Why Scanned PDFs Are So Large
Scanned PDFs store every page as a high-resolution image, creating large file sizes.
Documents from scanners, mobile cameras, or photo-based PDFs are typically much larger than text-based PDFs because each page is an image.
iMZi PDF optimizes scanned documents by reducing image quality intelligently while keeping text readable, dramatically reducing file size.
