How to Draw on a PDF refers to the process of adding graphical elements, annotations, or sketches to a Portable Document Format (PDF) file. For instance, an architect may need to draw on a PDF blueprint to mark potential renovations.
Drawing on PDFs has significant relevance in fields such as architecture, education, and business. It allows for easy collaboration, feedback, and design iteration. Historically, the ability to annotate PDFs emerged in the early 2000s, significantly enhancing the functionality and versatility of this file format.
