Prefer a Desktop App? Meet PdfHub Local
The same PDF Hub toolset is also available as PdfHub Local — a native Windows desktop application that runs entirely on your own machine. Your files are processed locally and never uploaded, so it’s ideal for confidential documents, batch-processing whole folders, and working offline. It’s built on the same Adobe PDF Library engine as the online Hub, so the output is identical. Read more about PdfHub Local.
Private & Offline
Files are read and written on your own disk and never leave your computer. Work without an internet connection — ideal for sensitive documents.
Fast & Batch-Ready
No upload/download round-trips and no file-size limits. Point it at a folder to process every file at once, or chain steps into reusable workflows.
The Full Toolset
Convert, merge, split, compress, OCR, watermark, redact and sign — the same tools you know from the web Hub, with a visual Page Manager and in-app preview.
Free 14-day trial — every tool unlocked, no account needed to start. Then included with any paid PDF Hub plan. Windows 64-bit.
Deploy PDF Hub on Your Own Infrastructure
For organizations where document confidentiality is paramount, the Mapsoft PDF Hub is available for on-premises installation. PDF Hub is a .NET web application that runs on Windows servers, wrapping the Adobe PDF Library using technology developed by Datalogics — Adobe’s long-standing partner in developing and supporting the PDF Library. It is available with a web-based user interface for interactive use, and most of its functionality is also accessible as a REST service for integration into your own applications and workflows. By deploying PDF Hub on your own infrastructure, you maintain complete control over your data — sensitive PDF files never leave your network.
This is particularly valuable for legal, financial, healthcare, and government organizations that must comply with strict data handling regulations, or for any business that simply prefers to keep its documents in-house.
Full Data Sovereignty
Your PDF files stay on your servers. No documents are uploaded to external services — eliminating confidentiality concerns entirely.
Powered by Adobe PDF Library
PDF Hub uses the Adobe PDF Library — the same core engine that powers Adobe Acrobat. Mapsoft is an OEM licensee with over 20 years of experience using this library, and receives updates on an almost monthly basis.
Current PDF Standards
Unlike third-party PDF libraries, the Adobe PDF Library is developed in parallel with Adobe Acrobat and maintains the most current PDF standards — giving you confidence in accuracy and compatibility.
