Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To use the Audio Cutter, load one audio file, then set the start and end time for the part you want to keep. The tool isolates that range and lets you export it as a new, shorter file without affecting the original on your device.
You can export the clip as MP3, which is the default and plays everywhere, or trim supported files back out in their original format when you want to preserve the source codec. Both options run entirely in your browser.
People often just need to cut one audio file, regardless of whether it came from a voice memo, recording app, lecture export, or messaging app. A broader cutter that accepts M4A, MP3, WAV, AAC, and OGG matches that real-world workflow better than a format-specific page alone.
Because the cut happens locally, your recording never leaves your computer. That privacy matters for interviews, voice notes, and personal audio, where uploading a file to a server is exactly what you want to avoid.
Short answers for the questions people usually have before trying a utility like this.
Yes. MP3 is the default export, and supported files can also be trimmed back out in their original format so you keep the source codec when you need it.
The Audio Cutter accepts M4A, MP3, WAV, AAC, and OGG files as its main inputs, covering most voice memos, recordings, and downloads.
Yes. The clip is cut and exported entirely in your browser. The audio file is never uploaded to a server, so your recording stays on your device.
Yes. The Audio Cutter is free to use with no signup and no watermark, and it runs locally so there is no upload queue or account needed.
Every tool on Cleanor is free with no sign-up, no credits, and no limits. Files are processed privately in your browser. Looking for on-device phone cleanup and Premium features? That lives in the Cleanor app.
