Z-OptimiZr JPG Picture File Native Optimization

Each of the programs of the Z-OptimiZr Optimization Suite for SharePoint (Z-OptimiZr Real Time, Z-OptimiZr for SharePoint Databases and Z-OptimiZr Client for SharePoint) includes the native JPG picture file optimization feature.

This Z-OptimiZr for SharePoint JPG file volume reduction feature applies natively to the JPG files (the resulting files remain as native JPG file, but made significantly smaller by Z-OptimiZr for SharePoint).

Since the optimized picture files remain as picture files (an optimized JPG file remains as a JPG file) the Z-OptimiZr for SharePoint picture optimization feature achieves the maximum possible level of transparency in terms of volume reduction for picture files.
There is simply no need for any particular software or add-ons other than the usual picture file viewers to open them.

The example below gives an idea of the power of the Z-OptimiZr native JPG optimization feature. This test was performed with Z-OptimiZr Real Time on files being uploaded to a SharePoint file library but the same results could have been achieved using Z-OptimiZr Client for SharePoint or Z-OptimiZr for SharePoint Databases working on files already stored in some SharePoint file libraries:

The screenshot below displays a SharePoint library containing some JPG files:

JPG picture files not optimized


This second screenshot displays another SharePoint library on which Z-OptimiZr SP RT has been made active and to which we have uploaded the same set of JPG files.

The uploaded files appear in the same order in both screenshots.

Look at the differences on the file sizes:

JPG files optimized


As you can see, the Z-OptimiZr SP RT JPG Optimization feature has been able to reduce the volume of the above files by more than 58%!

The resulting files are still native JPG files that can be opened in any JPG viewer or editor with no need for any decompression utility. The image dimensions (width and height) are the same as the dimensions of the original images. There is no perceptible loss of quality.

These results could still be improved by using the Z-OptimiZr SP RT image policy options (like maximum image size in KB, Maximum image width and height in pixels) that would result in resizing smaller the largest images not complying with the specified Z-OptimiZr SP RT image policies.

For instance, by simply specifying a maximum image dimensions of 1,600 pixels by 1,200 pixels (that is probably wider than any of your SharePoint end-user computer display), here are the numbers we obtained on these same files, (more than 90% volume savings):

JPG files optimized 1600 x 1200


The spreadsheets below, issued from the log files of Z-OptimiZr SP RT, give an idea of the power of the Z-OptimiZr SP RT native JPG optimization feature.

This one is for the optimization without resizing images wider than 1,600 x 1,200 pixels showing a global volume reduction of more than 58%:

JPG picture files optimized - log


And this one is for the optimization including the resizing of images wider than 1,600 x 1,200 pixels showing a global volume reduction of more than 90%:

JPG picture file optimization - 1600 x 1200 - log


Yes, this is not a typo; the Z-OptimiZr SP RT image Optimization feature was able to reduce the volume of the above files by more than 90%: 60 MB converted to 5.5 MB.

(Image-03 did not benefit of this max 1,600 x 1,200 pixel reformatting option because its dimensions were already smaller).

For the typical SharePoint users displaying these resized pictures in the Windows 7 or Windows 8 image viewer, it makes absolutely no difference since the optimized images still exceed the size of their computer display.

We encourage you to check by yourself in your own SharePoint environment using the Z-OptimiZr evaluation Kit.

You can for instance run Z-OptimiZr for SharePoint Databases in test mode on some of your existing SharePoint libraries.

Z-OptimiZr for SharePoint Databases, when launched in test mode, produces detailed log files about the savings it would be able to deliver (on line per file) on the specified target libraries without replacing the files in the libraries. These numbers are real numbers since the file optimization is performed for real in test mode. (The only thing that is not done in test mode is the replacement of the files into the libraries).

This is a very quick and easy way to check which kind of volume reduction ratios Z-OptimiZr would be able to deliver on your own SharePoint file and image libraries. You do not even need to use a test library since the processed files will remain untouched in the target SharePoint libraries.

Setting-up Z-OptimiZr for SharePoint Database on a SharePoint server is instant. (This is a batch program installed by a MSI package; all the Z-OptimiZr files are installed in a same program folder).
Running Z-OptimiZr SP DB in in test mode is only a question of launching the Z-OptimiZr SP DB program providing the name of the target libraries on the command line or in a parameter file.
It will take you only a few minutes to start getting numbers.
