Frequently asked questions
How much smaller will it be?
Typically 40–90% depending on content: image-heavy PDFs shrink the most, text-only documents the least.
Which level should I pick?
The recommended level (5) suits printing and screen reading. Use 7–9 for email where image quality matters less.
Is text quality affected?
No, text stays vector and perfectly crisp. Only images are resampled.
