What does NXPowerLite do to my files?

Files are often much larger than they need to be. NXPowerLite makes them smaller by removing any excess baggage and converting graphics to the most appropriate file format and resolution. Optimized files remain in their original format, and will be visually and functionally the same as the original. They don't need to be decompressed or rehydrated, and there's no need for special viewing software - so they can be opened and edited by anybody. 

File optimization is "lossy" by design, and below is a list of examples of how it reduces the size of each file type:

PDF (including all sub-sets)
Convert inserted images to the most efficient file format
Adjust the JPEG quality of images
Resize inserted images to the most appropriate size
Remove cropped areas of inserted images
Remove private application data

PowerPoint, Word and Excel
Remove unnecessary metadata
Remove “fast save” information
Convert inserted images to the most efficient file format
Adjust the JPEG quality of images
Resize inserted images to the most appropriate size
Remove cropped areas of inserted images
Flatten embedded documents

JPEG:
Adjust the JPEG quality of images without resizing them

TIFF
Apply lossless LZW compression to TIFF files containing only uncompressed images.
For multi-page TIFF files we will apply lossless LZW compression to uncompressed pages
note

Please note: Any of the above files found in a Zip file can be extracted and replaced with smaller version as described above. Once processed all the files will be re-compressed leaving a file that looks like the original Zip just smaller.
