How much can I reduce my PDF size?

Typical compression reduces file size by 40-70% depending on the content. PDFs with many images see the largest reductions, while text-heavy documents may have modest gains.

Will compression affect my PDF quality?

Our "High Quality" setting preserves visual fidelity while reducing size. For documents with important images, we recommend this setting. Maximum compression is ideal for sharing via email.

PDFs containing high-resolution images, scanned documents, and embedded fonts typically see the best compression results. Vector graphics and text compress efficiently with minimal size reduction.
