Audio cutter
See your audio as a waveform, mark a selection with two handles, and keep it, remove it, or join several. You can also split it into equal parts, at regular intervals, or at points you choose. Add fades, change the volume, and save as MP3, WAV, OGG, or M4A.

Your browser doesn’t include audio WebCodecs, so its own decoder is used. It works the same with MP3, WAV, M4A, and FLAC; very long audio may take longer, and OGG isn’t available.

What do you want to do?
No segments yet. Choose one with the handles and select “Add the selection.” They are joined in the order they appear in the audio.

Select the waveform or play up to the point where you want to split.
No marks yet. Select “Split here” to create one at the cursor, or double-click the waveform. Drag a mark to move it; with the keyboard, the arrow keys move it 0.1 s (1 s with Shift) and Delete removes it.

How to use it
- Drop your audio into the box or select it from your device. A video works too: the tool uses its audio.
- Move the handles on the waveform, or type the times, to mark the selection. Listen with the play button and turn on looping if you want to fine-tune it.
- Choose whether to keep the selection, remove it, or join several segments. If you need to, add a fade in and a fade out, change the volume, or normalize it.
- To split the audio, switch to “Split” and choose equal parts, regular intervals, or points you mark on the waveform. Check the preview with the start, end, and length of each part.
- Choose the format and select “Cut audio” or, in Split mode, “Split and download all (ZIP).” Listen to or download the result and, if you like, save each part separately.
Frequently asked questions
Is my audio uploaded to a server?
No. The audio is opened and cut inside your browser, on your own device. Nothing is sent over the internet, so you can edit private recordings safely.
Can I split an audio file into several parts?
Yes. Switch the mode to “Split” and choose how to divide it: into equal parts (2 to 50), at regular intervals (for example every 30 seconds or every 1:30), or at points you mark on the waveform. The preview shows the start, end, and length of each part, and the “Split and download all (ZIP)” button saves them together in one compressed file. You can also download each part separately.
How do I cut a song to make a ringtone?
Load the song, listen, and find the part you like with the handles, then use the 15, 30, or 40 second buttons to set the length. Add a fade in and a fade out so it doesn’t cut off abruptly. For iPhone choose the M4R format; for Android, MP3 or M4A.
Can I remove a piece from the middle and join the rest?
Yes. Choose “Remove the selection,” mark what you don’t want, and the rest is joined automatically. With “Join several segments” you can save separate pieces and combine them into one file, in the order they appear in the audio.
Is quality lost when cutting or splitting, and which formats are supported?
If you save in the same format as the original and don’t use fades, volume changes, or normalization, each section is copied without re-encoding: nothing is lost and the cut snaps to the nearest 25 milliseconds. Otherwise the audio is encoded again: with WAV or FLAC there is no loss, and with MP3 at 192 kbps or higher the difference is hardly noticeable. You can load MP3, WAV, OGG, Opus, M4A, AAC, FLAC, and WebM files, or a video; a file can be up to 2 GB, and the real limit is your device’s memory.
How do I make the cut more precise?
Zoom into the waveform with the zoom buttons or with Ctrl and the mouse wheel. With the keyboard, the arrow keys move a handle in steps of 10 milliseconds, or 100 milliseconds with Shift. In Split mode, the arrow keys move each mark by 0.1 seconds, or 1 second with Shift. You can also type the exact time in the start and end fields.
Split audio into parts
Besides trimming, you can break an audio file into several files. Choose equal parts to divide it into a fixed number of pieces, regular intervals to cut every 30 seconds, every minute and a half, or whatever you need, or mark your own points on the waveform. The preview list shows the name, start, end, and length of each part, and the split points are drawn on the waveform. The result downloads as a ZIP with file names numbered with leading zeros, and each part can also be downloaded on its own.
Three ways to cut
- Keep the selection: you keep only what is between the two handles. This is the usual choice for trimming the start and end.
- Remove the selection: deletes a section from the middle, such as a cough or a long pause, and joins what is left.
- Join several segments: add as many pieces as you want to a list and they are combined into a single file.
Settings that improve the result
- Fades: the sound fades in and out smoothly, with no abrupt cuts. They are useful for ringtones.
- Normalize: brings the loudest point close to the maximum without distorting. If you would rather control it yourself, use the volume.
- Silence at the ends: one button detects where the sound starts and ends and adjusts the selection.
Keyboard shortcuts
Space plays and pauses, I and O mark the start and end at the current position, and L turns on looping. In Split mode, the arrow keys move the focused mark and Delete removes it.
About the encoders
MP3 files are created with an encoder based on LAME, compiled to WebAssembly (LGPL license). If your browser can’t create M4A (AAC), the AAC encoder from FFmpeg is used, also in WebAssembly (LGPL license), and FLAC files are created with libFLAC (BSD license). Each one is downloaded only when you choose that format and runs on your device.
