FAQs

Which compression mode should I use?

Use Balanced first. If the PDF is still too large, try Small size. Use High quality when image clarity matters more than file size.

Why did my PDF not become much smaller?

Some PDFs are already optimized or contain content that cannot be reduced much without visible quality loss.

Can this reduce scanned PDF size?

Yes, scanned PDFs often compress well because they contain large images, but very high compression may reduce image quality.
