Audio Trimmer
The Audio Trimmer lets you cut an audio file to exactly the part you want — an intro, a loop, a chorus, or a clean section of an exported track — without uploading anything or installing software. Drop in an MP3, WAV, M4A, OGG, or FLAC, and the tool decodes it locally and draws a waveform so you can see the sound. Drag the start and end handles to frame your selection, preview just that region to check it, then download the trimmed clip as a high-quality WAV. Because everything runs in your browser with the Web Audio API, your file is never sent to a server — which matters when the track is unreleased. Trimming is the single most common thing creators need to do with audio: an AI-generated song often has a few seconds of lead-in or tail you want gone, a podcast needs its intro isolated, a video edit needs a loop cut to length, and a sampler needs a tight one-shot. Most free trimmers force an upload and stamp the result or cap the file size; this one keeps your audio on your machine, has no watermark, and accepts files up to 20 MB. It is built for speed: open it, drop a file, drag, download. If you generated a track with MusicGenerate and just need the best eight bars, this is the fastest way to get them. And because it is free, browser-based, and private, you can come back any time — no account, no install, and not a single upload.

Frequently asked questions
Is this audio trimmer really free?
Yes — completely free, no signup, no watermark, and no file limit beyond a 20 MB upload cap. It runs in your browser, so there is no server cost passed on to you.
Does my audio get uploaded anywhere?
No. The trimmer decodes and cuts your file locally using the Web Audio API. Your audio never leaves your device, which is important for unreleased tracks.
What formats can I trim?
Any format your browser can decode — MP3, WAV, M4A/AAC, OGG, FLAC, and more. The trimmed clip downloads as a lossless WAV.
Can I trim a song on my phone?
Yes. The trimmer works on mobile browsers; the waveform and handles are touch-friendly, and tap targets are sized for fingers.
Why does it export WAV instead of MP3?
WAV is lossless and instant to create in the browser without re-encoding. If you need MP3, run the WAV through the Audio Converter, or master it in your editor.
