Four ways to split a video
| Mode | What you set | Good for |
|---|---|---|
| Equal parts | Number of parts | Cutting a long lesson or game recording into episodes |
| Every N seconds | Part length | Stories (15 s), short clips for social media, fixed-length samples |
| By file size | Max size per part | Upload and email limits |
| My split points | Points you place yourself | Splitting at scene changes, songs or topics |
For your own points, move the playhead and press S or the Split button. Each split point appears on the film strip in yellow and can be dragged. If one part is not needed, for example a pause between two songs, remove it and it will be left out of the export.
Splitting to fit an upload limit
Many apps refuse files above a certain size. WhatsApp allows about 16 MB per video, the free plan of Discord about 10 MB, and most email services about 25 MB per message. Choose By file size, pick 8, 16, 25, 50 or 100 MB or type your own value, and the tool calculates where to split so that every part stays under the limit. The list shows an estimated size for each part before you export.
If you would rather keep one file and make it smaller, the compress video tool can aim for a target size instead. Often the best result is a mix: compress a little, then split into fewer parts.
Fast split without quality loss
With Fast split (no re-encoding) switched on, every part is copied straight from the original. This is very quick, even for a two-hour recording, and the picture is exactly as good as before. The limit is that each split point moves to the nearest key frame, so parts can differ from your settings by a second or two. When the points already sit on key frames, the tool tells you that every part is copied losslessly.
Fast split works when the output has the same format as the source, the quality is "Same as source" and the resolution is unchanged. If you choose a different format, such as GIF, or a smaller resolution, all parts are re-encoded. That takes longer but lets you convert and split in one step.
File names and download
The parts are named after the original file with a number: holiday-part01.mp4, holiday-part02.mp4 and so on. The numbers have two digits, so the files stay in the right order when sorted by name on Windows, macOS, Android and in cloud folders. Download the parts one by one, or press Download all to get a single ZIP.
Each part is a complete video of its own. It has its own start, plays in any player and can be uploaded or sent without the other parts. Nothing is lost between two parts: the last frame of one part is followed by the first frame of the next.
When you split a video here, the whole job is done inside your browser, so a large file does not need to be uploaded first, and the parts are ready as soon as the processing ends. To join parts back together later, or to combine them with other clips, use merge video. To pick just one short piece, trim video is simpler.
