The Auto Split PDF feature allows users to automatically split large PDF documents into multiple independent documents by inserting separator pages or uploading PDF documents containing separator pages. This is useful for users who need to batch process or archive large numbers of documents. For example, in scanned documents, users may need to merge multiple documents into a large PDF file and then automatically split them into multiple independent documents by inserting separator pages; in contract management, users may need to merge multiple contracts into a large PDF file and then automatically split them into multiple independent contract documents. Additionally, this feature can be used to split large reports or books into multiple chapters or sections for better organization and management. By auto-splitting PDFs, users can ensure document organization and management convenience and easily manage and distribute them.
