How does Any2File protect my privacy with Lock PDF?

All algorithms execute locally on your device within your browser sandbox using compiled WebAssembly and native Web APIs. Your files, documents, and inputs never touch external cloud servers.

Are my confidential PDF documents uploaded to a cloud server?

No. All document parsing, rendering, and conversion occurs entirely within your local browser sandbox using client-side WebAssembly and JavaScript engines. Your documents are never uploaded, logged, or inspected by Any2File or third parties.

Does PDF conversion preserve formatting, fonts, and images?

Yes. Our engine extracts text streams, embedded vector paths, font glyphs, and raster image layers with high fidelity, ensuring typography and layouts mirror the original document.

What is the maximum file size limit for PDF processing?

Because processing executes client-side on your device rather than a metered server, you can process documents up to hundreds of megabytes, limited only by your available browser RAM.

This architecture achieves sub-second execution speeds, bypasses network upload bottlenecks, and adheres to strict enterprise privacy standards including GDPR and HIPAA confidentiality guidelines.
