Compression results depend on PDF content. Image-heavy PDFs can be reduced by 50-80%. Text-only PDFs have less room to compress. Maximum mode gives smallest file size.
Higher compression means smaller files but lower image quality. "Low" compression maintains near-original quality. "Balanced" is recommended for most use cases.
No. All compression happens in your browser. Your files never leave your device.
