How does Docpressor preserve quality during compression?

It analyses the file and applies the minimum DPI reduction needed to reach your target. Text and vectors are never compressed.

What MB target gives the best quality-to-size balance?

At 10MB+, quality is virtually indistinguishable from the original. At 5MB, very slight reduction. At 2MB and below, noticeable but acceptable quality reduction.

Are fonts affected by compression?

Never — fonts remain embedded and perfectly sharp at all compression levels.

What about vector graphics in the PDF?

Vector elements (charts, diagrams) are preserved exactly — only raster images (photos, scans) may be compressed.

Compress PDF Preserve Quality — Everything You Need to Know

Quality preservation during PDF compression is about applying the minimum compression necessary, not the maximum. Docpressor's algorithm works backwards from your target size — finding the optimal DPI that achieves the size reduction with minimum visual impact.

For text-based documents, quality is essentially zero-loss at any compression level. Fonts and vector elements are never modified. For image-heavy documents, the quality depends on your target size — higher targets mean better quality.

Docpressor shows you the original and compressed file size before you download, so you can always choose to set a higher target if the compression appears too aggressive for your needs.
