Adjust page-scale

The Adjust Page Scale feature allows users to adjust the size and scale of pages in PDF documents to optimize document layout and visual effects. Users can choose to maintain the original page size or customize the page size and set the page scale level. This is useful for users who need to optimize PDF document layout or adjust page size. For example, in design documents, users may need to adjust page size to fit different printing sizes; in academic papers, users may need to adjust page scale to optimize chart and table display effects. Additionally, this feature can be used to adjust the size of images or charts in PDF documents for better content display. By adjusting page scale, users can ensure document layout and visual effects and easily manage and distribute them.
