Photos can be taken directly with the in-app camera and converted into many different formats.
Your converted files are clearly stored in the app so that they can be accessed at any time.
All of your converted files will be converted locally and will stay local. The app doesn't need any internet access, so your private files stay private.
Several types of images, videos, and documents are currently supported. However, further formats are still being worked on. A list of currently supported file formats can be viewed here
