How much can the compressor reduce my bundle size?

Usually a modest amount. The tool removes unused data and metadata but does not reduce image resolution, so scanned bundles and photographs shrink little.

Will compression remove the OCR text layer?

No. The OCR text layer is preserved at every compression level. The compressed bundle remains text-searchable in court PDF readers.

No. Compression runs entirely in your browser. Your bundle never leaves your device — important for legal professional privilege and client confidentiality.
