Trim audio.
Never leave your browser.
Drop in a file or open a take from your local library, drag the handles or type exact times, then keep the part you want or cut a section out of the middle. Download a clean WAV when you're done.
Trim an audio clip
Checking local library…
No selection
No file loaded yet.
Drop an audio file or open one from your local library to start trimming.
Trimming a clip shouldn't require an upload
Most online trimmers work by uploading your file to a server, cutting it there, and sending back a link. This one keeps every step — decode, select, cut, encode — on your device.
Your file never leaves your browser
Decoding and trimming happen with the Web Audio API in this tab, nothing else.
Your local library stays local
Opening a saved recording reads it from IndexedDB in this browser — no network call.
Downloads are explicit
Download the WAV or save it to your local library when you choose to. Nothing else happens automatically.
Three steps to a clean clip
Load a file, mark the range you care about, and choose what to keep. No timeline software required.
- 1
Load your audio
Drop a file, choose one from disk, or open a take saved by the voice recorder.
- 2
Mark the range
Drag the handles or type exact start and end times — both stay perfectly in sync.
- 3
Keep or remove it
Keep the selection to trim down to it, or remove it to cut the middle and join the rest.
A few reasons people trim audio clips
Cutting dead air off the ends
Recordings often start with a few seconds of silence or shuffling before anyone speaks. Drag the start handle in, drag the end handle back, and keep the selection.
Lifting out a mistake or interruption
Select the cough, the doorbell, or the false start in the middle of a take and use "Remove selection" — the rest joins back together automatically.
Preparing a clip to transcribe
Trim a long recording down to just the part you need, then send the result into the free transcribe tool — still without an upload.
Getting a clip ready to combine
Trim two or three takes down to their best moments first, then stitch them together with the audio merger.
Split, merge, and transcribe too — all local
Need to cut a long file into multiple pieces instead of one range? Use the free audio splitter. Need to combine clips instead? Try the audio merger. Either way, the transcribe tool can turn the result into text — still no upload. Not sure how long a file already is? The duration calculator checks in an instant. Doing several of these at once — trim, split, and merge together? The Audio Studio puts the whole job on one timeline.
Audio trimmer FAQ
What audio formats can I trim?
Anything your browser can decode: WAV, MP3, M4A, AAC, FLAC, OGG, Opus, WebM, and the audio track of common video containers. If a file will not decode, you get a friendly error and can try another one.
Is my audio uploaded anywhere?
No. The file is decoded and edited with the Web Audio API right in this browser tab. Nothing is sent to a server, whether you drop in a file or open a take from your local library.
What is the difference between "Keep selection" and "Remove selection"?
"Keep selection" trims the clip down to just the highlighted range — everything outside it is discarded. "Remove selection" cuts the highlighted range out of the middle and joins what is left, so you can lift out a cough, a pause, or a mistake without losing the rest.
Can I type exact times instead of dragging?
Yes. The start and end fields accept M:SS.d (minutes, seconds, tenths) and stay in sync with the waveform handles in both directions — drag the handle or type a time, either updates the other.
Can I undo an edit?
Yes, undo steps back through your recent trims for the current file. Reload a fresh copy of the file if you want to start completely over.
What format does it export?
A standard 16-bit PCM WAV at your source file’s sample rate, ready to download or save straight to your local browser library.
