The disclosure discloses methods and systems for automatically generating multiple scanned files when scanning a document at a multi-function device. The method includes receiving a multi-page document for scanning from a user. A user interface is provided to the user to input one or more keywords and one or more desired resolution values, where the input resolution values are different from a default resolution value set at the multi-function device. A page of the document is scanned to generate a scanned page of a default resolution value. The scanned page is checked if including the one or more input keywords. Accordingly, the default resolution value of the page is converted to the user desired resolution value. The scanning, checking, and converting are repeated till all the pages of the document are scanned. Multiple scanned files of different resolution values are automatically generated from single scan activity.
