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.

No sign-up, no watermark, perfect
Every other site wanted my email or slapped on a watermark. Profi PDF just converted and let me download. Bookmarked for life.
