You can upload a file size of 1MGB in the format of PNG or Jpeg not a PDF. This file size is required so your Klub admins can download the report of all members registered with the documents required. I file larger than this will would result in to much data and inefficient reporting.
A red text will appear if you are required to upload or amend an upload attempt.
