Currently, Ithmb Viewer supports converting one file at a time; open and convert each file individually for batch processing.

Basic viewing and conversion features are free; check the settings menu under 'Account' or 'Subscription' for premium options if available.

Go to Settings > Account > Subscription to view plans and follow the prompts to subscribe or upgrade to premium features.
