Frequently Asked Questions

How much can I reduce my PDF file size? +

Compression results vary based on your original PDF content and chosen quality preset. Image-heavy PDFs typically see 50–90% size reduction, while text-only documents may have more modest reductions.

Will compression affect PDF quality? +

Our smart compression algorithms are designed to minimize quality loss. The Screen preset offers maximum compression with some quality trade-off, while Prepress maintains near-original quality with minimal size reduction.
