Slow file upload

There are several possible reasons why you may experience slow file upload times in the virtual classroom:

1. The file is too big or contains lots of images;
   In this case, the only thing to do is wait for the converting process to finish.
2. Slow internet connection;

3. You’ve set password protection for your file;
   You will not be able to convert a file with a password set. Please, remove password protection from the file and try uploading once again.
4. The system does not support the file format you are using.
