Frequently Asked Questions

How much can I reduce a PDF's file size?

Results vary based on the PDF content. PDFs with large images typically see the biggest reduction — often 50-80% smaller. Text-heavy PDFs with few images may see a smaller reduction.

Will compression reduce the quality?

Light compression preserves nearly all quality. Medium is a good balance. Heavy compression prioritizes size over quality. You can try different levels to find what works best.
