Cut and trim any song or recording with this free online audio cutter and MP3 trimmer. Drag on the waveform to select exactly the part you want, add fades, trim silence, and export a clean WAV — all in your browser, with nothing uploaded and no signup.
Audio Cutter & MP3 Trimmer
Cut and trim any audio file — drag on the waveform to select the part you want, add fades, then export a clean WAV. Everything runs in your browser; nothing is uploaded.
Drag anywhere on the waveform to select a region, or drag the purple edges to fine-tune the start and end. “Trim silence” snaps the selection to the first and last audio above the threshold. The export is a clean WAV of exactly your selection, with any fades applied.
How to cut audio online
- Upload your file — MP3, WAV, M4A, OGG or FLAC. It is decoded on your device and never uploaded.
- Select the part to keep — drag across the waveform, or drag the purple edges to fine-tune the start and end. Use the quick buttons (First 15s, Last 30s, Middle 30s) for common cuts.
- Add fades and trim silence — set a fade-in or fade-out so the cut doesn’t click, and tap “Trim silence” to snap the selection to the first and last audio.
- Preview and export — press play to hear just the selection, then Download WAV to save your cut.
What you can use it for
- MP3 cutter — cut a downloaded track to the verse, hook or section you need.
- Loop cutter — set clean loop points before dropping a clip into a beat or sampler.
- Ringtones — trim a short segment for a ringtone or notification sound.
- Social clips — export a section for TikTok, Reels, Shorts or a preview post.
- Fade editor — add smooth fades to rough edits so they don’t pop at the edges.
Why a waveform beats guessing
Most online cutters only give you numeric start and end boxes. This one draws the actual waveform, so you can see the intro, the drop and the silence — and drag a precise selection instead of guessing timestamps.
Free and private
Everything runs locally with the Web Audio API. Your file never leaves your browser, there’s no signup, and the WAV export has no watermark. Need to slow the clip down or add reverb after cutting? Send it to the Slowed + Reverb Generator, or shape its tone with the Online Equalizer.
