🎵 Audio Clipper
Upload audio files, select start and end times to trim segments, and export as WAV format. All processing happens in your browser—files never leave your device.

Sample-accurate cut points, why the exported file is always 16-bit WAV, what the trimmer cannot do — and why an autocorrelation BPM detector keeps handing you double the tempo you expected.
Cutting a clip
Load a file and it is decoded and drawn as a waveform straight away. The start and end of the selection can be set either by typing a time or by dragging the two sliders, and the highlighted region on the waveform shows exactly what will be exported. The range readout and duration update as you go, so you can see the length of the clip before committing to it.
The preview button plays the selection rather than the whole file, which makes it practical to find an exact boundary by ear: nudge the edge, play again, and stop when the clip begins and ends where you want it to. Stop interrupts playback without losing your selection.
Cut points are taken at sample resolution rather than rounded to the nearest frame or tenth of a second, so the boundary lands where you put it. That matters if you are trimming to a beat: a clip that starts a few milliseconds late is audibly late when you loop it.
What the exported file is
The download is always a WAV file, 16-bit PCM, at the original sample rate and channel layout — a stereo 44.1 kHz source comes back as stereo 44.1 kHz. Nothing is resampled, and the only loss is the reduction of the sample values to 16-bit integers, which is what most consumer audio is stored at anyway.
One thing to plan for is size. WAV is uncompressed, so a stereo file at 44.1 kHz costs roughly ten megabytes for every minute of audio — five for mono, and correspondingly more at higher sample rates. A three-minute clip is about thirty megabytes. That is normal for the format and not a sign that something has gone wrong, but it is worth knowing before you export an album side.
If the source was a lossy format such as MP3 or M4A, the exported WAV is a faithful copy of what your browser decoded — the compression damage was already done when the file was created, and re-exporting as WAV cannot undo it. It does mean, though, that cutting and re-exporting will not make things noticeably worse, which is not true of cutting and re-encoding to a lossy format.
Files, limits and privacy
MP3, WAV, FLAC, OGG, M4A and AAC files up to fifty megabytes are accepted, and the format is checked by both its declared type and its extension. Decoding starts automatically on upload, so a large file begins working before you do anything else.
Everything happens in your browser. The audio is decoded by your own machine and the exported file is built there too, so nothing is uploaded and nothing is stored anywhere. What that buys you in privacy it costs in memory, since a long lossless file has to be held in full while you work on it — if a large file behaves sluggishly, that is why.
FAQ
Can I export as MP3 instead of WAV?
No. The export is WAV, which is uncompressed and lossless but large. Converting to MP3 needs an encoder and is a lossy step, so it is normally better done at the end of your workflow rather than here.
Why is the downloaded file so big?
WAV stores every sample uncompressed. A stereo file at 44.1 kHz takes about ten megabytes per minute, so a three-minute clip is around thirty megabytes. That is the format working as intended, not a problem with the export.
Will exporting reduce the quality of my audio?
The cut is sample-accurate and the sample rate and channel count are preserved, so the only change is quantising to 16-bit — a level of precision that most consumer audio already uses. If your source was already lossy, the export cannot undo that, but it will not add anything either.
How precisely can I place the cut?
To the individual sample, which is finer than any editor interface can show you. Typing a time gives you millisecond precision in the input; the cut itself is converted to a sample index, so nothing is rounded to a frame boundary.
What is the upload limit?
Fifty megabytes, in MP3, WAV, FLAC, OGG, M4A or AAC. Very long lossless files can be slow to work with because the whole decoded audio is held in memory, but nothing is rejected for being long, only for being large.
Is my audio uploaded to a server?
No. Decoding, previewing and export all happen in your browser, and the file never leaves your device. The download is produced locally and saved straight to your computer.
