Audio Trimmer
Cut any audio to the perfect length — set the start and end, preview, download. All in your browser.
No installs, no upload, 100% free.
Trim audio in three steps
A free audio cutter that runs entirely in your browser. Drop a file, mark the cut, download the piece you keep.
- Step 1
Upload your file
Drag an audio file into the upload area — or a video, and its audio track gets trimmed. MP3, WAV, M4A, FLAC, OGG and more all work.
- Step 2
Mark start and end
Drag the sliders or type exact times down to a tenth of a second, then hit Preview selection to hear exactly what you're keeping.
- Step 3
Trim and download
Pick the output format — MP3, M4A, FLAC, or WAV — and hit Trim. The cut is sample-accurate and happens on your device; nothing is uploaded.
What people cut
Most recordings are one good part surrounded by dead air.
Ringtones & alerts
Cut the hook out of a song — most phones want under 30 seconds, and the sliders get you there exactly.
Dead air & noise
Chop the fumbling at the start and the chair scrape at the end of a recording in seconds.
Podcast clips
Pull a quotable minute out of an hour-long episode for social posts and show notes.
Meeting highlights
Keep the decision, drop the small talk — trim a long call down to the two minutes that matter.
Sample-accurate cuts
The trim re-encodes rather than snapping to frame boundaries, so the cut lands exactly where you set it.
Need the words?
Trim the moment, then let SlayScribe transcribe it — or transcribe the whole file and read instead of scrubbing.
Why trim in the browser
A trim is a read, a cut, and a re-encode — your device does all three without breaking a sweat. The file never leaves your machine, there's no queue and no upload time, and the preview plays the actual selection before you commit to the cut.
Frequently asked questions
Is the audio trimmer free to use?
Yes — the audio trimmer needs no account, adds no watermarks, and caps nothing. Every cut runs in your browser.
Which formats can I trim?
Any common audio format — MP3, WAV, M4A, AAC, FLAC, OGG — and video files too (the audio track is trimmed). Output: MP3, M4A, FLAC, or WAV.
How precise is the cut?
To a tenth of a second in the UI, and the cut itself is sample-accurate — the audio is decoded and re-encoded, not snapped to frame boundaries.
Does trimming lose quality?
One re-encode at 192 kbps for MP3/M4A — transparent for speech and most music. Pick FLAC or WAV output for a lossless cut.
Does my audio get uploaded?
No. Decoding, cutting, and encoding happen locally on your device.
Can I cut several pieces from one file?
Run the trimmer as many times as you need — trim, download, adjust the sliders, trim again. To glue pieces together afterwards, use the Audio Joiner.
Need the words, not just the audio?
SlayScribe turns any audio or video into accurate text in seconds — transcripts, captions, and subtitles in 99 languages.
