PDF compression uses sophisticated algorithms to reduce file size by optimizing images, removing redundant data, and compressing text streams. Our tool employs multiple techniques simultaneously for maximum efficiency.
Minimal compression, preserves original quality. Best for professional documents and presentations.
Optimal balance between size and quality. Recommended for most documents and general use.
Maximum size reduction. Ideal for web sharing and email attachments where size matters most.
Use high compression (0.6-0.7) as text remains sharp at all levels
Use balanced compression (0.8) to preserve image quality
Use high quality (0.9) to maintain precision and clarity
