PDF compression FAQ
Why can’t lossless compression guarantee a smaller file?＋
Some PDFs are already efficiently compressed. Rebuilding one may save little space—or occasionally create a slightly larger result—because visible content is not degraded.
What changes in the scan-focused modes?＋
Each page is rendered as a JPEG image. This often reduces scans significantly, but selectable text, hyperlinks, forms, layers and vector sharpness are flattened.
Which mode should I try first?＋
Start with Lossless for digitally generated files. Use Balanced for scans or photo-heavy PDFs when lossless optimization produces little improvement.
