Why Your PDFs Are So Big (And Why That's a Problem)

Ever tried to email a document only to hit a "file too large" error? Or maybe your device storage is groaning under the weight of oversized reports and presentations. Large PDF files are a common headache. They slow down uploads, choke email inboxes, and eat up valuable space on your phone or computer. The culprit is often high-resolution images, embedded fonts, or unoptimized graphics within the PDF.
