Compress Scanned PDF
Scanned PDFs are compression\'s best customer: scanners save pages at wild resolution with zero optimization, so 20MB files routinely become 2MB — readable, sendable, honest. We compress toward your target at the best quality that fits, never make the file larger than the original, and always show the real final size — very image-heavy files may land slightly above tight targets.

Why scanner files are so bloated
Scanners digitize at print-shop DPI, in full color, with no encoding intelligence — every page becomes a giant raw photograph of paper. Almost none of that data serves reading; compression resamples to what eyes and screens use.
Scan-specific wins
Grayscale conversion (most scans are monochrome documents anyway) and display-appropriate DPI stack multiplicatively — the honest route from scanner bloat to portal-ready sizes. KB targets aim the result precisely.
