Quick answer
How do you trim an audio file online?
To trim an audio file online, load it into the tool above, drag the start and end handles on the waveform (or type the times), press Preview, then Download WAV. The cut runs in your browser, so the file is never uploaded. It's free with no account. Files can be up to 60 MB, about an hour of 128 kbps MP3, and the download is always a WAV, not an MP3.

Tips
Cleaner cuts
Small habits that stop a clip sounding chopped.
Start the cut in a quiet moment between words or beats.
Use Last 3 s to hear the ending without playing the whole clip.
A fade of 0.1 to 0.3 seconds hides a click at the cut point.
On long files, drag close to the spot, then use the arrow keys for 0.1 s steps.
Only cut audio you have the right to use.
FAQ
Audio Trimmer questions
10 questions
How do I trim an audio file for free?
Load it into the trimmer at the top of this page, set the start and end, then press Download WAV. It's free, with no account and no watermark.
Link to this answerIs my audio uploaded?
No. Your browser decodes the file and cuts it on your device, so the audio never reaches our servers.
Link to this answerCan I download the trimmed clip as an MP3?
No, not here. The trimmer only exports WAV, because browsers don't include an MP3 encoder and this tool doesn't add one. If you need an MP3, open the WAV in our M4A to MP3 converter, which reads WAV files up to 60 MB.
Link to this answerDoes trimming reduce the quality?
The kept part isn't compressed again, because WAV is uncompressed. It's saved at 16-bit, and at your browser's audio rate, which is often 44.1 or 48 kHz. An MP3 opened here won't gain quality from becoming a WAV, though: it just becomes a bigger file.
Link to this answerWhy is my trimmed WAV bigger than the original MP3?
WAV is uncompressed. A stereo clip at 44.1 kHz takes about 10.6 MB per minute, while a 128 kbps MP3 takes about 1 MB per minute.
Link to this answerWhat formats can it open?
MP3, WAV, M4A and OGG usually work. The browser does the decoding, so what opens depends on the browser you use. For audio inside a video, use the extract audio from video tool first.
Link to this answerCan I use it as an MP3 cutter or audio cutter?
Yes for the cutting: an MP3 opens fine and you can cut any part of it. The result downloads as a WAV rather than an MP3.
Link to this answerHow do I cut a ringtone from a song?
Press 30 s clip to set a 30-second selection, move the handles to the part you want, add a short fade out and download. Apple's limit for iPhone ringtones is 30 seconds. Use only audio you have the right to use.
Link to this answerHow big a file can I trim?
Up to 60 MB. On a Windows desktop in Edge, a one-hour 128 kbps MP3 of 57.6 MB opened in about 5 seconds. We haven't measured phones, which have less memory, so long files may fail there. If one does, try a shorter file.
Link to this answerCan I remove a section from the middle?
No. This tool keeps one continuous section, from the start handle to the end handle. To join two parts, use an audio editor such as Audacity.

What works, what to avoid, and how the pieces fit.

What happens to your file
When you choose a file, the browser reads it from your disk and decodes it into raw audio in memory, using the Web Audio API [1]. The waveform, preview and export all work from that decoded copy. No part of it is sent anywhere, and closing the tab clears it.
Decoding is also why there is a size limit. The tool holds uncompressed audio in memory, so a small MP3 can become a very large buffer: an hour of stereo takes well over 1 GB as decoded samples. The tool stops at 60 MB for that reason.
How long big files take
We timed the tool on 4 November 2026 in Edge on one Windows desktop, using generated test tones. Your times will differ, and we haven't measured phones or other browsers.
- One-hour MP3, 57.6 MB at 128 kbps — opened in 4.6 seconds. Exporting almost all of it took 3.4 seconds and made a 634.6 MB WAV.
- 5 minute 40 second WAV, 60 MB — opened in 0.3 seconds and exported in 0.4 seconds.
- Anything over 60 MB — refused with a message, before it's read.
Why the download is a WAV
Browsers can decode MP3 but don't come with a way to write one, so an MP3 export would need an extra encoder inside the page. This tool doesn't have one, and it won't pretend to. WAV is plain uncompressed audio, which also means your cut isn't compressed a second time.
The catch is size: about 10.6 MB per minute for stereo at 44.1 kHz. That's fine for short clips, and the tool shows the size before you download.
Picking a clip length
Common lengths, and a button to start from:
- 15 seconds — a short social clip or a voicemail greeting.
- 30 seconds — a ringtone. Apple's iPhone limit is 30 seconds [2].
- 60 seconds — a longer social clip or a sample to send someone.
