What does PDFDig store in my browser?
Preferences and optional history — never your file contents.
Updated May 21, 2026
PDFDig can store a few small things locally to improve your experience, all on your device:
- Preferences, such as theme and whether local history is enabled (LocalStorage).
- Recently used and favorite tools (LocalStorage).
- Optional history of tool runs — metadata only, like the tool name and time, never the file itself (IndexedDB).
Local history is off until you turn it on, and you can clear all local data at any time from the dashboard.
