About Trim Audio
Trim Audio is a free online audio cutter that keeps the section of an audio file between a start and end time. Upload an MP3, WAV, M4A, AAC, OGG, FLAC or Opus file, type the two times, and download the cut clip in the same format you started with — so a WAV stays a WAV and an MP3 stays an MP3.
Everything runs on an in-browser build of ffmpeg, which means your file is cut on your own device and never uploaded to a server. There's no account, no watermark on the result, and no limit on how many files you cut, so it handles the everyday job of shortening a track or lifting one part out of it — a free alternative when you'd otherwise reach for an upload-based cutter like Clideo or Flixier.
Because it's a web page rather than an installed app, the same audio cutter opens on a laptop, an iPhone or an Android phone straight from the browser — handy for cutting a ringtone, a voice memo or a podcast clip on your phone with nothing to download from an app store. Enter times as plain seconds (30) or as minutes and seconds (0:30), and the tool keeps everything between them. Since the processing happens locally, nothing you cut ever leaves your device.
Frequently asked questions
- Is it free to use?
- Yes — it's completely free with no sign-up, no watermark, and no limit on how many files you cut.
- Can I cut an MP3 online?
- Yes, that's the main use. Upload the MP3, set a start and end time, and download the shortened MP3 right in the browser tab, with nothing sent to a server.
- Can I use it as a WAV cutter?
- Yes. Load a WAV, set the range, and the trimmed file downloads as a WAV, keeping the same uncompressed format you uploaded rather than switching to MP3.
- Is my file uploaded to a server?
- No. It runs an in-browser build of ffmpeg, so your file is processed entirely on your own device and never uploaded.
- How do I set the start and end?
- Enter the times as seconds (e.g. 30) or minutes and seconds (e.g. 0:30). The tool keeps everything between them and discards the rest.
- Which audio formats are supported?
- Common formats including MP3, WAV, M4A, AAC, OGG, FLAC and Opus. The trimmed file keeps the original format.
- Can I cut audio on my phone or an Android device?
- Yes. It's a web page, not an app you install, so it opens in the browser on Android and iPhone as well as on a computer. There's nothing to download from an app store — just open the tool and cut.
- Can I cut the audio from a YouTube video?
- No — the tool can't download anything from YouTube, and it only works on a file that's already on your device. If you have the audio saved as an MP3 or another file, upload that and set your start and end times.
- Can I turn a video into a cut MP3?
- This tool works with audio files, so it won't open a video such as an MP4 directly. You'd first need the audio as a separate file (MP3, M4A, WAV and so on), and then you can trim it here.
- Is this a free alternative to Clideo or Flixier?
- Yes, for the everyday cutting job. It trims an audio file to a start and end with no sign-up and no watermark on the result, and unlike upload-based editors it keeps the file on your own device.
- Does the cut file have a watermark?
- No. The audio isn't watermarked in any way — the download is simply your original file trimmed to the range you chose.
- Why does the first run take a moment?
- The first time, it downloads a ~32 MB processing engine. That's cached afterwards, so later runs start instantly.
