Why compress scanned PDF?
Scanned PDFs are notorious for being enormous. When a scanner captures each page as a 300 DPI image, even a 10-page document can balloon to 50MB+. This makes them nearly impossible to email, slow to upload, and wasteful to store. AskPDF's compression is especially effective on scanned documents because there's so much redundant image data to optimize. Expect 50-80% size reduction while keeping the scans perfectly readable.
