Want to save the audio from a video on your iPhone? Whether you're turning a lecture into a podcast, saving a speech to listen to later, or extracting music from a video you own, you can convert a video's audio into an MP3 file in just a few taps.
With Documents by Readdle, you can extract audio from videos stored on your iPhone, in the Files app, or in cloud storage—without modifying the original video.
Why extract audio from a video?
Extracting audio lets you:
- Listen to lectures or interviews without watching the video.
- Save speeches or presentations as audio files.
- Create podcasts from recorded videos.
- Free up storage by keeping only the audio when you no longer need the video.
- Listen offline while commuting, exercising, or traveling.
