Split a video
Cut one video into parts and save them in one zip, without uploading the video anywhere.
- Nothing is uploaded
- Works offline after first visit
- Open source
- No watermark. The limit is your device’s memory (phones hold less): a long or large video may need a computer.
Split a video into parts in your browser: at times you type, every few seconds or into equal parts. It is free, needs no account and adds no watermark, and your files are not uploaded: everything runs in your browser on your device. No watermark. The limit is your device’s memory (phones hold less): a long or large video may need a computer.

Cut one video into parts when a file is too long to send, too big for an upload limit, or holds several things that belong apart: a recording of three lectures, a match with its breaks, a screen capture you want in chapters. Drop the video, say where the parts begin and press Split video.
There are three ways to say it. Type the times where each new part starts (1:30, 4:00). Give a length and the video is cut every 30 seconds or every 5 minutes, with whatever is left as the last part. Or pick a number of equal parts, up to 50. The page lists every part and the total size before it starts.
By default the video is copied, not re-encoded, so a long video splits in seconds and every part looks like the original; the price is that a part can begin a moment before the time you gave, at the key frame. Tick Exact cuts and each part starts on the frame, at the cost of re-encoding. To keep one stretch only, use Cut video or Trim MP4; to join parts again, use Combine videos.
Want two videos on one screen? Use Side by side video.
How it works
- Drop the video, or tap to pick it.
- Type the times, a length, or a number of equal parts, and check the list of parts.
- Press Split video, and download the parts as one zip.
In your browser, not on a server
Mediabunny (MPL-2.0) reads the MP4, MOV, WebM or MKV container in your tab to find its length, and the parts are planned in seconds so that each one ends where the next begins. Each part is then cut on its own: the video and sound packets between its two points are copied into a new file of the same type, starting from the nearest key frame, or, with exact cuts, decoded and re-encoded by your browser’s own video encoder (WebCodecs). The parts are packed into a zip by code in the page.
Compared with upload-based tools: Online video splitters upload the whole file, cap free videos at a few hundred megabytes and often add a watermark. Here nothing is uploaded, and a long video splits in seconds because the video is copied rather than re-encoded.
Verify it yourself. Give the page a short while after one visit to save itself for offline use, then turn off Wi-Fi or switch to airplane mode and run the tool again. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.
Questions
Does it make one file or several?
Several: one file per part, named like clip-part-01.mp4, and Download all gives you them as one zip.
Can I split a video every 30 seconds?
Yes. Choose Every so often, type 30 and keep the unit on seconds. A 95-second video gives four parts: 30, 30, 30 and 5 seconds.
Is it the same as cutting out one clip?
No. This page cuts the whole video into parts end to end. To keep one stretch only, use Cut video or Trim MP4.
Is the file uploaded anywhere?
No. There is no server in this process. The page is a static file and the work is done by code running inside your browser tab. Give the page a short while after one visit to save itself for offline use; then you can turn off Wi-Fi and it still works.

Cut one video into parts at the times you choose, every so often or into equal pieces, and save them in one zip. Done on this device, and the video is not uploaded.
Webcam test
Check that your webcam works before a Zoom, Teams or interview call: see the live picture, the real resolution and the measured frame rate. Nothing is uploaded.
Speaker test
Check that both sides of your speakers or headphones play: send a tone to the left, the right or both, sweep up through the pitches, or play pink noise. It starts quiet, and nothing is uploaded.
Keyboard test
A free key tester: press any key and it lights up on an on-screen keyboard, in an ANSI or ISO layout, and stays marked so you can see which keys you have not tried yet. What you type stays in this tab.
