How to convert video to MP3 on iPhone
Extracting audio saves the sound as a separate file; it does not keep the video's picture. This can be useful for a spoken clip or other audio you can use. Keep the original video if you may need its visuals later.
Convert a local video to MP3 in ClipKit
- Open ClipKit and import one compatible video from Photos or Files.
- Open the output format picker and select MP3.
- If you need only part of the audio, open Trim and set the section before converting.
- Tap Convert, then save or share the resulting audio file using the available iOS options.
Other audio output formats include M4A, WAV, AAC, AIF/AIFF, FLAC, and OGG. Choose MP3 when the destination asks for it; check the destination's accepted formats if unsure.
Check the saved audio
Play the saved MP3 in Files or another audio player before deleting the source. In one isolated iPhone Simulator QA run using a licensed 6.07-second test video, the exported file was audio-only MP3 at 48 kHz stereo, 6.016 seconds, and 145,863 bytes. It decoded with non-silent audio. This is one test result, not a size or quality prediction for other videos. The in-app result screen did not include an audio player.
The measured audio was slightly shorter than the 6.067-second source video. Trim points, encoding, and source content can affect the result; listen through the part you need.
