Use a converter or take a screenshot
In Notud you can upload image files to a template or note, however if you have a PDF you would like to upload, here are some different ways you can convert the PDF to an image so it can be easily used:
1. Use a PDF converter
There are both free and paid options for converting PDFs in to image files.
A good one is Adobe as you can convert two files per day at a high quality for free without needing to create an account. Here is the link: https://www.adobe.com/au/acrobat/online/pdf-to-jpg.html
2. Screenshot
Use your computers snipping or screenshot tool to capture the full page of the PDF as an image.
