Will compressing my PDF reduce text and image quality?

PDF compression optimizes images and resources inside the file. You can choose different compression levels to balance file size reduction with visual quality.

Are my sensitive documents safe during PDF compression?

Yes. Since all PDF compression takes place locally in your browser, your sensitive documents never leave your computer.

How much can I reduce my PDF file size?

The reduction percentage depends on the images and fonts in the PDF. PDFs with high-resolution images can often be reduced by 50% or more.
