How much can I reduce my PDF size?

Depending on quality setting and content, you can typically reduce file size by 10-50%. Files with many images see the greatest reduction.

Does compression affect PDF quality?

At medium and high settings, the visual difference is minimal. Low quality may show slight artifacts in images but text remains crisp.
