Compress PDF
Reduce PDF file size by compressing images and cleaning up
How compression works: embedded images are re-encoded as JPEG at a lower quality, downscaled if larger than a per-level cap (1200/1800/2400 px), and the PDF's internal cross-reference table is cleaned up.
Best results on: photo-heavy PDFs (scanned reports, brochures, photo books). Minimal savings on: text-only PDFs — they're already tiny because text compresses well in PDF natively.
- Maximum compression — JPEG quality 40, max image edge 1200px. Best size, visible image quality loss.
- Medium — JPEG quality 65, max 1800px. Good balance for most use.
- Minimal — JPEG quality 85, max 2400px. Slightly smaller, hardly any loss.
Image positions, sizes, and rotation are preserved exactly — we replace each image in-place rather than re-flowing the page.
