Compress PDF FAQ

Will every PDF become smaller?

Not necessarily. Results depend on the source file, its images and any compression already applied. Review the reported size savings.

Does compression change quality?

It can reduce image sharpness, depending on your selected level. Inspect the downloaded PDF, especially pages with small print or detailed diagrams.
