If you find that optimizing, compressing, or reducing the file size of a PDF still results in a document too large for submission, some courts allow you to split up your into 2 or more PDFs. However, you will want to reach out to your specific court’s filing clerk first to advise on if splitting a document is allowed for their court.
If you choose to split your PDF up, you will want to make sure you give each one its own separate caption page.
