Does PDF compression reduce quality?

It depends on the level you choose. Low compression preserves near-original quality, Medium balances size and quality, and High compresses aggressively for the smallest file size.

Is PDF compression free?

Yes, compressing PDFs is free for files up to 10MB. Pro users can compress files up to 100MB.

What is the difference between Low, Medium, and High compression?

Low compression gives a smaller file with minimal quality change. Medium offers a good balance. High compression produces the smallest file but may reduce image sharpness in documents with many photos.

Are my files private when compressing?

Yes. Compression happens entirely in your browser — your files are never uploaded to any server.
