Frequently Asked Questions
Are my PDF documents uploaded to any remote server?
Absolutely not. All modifications, annotations, page operations, and encryptions occur client-side in browser memory.
How does password protection and metadata removal work?
We leverage pdf-lib directly inside browser web-workers to rewrite metadata streams and inject encryption dictionaries locally.
Does my work auto-save?
Yes, your progress is serialized and cached locally to IndexedDB to safeguard against browser crashes.
