BlendPDF offers three levels: Low Quality (80-90% reduction, ideal for screen viewing), Medium Quality (60-70% reduction, balanced for most uses), and High Quality (40-50% reduction, maintains near-original quality for printing).
Text quality is never reduced as it uses lossless compression. Image quality depends on the compression level chosen. Low quality compresses images more aggressively, while high quality maintains image clarity.
File size reduction depends on content and compression level. Typical reductions are: Low Quality 80-90%, Medium Quality 60-70%, High Quality 40-50%. Documents with many images see the greatest reduction.
Images are compressed using lossy compression algorithms that reduce file size while maintaining acceptable quality. The compression level determines how aggressively images are compressed. Higher quality levels preserve more image detail.
