Video to MP3 and MP4 to MP3: Extract Audio From Video on Phone

To extract audio from a video on Android or iPhone, convert the video to MP3 in ResizePing: pick the video, tap Make MP3 and the sound is saved as an MP3. To convert a video to MP3 or turn an MP4 to MP3, open ResizePing, pick a video from your phone, optionally trim the start and end, choose an MP3 bitrate, and extract the audio track to an MP3. Whether your source is an MP4 or another video, the flow is the same: video file in, MP3 out. The app includes a built-in player to preview the result, and stores completed files in History. You should only convert videos you have the right to use.

Quick steps

Follow these steps to extract an MP3 audio track:

Open ResizePing on Android or iPhone and select the video to MP3 tool.
Pick a video from your phone library.
Optionally trim the start and end of the clip if you only need a portion of the audio.
Choose an MP3 bitrate: 64, 96, 128 (default), 192, or 256 kbps.
Tap Make MP3 to extract the audio track to an MP3.
Preview the result with the built-in player, or open History to find past conversions.

Video to MP3 extraction options

These are the controls you get when extracting audio in ResizePing.

MP4 to MP3 and supported video types

Users often search for ways to convert MP4 to MP3 because MP4 is the standard format for phone camera recordings and downloaded video clips. In ResizePing, converting MP4 to MP3 follows the exact same flow as any other video conversion: you provide a video file as input, and the tool produces an MP3 file as output.

Other videos follow the same steps. Videos with no audio track or unsupported audio show an error.

Trimming start and end points

Video recordings often have silence or unnecessary footage at the beginning or end. You can trim the start and end points before converting. Setting trim points ensures only the desired audio segment is converted to your finished MP3.

Built-in player and history

Once the audio track is extracted, you can check it right away. ResizePing includes a built-in player on the result screen so you can listen to the audio track right away. Results are kept in History, making it straightforward to review or play your previous audio files whenever you need them.

Choosing your bitrate setting

Bitrate measures the data processed per second of audio, expressed in kilobits per second (kbps). ResizePing offers five bitrate options: 64, 96, 128 (default), 192, and 256 kbps.

Consider these guidelines when selecting a bitrate:

64 kbps and 96 kbps: Lower bitrates produce smaller files. They are well suited for spoken voice, lectures, voice memos, and meetings where vocal clarity is needed rather than musical depth.
128 kbps (default): The default setting balances sound clarity with compact file weight. For standard video clips, speech, and general listening, 128 kbps is a practical baseline.
192 kbps and 256 kbps: Higher bitrates preserve more acoustic detail. Pick 192 or 256 kbps for music recordings, live performances, or environmental audio where subtle frequencies matter.
