Transparent Privacy & Data Safety
We believe users deserve complete transparency regarding how their documents are handled:
Client-Side Utilities: The majority of PDFHub tools (including Merge, Split, Compress, Rotate, Watermark, Sign, Redact, and office conversions) process documents strictly in your local browser memory using JavaScript and WebAssembly. No copies are ever transmitted to or stored on remote servers.
Network-Dependent Intelligence: Tools that require machine learning models (such as AI Document Summarizer and Live Translation) extract document text locally before securely communicating with translation or language inference endpoints to generate output.
