Why Are Scanned PDFs Often So Enormously Large?
Office multi-function printers and desktop flatbed scanners frequently save scanned documents at uncompressed 300 to 600 DPI settings with 24-bit full RGB color. A simple 3-page contract scan can easily swell to 15 MB to 30 MB in file weight.
Government recruitment portals (SSC, UPSC), university submission gateways, and corporate email servers routinely enforce strict 1 MB, 500 KB, or even 200 KB upload limits. Attempting to upload an unoptimized file results in immediate rejection.
Choosing the Right Compression Level (Extreme vs Recommended)
Compressing a PDF involves two primary mechanisms: downsampling embedded photographic elements and deflating uncompressed internal text streams:
- Recommended Compression: Re-encodes high-resolution embedded images to 150 DPI while keeping text streams 100% vector-sharp. Reduces file size by 60% to 75% with zero visible degradation on standard computer monitors.
- Extreme Compression: Downsamples images to 72 DPI and aggressively strips non-essential font subroutines. Ideal for passing extreme 100 KB or 200 KB government portal upload barriers.
