How Local PDF Compression Works
PDF files contain text streams, fonts, vector paths, and raster images. The compressor optimizes the document's structure in three distinct ways: Lossless optimization, recommended downscaling, or extreme compression.
Understanding the Compression Options
ZeroWebTools offers three custom compression settings to fit your needs:
- Balanced Compression (150 DPI)—Best sweet spot for standard files, downscaling images to 150 DPI at 70% quality.
- Extreme Compression (100 DPI)—Downscales images to 100 DPI at 40% quality, useful for government upload portals.
- Lossless Optimization—Cleans structural streams and strips useless metadata while keeping images intact.
Offline Security & Privacy
Since all file rendering, downscaling, and compression calculations execute locally, your documents are completely safe and secure.
