Cut any audio file to just the part you need, using the waveform to find the exact start and end. Free, no sign-up, and your file never leaves your device.
Long audio files are hard to share. A voice note with thirty seconds of silence at the start, a song you only want the chorus from, or a recording with a mistake at the end all need the same fix: cut the good part out and keep the rest out. This free audio trimmer with waveform lets you do that in your browser, with no sign-up and no software to install.
The waveform is the key. It draws the loudness of your file as a shape, so silence looks flat and speech or music looks tall. You can see at a glance where the talking starts, where the applause ends, and where the dead air sits. Dragging the start and end sliders while watching that shape is far more accurate than guessing times from numbers alone.
How to trim audio in three steps
- Choose an audio file from your device. MP3, WAV and most common formats work.
- Move the start slider to where the good part begins and the end slider to where it stops. Play just that selection to check it.
- Press Download to save the trimmed clip as a WAV file on your device.
Everything runs on your own device. Your file is decoded in the browser and never uploaded to a server, so a private voice note stays private. The download is a standard WAV file, which opens in almost every audio player and editor, on phones and computers alike.
When a trimmed clip is useful
- Ringtones and alerts: cut the best few seconds of a song instead of hearing a long intro every time your phone rings.
- Voice notes: remove the silence before you started talking and the fumbling at the end.
- Podcasts and interviews: lift a short quote to share, without sending the whole episode.
- School and work: send only the relevant part of a lecture recording to a classmate or colleague.
A good habit is to leave a small margin. Cut a half second before the first word and a half second after the last one, so the clip does not start or end mid-syllable. Play the selection once before downloading; a cut that sounds abrupt in the preview will sound abrupt in the saved file too.
Honest limitations
First, the download is WAV, which is larger than MP3, because WAV keeps every sample without compression. That is good for quality and editing, but a long clip makes a big file. Second, this tool cuts; it does not remove background noise, boost quiet voices, or mix tracks together. Third, very long files take longer to decode, and old phones may struggle with recordings over an hour. For those, trim on a computer instead.
Finally, respect the audio you trim. Cutting a song for your own ringtone is one thing; sharing someone else’s music or a private recording without permission is another. Use the tool for your own recordings, your own music library, and clips you have the right to share.
Frequently asked questions
Does the waveform show the whole file?
Yes. The full file is drawn from start to finish, squeezed into the width of the tool. Zoom is not included, so for a very long file, small details blur together. For precise cuts in long recordings, trim in two passes: first cut a rough section, then trim that shorter clip again.
Will trimming reduce the sound quality?
No. Trimming only keeps a section of the original samples. It does not re-compress or filter the sound, and the WAV download preserves the samples exactly as decoded.
Is my audio uploaded anywhere?
No. The file is read and decoded inside your browser. Closing the page removes it from memory, and nothing is stored on our server.
