Saved years of old Flash videos
Had a hard drive full of FLV files from the early 2000s that nothing would open. PDF Paw converted them all to MP4 and I can finally watch them again. Absolute legend of a tool.

YouTube finally accepted my uploads
Was trying to upload old FLV recordings to YouTube and kept getting rejected. PDF Paw converted them to MP4 and they went through first try. Should've found this sooner.

Fast, clean, no watermarks
Converted a batch of old FLV clips in one go. PDF Paw was quick, the quality was solid, and there was no watermark or sign-up required. Exactly what I needed.
