Frequently asked questions
How can I reduce PDF size for email?
Upload the PDF, choose “Recommended” compression and download the smaller file.
Will compression lower the quality?
Pages are re-encoded as optimized images. Recommended keeps text sharp; extreme gives the smallest file. Text will no longer be selectable.
