Hi Jenn,

The maximum file size for a document to be added in an envelope is 25 MB.  Please view this support article for more information.  

File Size Limitations for an Envelope

This Limit seems incredibly low.  I have a proposal with 1700 pages including many graphics.  I need to add my own signature to the proposal before sending to my customer.  The file size is 96MB.  There is no way to add my signature to this document?  If i separate the page and sign it, it is my understanding that it cannot be recombined with the rest of the document, is that correct?

Hello ​@Jenn G. 
Thank you for reaching out, and welcome to the Docusign Community! We appreciate your question and assure you that we are fully committed to providing you with the best service possible.
The 25MB limit is per document uploaded to an envelope. I suggest that you try to flatten the document: https://support.docusign.com/s/articles/How-to-resolve-a-document-upload-error-by-printing-the-document-to-a-new-PDF?language=en_US. You may also try to split the document and upload it to the same envelope.
