Is lossless PDF compression possible?

True lossless compression removes only redundant data. At moderate targets (10MB+), quality loss is virtually imperceptible. At 1-3MB, some image reduction occurs.

How does Docpressor preserve quality?

It analyses each page independently, applying minimum compression to hit your target. Text layers are never modified — only image DPI is reduced.

What is the best MB target for quality preservation?

The higher your target, the better the quality. At 10MB+, most users cannot detect any quality difference.

Does compression affect embedded fonts?

No — embedded fonts are completely preserved. Only raster images (photos, scans) are affected.

Not all compression is equal. Docpressor uses intelligent algorithms to reduce file size as much as possible while preserving maximum image and text quality.

Compress PDF Without Losing Quality — Everything You Need to Know

PDF quality loss during compression comes almost entirely from reducing image resolution (DPI). Text, vector graphics, and embedded fonts are not affected by standard compression at all.

Docpressor's intelligent compression analyses each page individually and applies the minimum DPI reduction necessary to hit your target size. At moderate targets (10MB or above), the visual difference between original and compressed versions is imperceptible to the human eye.

For documents where quality is critical — professional presentations, architectural drawings, printed brochures — set a higher MB target to achieve a good balance between size reduction and visual quality.
