When uploading items into the ISN we have a file size limit of 256 Megabytes (256MB) which cannot be increased.
Anything larger will need to be reduced in size.
This would typically be done through the software you obtained your file from, or by way of a web service that specializes in file size reduction (a quick Google search will turn up many free options for this).
You could upload multiple files into a compressed 'zip file' but this is not ideal as the types of documents you'll work with most often are PDFs that need to be sent as PDFs.
If you have any questions about this information please let us know! You can reach us by chat, email at email@example.com, or phone at (800) 700-8112.
