Keep the sound, drop the picture. Pick a video from your phone, a screen recording, a webinar or a class, choose the audio format you need, and download an audio file a fraction of the size. MP4, MOV, WebM, MKV and AVI all work, and the video is converted on your own device.
Your file never leaves your device. Nothing is uploaded.
