Audio Trimmer
Trim audio files in seconds: load a track, set start and end on its waveform, preview before saving — exports WAV entirely in your browser, no uploads.
Drag your audio file here or click to choose
Supported input formats depend on what your browser can decode. The output is always uncompressed WAV; long clips produce larger files, which is expected.
🔒 Your audio file never leaves the browser — all processing happens on your device, nothing is uploaded to any server

Frequently Asked Questions
Which audio formats does the tool support?
Anything your browser itself can decode — usually WAV, MP3 and Ogg Vorbis, and often M4A/AAC on modern browsers. We verify the file before decoding regardless of its name, and if the browser can’t read it we tell you plainly rather than claim support for a format we can’t handle.
Why is the output always WAV?
Because uncompressed PCM WAV is the dependable, fully deterministic way to export decoded audio in the browser. The MediaRecorder path records in real time and produces whatever format suits the browser (usually WebM/Opus), so results differ across browsers. WAV works everywhere, with one clear price: large files for long clips. We say so rather than hide it.
What does "uncompressed" actually mean?
Every audio sample is stored exactly as-is at 16-bit precision, with no compression and no loss. That reliability is what makes it trustworthy, but it means a larger file than MP3 for the same duration. It’s ideal for short clips; for very long ones the file gets big, which is expected.
Can I preview the trim before saving?
Yes. Once you set the start and end points, the play button plays back exactly what will be exported — the same sample boundaries that will land in the WAV file, so you never save first and discover the problem after.
What resolution does the output have?
The original file’s sample rate at 16-bit depth. We don’t change quality or add anything — we only cut along the timeline, precisely at sample boundaries.
Is my file uploaded to a server?
No, not for a moment. All processing — decoding, waveform drawing, trimming and exporting — happens entirely inside your browser, your file never leaves your device, and there are no daily limits.
