Best practices

For scanned PDFs
Try Aggressive preset with lower image quality (50-70%) and downscale to 150-200 DPI for maximum compression.
FAQ
Do PDFs upload to a server?

What compression preset should I choose?
Balanced works well for most documents. Aggressive is best for scanned PDFs. High quality preserves maximum detail.
How long does compression take?
Processing time depends on PDF size and complexity. Most PDFs compress in seconds, larger files may take a minute.
