Why Do PDF Files Become So Large?
PDF files can quickly balloon in size when they contain high-resolution scanned pages, uncompressed bitmap images, embedded fonts, or vector graphics. When sending job applications, legal contracts, or school assignments via email, oversized attachments are frequently rejected by server size caps (typically 25MB).
Key Factors Behind Heavy PDF Files:
1. Uncompressed High-DPI Scans: Standard scanner defaults often capture pages at 300 to 600 DPI in uncompressed color modes. 2. Duplicate Embedded Fonts: Multiple font subsets included for every section. 3. Hidden Background Data: Unseen image layers or metadata added by desktop editing software.Step-by-Step: Compressing PDFs in Seconds
