The Multi-Page Layout feature allows users to merge multiple pages of a PDF document into a single page for better document content display and printing. Users can select the number of pages per page and whether to add borders to optimize document layout and visual effects. This is useful for users who need to display or print large charts, maps, or design drawings. For example, in design documents, users may need to merge multiple design drawings into a single page for display and printing; in academic papers, users may need to merge multiple charts or tables into a single page for display and printing. Additionally, this feature can be used to create brochures or promotional materials for better document content display and distribution. By using multi-page layout, users can ensure document layout and visual effects and easily manage and distribute them.
