Ratings and reviews

Very excellent batch video to audio converter!! While other apps of the same Ilk require you to pay for batch mode....this is absolutely free!! Sure it's not as pretty as the other apps, but it sure gets the job done!! I Like how it operates in the background! Can't ask for anything better for what I use it for!! Great job!!

This app it's absolutely amazing. I'm a researcher and I record around 100 wav audio files/day which I convert with this app. The speed of conversion is amazing, it never gave an error after thousands of conversions, unlike other apps I tried you can connvert unlimited number of files at once and it doesn't have almost ads. Very simple, very powerful and easy to use. I truly thank you for this.

This app just works. I extracted MP3 audio from 75 (approx. 3GB, 9 hours) MP4 files. Original audio was 164kbps, I compressed to 64kbps during extraction and the whole process took 20 mins give or take on my lower end Moto G. Best part, no uploading required, this app did it all on my device. Very Happy
