Google is updating AI Mode to add support for PDF uploads on desktop, which could help you digest lengthy course or work materials.

The PDF to PNG tool is a specialized software or web-based application that allows users to convert pages of a PDF document into PNG format.

Instead, upload the image to Google Drive. Before you do this, make sure the image is the right way up. Then, sign in to Google Drive, and click and drag the file to the relevant Google Drive folder.
