Errors occur while trying to convert password-protected documents or archives. 2. Experiencing problems when converting password-protected files or archives. 3.

Dissatisfaction with the upload speed when attempting to convert large files (usually video). Please note that upload speed is beyond our control and depends on your internet connection's upload bandwidth or your internet service provider's (ISP) capabilities. 6. Disliking the service or no longer requiring it. 7. Having already converted a file larger than the free tier permits and downloaded the result, as this indicates that you have utilized the paid service. 8. Dissatisfaction with the features provided by our service or the absence of specific features. 9. Finding another service that you prefer. 10. Failing to cancel your subscription before the automatic renewal occurred. We strongly recommend testing the free version of our service before purchasing any premium package.
