What affects compression results?
- Best results: PDFs with lots of redundant metadata or unused embedded objects
- Modest results: Already-optimised PDFs or text-only documents
- Image-heavy PDFs: For maximum compression, consider reducing image resolution before creating the PDF
- Encrypted or password-protected PDFs may not compress correctly
