Finally got my old home videos on my phone

Had years of family videos stuck in AVI that nothing would play. Cacao Docs converted them all to MP4 and now they're on my phone and backed up to the cloud. Priceless.

YouTube stopped rejecting my uploads

Was uploading AVI files to YouTube and kept getting format errors. Cacao Docs converted them to MP4 and everything went through first try. Should've done this ages ago.

Fast, clean, no watermarks

Converted a big batch of old AVI clips in one session. Cacao Docs was fast, the quality held up perfectly, and there was no watermark or sign-up wall. Exactly what I needed.
