Our verdict on HankPDF

HankPDF is an open-source PDF compression command-line tool for scanned documents, including medical and legal records. It processes files locally on Windows, macOS, and Linux, without network uploads or telemetry, and converts oversized PDFs into smaller, searchable documents. Its audience is privacy-conscious individuals, technical teams, and organizations handling document collections that need local processing rather than a browser-based workflow.

Its strongest area is scanned-document compression. MRC-based processing is paired with OCR text-layer extraction, producing searchable PDFs while retaining image content. Content-drift verification checks OCR, images, and document structure, and signature handling addresses signed PDFs. For larger collections, HankPDF can process directory trees with parallel jobs and split output by a maximum PDF size. These features give it a broader workflow than a simple file-size reducer, particularly for archives and records processing.

The surrounding ecosystem is suited to automation: HankPDF includes a Python compression API, a Docker image with native dependencies, and CLI usage across Windows, macOS, and Linux. It is distributed under the Apache-2.0 open-source license and can also run self-hosted. The trade-off is a command-line-first experience: there is no graphical interface or signed desktop installer. Teams wanting scriptable, local processing and document-preservation checks should consider HankPDF; users seeking a point-and-click desktop application should choose a tool built around a graphical interface instead.
