Converted a format I'd never heard of

Random .3GP files from an old phone — nothing would open them. Profi PDF nailed it in under a minute. Genuinely impressed.

YouTube finally accepted my uploads

Format errors every time I tried uploading screen recordings. Profi PDF converted them to MP4 and they went through first try. Just works.
