Frequently Asked Questions
How much can I reduce PDF size?
Compression depends on the content. High compression can reduce file size by up to 70-80% for image-heavy PDFs. Text-only PDFs may see modest reductions.
Does compression affect PDF quality?
Higher compression levels may slightly reduce image quality inside the PDF. Choose Low for minimal quality loss, or Medium for a good balance between size and quality.
