What happens to my files?

Converter Dragon reads the files inside your browser, creates downloadable converted files, and forgets them when you clear the queue or close the tab.

What does the optimizer do?

It removes unnecessary metadata and empty payload where possible, while keeping the original visible or audible content intact. It is meant to clean, not compress aggressively.

Which special conversions are included?

Image to PDF, video to audio, audio + image to video, and several document output formats are built in.
