The maximum file size that can be uploaded is 10MB (per document), with a total maximum size of 20MB for all documents. Although you can upload up to 3 PDF documents, we prefer you combine as many documents as possible into 1 PDF document.
When scanning documents, please scan in black and white to reduce the size of the files. Do not protect the document with a security passcode.
Adobe Acrobat is the recommended application for converting a document into PDF format and combining several PDF documents into 1 PDF document.
