2026 privacy posts praise browser tools that process PDFs with WebAssembly so files "never hit a server." That is a real improvement over classic upload sites - and still not the same as a desktop app.
Honest comparison
- Upload sites - convenient, weak privacy for Aadhaar / statements.
- In-browser local tools - better privacy; limited by tab memory, OS quirks, and "did this page change?" risk.
- Desktop offline editor - repeatable workflow, batch-friendly, works when the network is bad.
