| Medium | 40-60% | Slight | Business documents, reports |
| Strong | 60-80% | Noticeable | Text-heavy documents, archives |
Tips to Get Best Results
Maximize compression efficiency while maintaining document quality with these proven strategies:
- Optimize before compression: Remove unnecessary pages, annotations, and metadata
- Choose appropriate levels: Use light compression for final documents, strong for archives
- Test different settings: Compare results to find the optimal balance for your needs
- Consider image content: Documents with many images compress more than text-only files

For PDFs with many images, consider optimizing images separately before creating the PDF. This can result in better compression ratios and quality.
