Cut a song to the chorus, top and tail a podcast, or lift a clip out of a video. It all happens in this tab — your file never touches a server.
MP3, WAV, M4A, OGG, FLAC, or the audio track of a video file.
There's no server to upload to. Decoding and encoding run on your machine, so the audio never leaves it — you can even go offline once the page loads.
No queue, no sign-up, no watermark, no size cap. The waveform draws and you're editing — nothing between you and the cut.
Zoom to individual samples and cut exactly where you mean to. Add an equal-power fade, then export MP3 or lossless WAV.
From file to finished cut in under a minute.
Drag in an MP3, WAV, M4A, OGG, or FLAC — or a video, and it takes the audio track. It's read straight off your disk.
Drag across the waveform, then nudge the handles until it's exact. Zoom in to work at the millisecond level.
Keep the selection or delete it, add a fade, pick MP3 or WAV. Encoding happens on your machine, then the file downloads.
No. There is no server to upload to. The page decodes, edits, and re-encodes your file using APIs built into your browser, so the audio never leaves your computer. You can disconnect from the internet after the page loads and everything still works.
Only the memory your browser will hand out. Decoded audio takes about 10 MB per minute of stereo, so a full album in one file may struggle on a phone. A typical song is nothing.
MP3 stores audio in frames of 1,152 samples, so the encoder rounds up to the next whole frame — about 26 milliseconds at 44.1 kHz. Export WAV if you need a sample-exact cut.
Not yet — iOS wants an .m4r file, which needs an AAC encoder this build doesn't ship. You can export MP3 and convert it, or trim to under 40 seconds and use it as an Android ringtone directly.
Whatever your browser can play, which in practice means MP3, WAV, M4A/AAC, and FLAC everywhere. OGG and Opus work in Chrome and Firefox but are unreliable in Safari.
Free, no account, nothing uploaded. Drop a file and start editing.
