How much can I compress a PDF?

PDFs with many images can typically be reduced by 40–90%. Text-only PDFs compress by a smaller amount depending on embedded metadata.

Will compression affect image quality?

It depends on the preset. 'Best quality' preserves visual quality while reducing file size. 'Smallest size' achieves maximum compression with a slight reduction in image resolution.

How do I reduce PDF size without losing quality?

Choose the 'Best quality' preset. This cleans the document structure and recompresses images efficiently while preserving visible quality.

Will the compressed PDF have a watermark?

No. PDFNexus does not add watermarks to any processed files.
