Saved years of old Flash videos

Had a hard drive full of FLV files from the early 2000s that nothing would open. Cacao Docs 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. Cacao Docs 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. Cacao Docs was quick, the quality was solid, and there was no watermark or sign-up required. Exactly what I needed.
