Upload documents

I created a PDF converter application that provides two main functionalities. In the first option, the user can upload a PDF file, and the system will convert all its pages into images. In the second option, the user can upload an image, which will then be converted into a PDF file. Once the file is uploaded, it is processed through a servlet that handles the conversion logic in both cases. After the conversion is complete, the user is provided with a direct option to download the converted file, ensuring a smooth and user-friendly experience for managing file formats.
