PDF compression is executed securely on your private server using Ghostscript.
Native Ghostscript Compression
This utility employs a high-performance backend Ghostscript integration for intelligent image downsampling and structural optimization. Files are stored momentarily as transients and are deleted immediately after processing to ensure data security.
Lossless Optimization
Packs cross‑reference streams and objects. Zero effect on layout or print quality, keeping text crystal-clear. 5–30% savings.
Smart Balanced Mode
Tries lossless first, then applies image compression with adaptive DPI if the PDF contains heavy images. 30–70% savings.
Maximum Compression
Aggressive DPI and quality reduction for scanned docs and photo-rich files. Memory-safe chunked processing for large PDFs. 60–90% savings.
