PDF Overlay

Combines two or more separate PDF documents into a single file by aligning them precisely on top of each other. Users upload multiple PDFs, specifying which pages from each source need to be merged into one composite document. The tool then stacks these files digitally, creating an overlay effect that allows information from different sources to appear simultaneously within the same viewing area without altering the original content of any uploaded file. Professionals use this capability when they need to stamp standardized forms onto existing documents or compare multiple versions of a layout side-by-side for review. For example, educators might overlay a test template onto student answer sheets, and architects can layer blueprints to visualize structural additions.
