What Is PDF Compression?
PDF compression is the process of reducing the file size of a PDF document by optimizing images, fonts, and internal structure. The goal is to make the file smaller without significantly affecting visual quality.
Unlike PDF conversion or merging tools, PDF compression focuses on efficiency and performance, not format changes or document combination.
