PDF files are evaluated as they are uploaded to ensure they meet validity and security requirements.

PDFs with the following content will be rejected:

• Does not comply with PDF format standards
• Contains JavaScript
• Encrypted or password-protected
• Contains scripts which can launch an external application
• Contains internal attachments
• Contains audio and video content
• Created with Mac OS X using a fillable form in the Safari browser
• Created with Mac OS X using MS Word and selecting the option, 'Best for printing'

The simplest way to address most PDF upload rejections is to flatten the PDF and then upload it into CM/ECF.
