Worked examples and practical tips
PDF compression can trade image detail for smaller files. Results depend on how the original document was made.
Scanned pages
A scan-heavy PDF often offers more room for size reduction than a text-only PDF.
Keep text legible
Try moderate settings first and inspect small text after compression.
Tip: A PDF already compressed efficiently may not shrink much. Keep the original until you have inspected the result.
