FAQ
Will compression make my text blurry?
No — text in a PDF is vector data, not an image, so compression targets embedded images and structure without degrading text sharpness.
How much smaller will my file get?
It depends heavily on how image-heavy the original PDF is; text-only PDFs were already small and won't shrink much, while scanned/image-heavy PDFs often see the biggest reduction.
