Overlay Pages

The overlay process in Revu lets you compare two or more PDFs by converting each document to a different color and stacking them on top of each other as layers in a new PDF. Each layer is transparent and blends with the layers below it. Where the colors are stacked directly over each other, they blend to create a darker color, making it easier to see which elements have changed and which ones have remained the same from revision to revision. There is also a batch version of Overlay.

This feature is similar to Compare Documents, which compares two or more PDFs and uses markups to identify differences. Use the one that most closely matches your desired outcome.

Note: The Overlay function works well for PDFs with vector graphics, while Compare Documents is best suited for working with scanned images or drawings.
