduce the size of the files but users will no longer be able to double-click embedded documents to edit them.

For example, a Word document might contain an embedded Excel sheet with a table of figures. Double-clicking the table would normally open Excel to edit the figures, but flattening the document converts the table to a simple picture, preventing this from happening.

Microsoft PowerPoint Only

Optimize images on slide masters

It is possible to select whether or not images that appear on slide masters will be optimized. If this setting is enabled then all images in the PowerPoint will be optimized. If it is disabled NXPowerLite will not process images that appear on slide masters.


Remove EXIF data

JPEG images normally include extra information (metadata) inside the file such as the device on which the image was taken or location the image was taken plus many more. By default NXPowerLite will retain this data however, this option enables this data to be removed from each JPEG file.

Note: There are currently no settings for PNG or TIFF files

Profile Name

Each profile has to be given a unique name, although you can use the same profile name for another type of profile i.e. Files To Include profile or Schedule profile. We suggest using a descriptive name to help explain what it does or a specific area to which it should be applied. For example, you may want to call a particular profile 'Hidden data not deleted (12 months)' or 'Marketing area'.
