How to trim audio online

  1. 1. Choose your recording

    Open an MP3, M4A or WAV file. The audio cutter reads the recording and builds a waveform so you can see where sound starts and stops.

  2. 2. Keep the part that matters

    Drag the start and end handles to remove an introduction, a long pause or an unwanted ending. Enter timestamps for finer adjustments, then preview your selection.

  3. 3. Trim, listen and download

    Choose an output format and trim your audio. Listen to the exported clip before downloading it for your next project.

Choose the right audio format

MP3
A compact choice for sharing voice clips, interviews and everyday listening. Exporting to MP3 may introduce some quality loss.
M4A
Useful for AAC audio workflows. Available when your browser supports AAC encoding; cropping a recording can require re-encoding.
WAV
Uncompressed audio for further editing. Files are larger, and exporting as WAV cannot recover detail missing from the original.

Make your recordings easier to use

Podcast and interview excerpts

Keep one answer or a short highlight instead of sharing the entire recording. Preview both ends so the speaker’s sentence stays intact.

Lessons and voice notes

Save the explanation you want to hear again. Cut away setup time and unrelated sections from recorded lessons or personal notes.

Prepare audio for transcription

Create a shorter file with just the relevant discussion. Download the clip, then select it in the transcription tool to turn speech into text.

Which audio formats can I use?

Can I remove a section from the middle?

This tool keeps one continuous selection and removes everything outside it. Removing a middle section and joining the remaining parts is not supported.

Does trimming preserve the original quality?

MP3 and M4A exports may re-encode the audio. WAV is uncompressed but does not improve the source recording. Listen to the exported clip before using it.
