How to cut an audio file

Choose one local audio file. Drag the edges of the highlighted waveform region to select the section you want to keep, or enter its start and end times in seconds. Select Cut, then download the MP3.

Cut the opening silence from a voice memo, keep one passage from an interview, lecture or podcast, or use this music cutter to shorten a track. The download contains only the selected continuous range. The tool does not detect silence or speech for you, so listen to the result before sharing a time-sensitive excerpt.

An MP3 cutter online for WAV, M4A and other audio files

The picker accepts MP3, WAV, M4A, FLAC, OGG and other listed audio formats. Your browser must first decode the file to display its waveform. If that succeeds, cutting still needs an available conversion path. An MP3 source keeps its original bitrate: the tool cuts the selected range without re-encoding it. Every other format is converted to a new MP3 at 192 kbps.

Set the range on the waveform or by time

Drag the region edges for a visual cut, or type decimal start and end times in the fields below the waveform. The fields and region update together. The input fields support keyboard editing, but the downloaded cut may not land on a sample-exact boundary.

One selected section per cut

This cutter keeps one range between a start and end time. To save two separate parts, cut and download each one separately. To put those downloads in sequence, use the audio joiner. This page does not trim video or import audio from a URL.

Free browser processing

As an audio trimmer online, it cuts on your device in the browser, without a file upload, signup or payment. Processing time and the size of file your device can handle depend on its available memory and the source format.

Need a transcript instead?

You can send a supported recording to Hushscript transcription for a transcript, with optional speaker labels. That separate service uploads prepared audio and requires an account. Eligible personal accounts can receive 30 free minutes once after successful card verification, or with their first purchase if not already granted.

Frequently asked questions

How do I trim an MP3 or other audio file?

Choose a file, drag the edges of the highlighted waveform region or enter start and end times in seconds, then cut and download the selected section as an MP3.

Can I cut an MP3 audio file?

Yes, if your browser can decode the MP3 to show its waveform. The picker also accepts WAV, M4A, FLAC and OGG, but each file must first decode in your browser; cutting then depends on an available conversion path. The download is a new MP3.

Does cutting audio online upload my file?

No. The cutter processes your file in your browser and downloads the result to your device. Transcription is a separate service that uploads prepared audio.

Is this audio cutter free?

Yes. Cut and download as many times as you like: no signup, no payment. Large files may still be limited by your device's memory and the source codec.

Can I set a precise start and end time?

You can drag the waveform edges or type decimal seconds in the start and end fields. Check the downloaded MP3 by listening to it if the cut point matters; the tool does not promise sample-exact boundaries.

Can I remove a section from the middle?

The cutter keeps one continuous range. It cannot remove the middle and join the two remaining parts in one cut.

Can I transcribe the trimmed audio?

Yes, through the separate Hushscript transcription service. It uploads prepared audio and requires an account.

Need the words? Transcribe it with 30 free minutes

Preview up to 5 minutes before you create an account, and a new personal account gets a free preview of its first upload in the app. Full transcription needs an account and minutes; eligible personal accounts get 30 free minutes once, after card verification or with a first purchase. No subscription.
