How does CookPDF process PDF files?

Standard PDF tools perform the main operation directly on your device. The browser may store a local cache for session recovery.

When is data processed by CookPDF's AI?

Only when you actively use an AI feature such as Q&A, summarize, translate, or generate questions from a PDF.

Can I delete a saved session?

Yes. Delete it or start over in the interface; you can also delete CookPDF website data in your browser settings.

Does CookPDF work on phones?

Yes. CookPDF works on desktop, tablet, and mobile browsers. Large files may be handled more comfortably on devices with more memory.

Do I need to log in?

Some tools can be used without logging in. An account or service plan is only required when the function's interface clearly states so.
