Hints on How to Reduce the File Size of a Workbook


How Not to Exceed the 5 MB Maximum Filesize Limit


Due to the nature of the assignment transmission and assessment process, we cannot accept and process workbooks that exceed 5 MB in file size.  If you find yourself with a workbook that exceeds this limit, here are some hints:

  1. Always save as the latest MS Word format.  For example, a file saved as .docx is considerably smaller than one saved as .doc
  2. Images often inflate a submission.  You can reduce the size of images in one of two ways.

a. Take an “image” of your image by using the Windows bundled Snipping Tool accessory.  You can then replace your original image with the snipped image.

b. Double click on an image in your workbook, find the Compress Images icon (indicated below) on the toolbar and follow the instructions in the dialogue box.  Be sure to uncheck “apply only to this picture” if you have more than one image to compress.

3. The best recommendation.  Purchase the NXPowerLite file optimisation program and you can compress any file to the fraction of its original.  PC and Mac versions available from http://www.neuxpower.com This will work as a stand-alone program and will integrate with Outlook, so that you can reduce the size of emails and attachments on the fly.  However, if using this option please don’t send your file as a .zip as we don’t accept .zips due to malware control protocols.

4. Alternatively, there is a free online tool at https://www.wecompress.com/en/ but ISMI isn't able to comment on the security of such online services.

Please don’t send us .pdfs as the assessors need to work inside the workbook, adding comments.
