Merge multiple PDFs (2+)

The Merge feature allows users to merge multiple PDF documents into a single PDF document and set the merged document order and whether to remove digital signatures. This is useful for users who need to merge multiple PDF documents into a single document. For example, in academic research, users may need to merge multiple papers or reports into a single PDF document for referencing and distribution; in enterprise document management, users may need to merge multiple manuals, guides, or reports into a single PDF document for employee reading and use. Additionally, this feature can be used to merge multiple contracts or agreements into a single PDF document for better management and auditing. By using the merge feature, users can ensure document content organization and management and easily manage and distribute them.
