Frequently asked questions

Can I compress a PDF without losing quality?

Yes. The 'High Quality' preset optimizes file structure and metadata while preserving visual quality. For most documents, the difference is imperceptible.

Is this free compression tool really free?

Yes. No hidden costs, no watermarks, no trial. Logged-in users get 50 compressions per day. Without an account, you get 3 per day.

What compression levels are available?

Three levels: High Quality (minimal visual change), Balanced (good size reduction with acceptable quality), and Maximum (smallest file size, may reduce image resolution).

How does the compression work technically?

We optimize embedded images, remove duplicate objects, clean unnecessary metadata, and apply deflate stream compression. The exact techniques depend on the compression level you choose.
