Trim Audio Online with a Waveform Audio Cutter

Use this free online audio trimmer to cut the exact section you want from an MP3, WAV, M4A, AAC, OGG, FLAC, or WebM audio file. The visual waveform helps you find the right moment, while the start and end fields let you make precise cuts down to the millisecond.

Everything runs locally in your browser with FFmpeg WebAssembly. There is no file upload, account, or watermark: your recording stays on your device from selection to download.

How to trim audio online

  1. Choose your audio file. Drag it onto the page or browse from your device, then wait for the waveform to appear.
  2. Select the part to keep. Move the waveform handles or enter exact start and end times. Press play to preview only that section.
  3. Export the trimmed clip. Choose MP3, WAV, M4A, AAC, OGG, or FLAC, add an optional fade in or fade out, and select Trim Audio.

Make ringtones, podcast clips, and shorter recordings

An audio cutter is useful whenever you need one clean section from a longer file. Cut a song for a ringtone, remove silence from a voice memo, save a quote from an interview, create a podcast preview, or shorten narration before adding it to a presentation or social video.

Supported audio formats

The trimmer accepts MP3, WAV, M4A, AAC, OGG, FLAC, and WebM audio up to 500 MB. You can export the selected section as MP3, WAV, M4A, AAC, OGG, or FLAC. WAV and FLAC are suitable when you want lossless output; MP3, M4A, AAC, and OGG create smaller files for sharing.

Need a different format first? Use the online audio converter. If the sound is inside a video, start with Extract Audio from Video.

Audio Trimmer FAQ

How do I trim an MP3 online?

Choose the MP3, drag the two waveform handles around the section you want to keep, preview it, and select Trim Audio. The new clip is processed in your browser and becomes available to download.

Which audio formats can I cut?

You can trim MP3, WAV, M4A, AAC, OGG, FLAC, and WebM audio. Export options include MP3, WAV, M4A, AAC, OGG, and FLAC.

Does trimming audio reduce its quality?

Compressed outputs such as MP3 and M4A are re-encoded, so some quality change is possible. Choose WAV or FLAC for lossless output. Converting an already compressed source to a lossless format prevents another lossy encode but cannot restore quality that was previously removed.

Can I make a ringtone with this MP3 cutter?

Yes. Select a short section of the song, add brief fades if desired, and export it. Your phone may require a particular format or duration, so check the ringtone requirements for your device.

Is my audio uploaded or stored?

No. Waveform generation, preview, trimming, and encoding happen locally on your device. RizCraft does not receive or store the selected file.

What is the maximum audio file size?

The current limit is 500 MB. Very large files also depend on the memory available to your browser and device.
