A long recording is easier to share, post and edit in pieces. Choose how to divide it — by length, by number of parts or at your own markers — and download every part separately or together as a ZIP. Nothing is uploaded.

Overview
Splitting turns one video into several consecutive files that together cover the whole thing. There are three ways to place the cuts. Every N seconds makes parts of a fixed length (60 seconds by default), with the last part holding whatever is left over. Equal parts divides the video into a number of pieces of the same length and shows how long each will be. Markers lets you play the video, pause where you want a cut and press Add marker, or the M key, so you can split at scene changes or topic breaks. The cut points appear as lines on a thumbnail timeline, and a list shows the start, end and length of every part before you run anything.
Fast mode copies the compressed video and audio without re-encoding, so the whole job is a single pass that finishes in seconds and loses no quality. Compressed video can only start cleanly on a keyframe, so the splitter first scans the file for keyframes and moves each cut to the nearest one, then tells you where the cuts actually landed. Phone footage usually has a keyframe every one or two seconds, so parts end up close to what you asked for. Screen recordings and some streaming exports have very few keyframes, and in that case two requested cuts can collapse into one and you get fewer parts.
Precise mode re-encodes each part separately so every cut lands on the exact frame. It keeps the original container: MP4, MOV and MKV parts use H.264 video at CRF 20 with AAC audio, and WebM parts use VP8 with Opus. Because every part is encoded, it takes roughly as long as converting the whole video, which in a browser can mean several minutes for a long 1080p file.
The work is done by FFmpeg 5.1 compiled to WebAssembly. The first split downloads the engine (about 31 MB), which your browser then caches, so later jobs start straight away. The source file is read from disk on demand rather than copied into memory. Up to 100 parts can be made in one go, and they are named in order (yourvideo-part-01, part-02 and so on) so they sort correctly in any folder.
| Method | Best for | Example |
|---|---|---|
| Every N seconds | Platform length caps | 60 s parts for Stories |
| Equal parts | File size limits | A 900 MB file into 4 parts |
| Markers | Scenes and topics | Chapters of a lecture |
Drop a video into the splitter or click to choose one.
Pick Every N sec, Equal parts or Markers, and set the length, the number of parts or your markers.
Check the cut lines on the timeline and the list of parts.
Choose Fast (lossless, nearest keyframe) or Precise (exact frame, re-encoded).
Click Split, then download each part or all of them as a ZIP.
Use cases
Break a long clip into 15, 30 or 60 second pieces for platforms that cap the length of a single post, and upload them in order.
Drop markers at each topic change in a two-hour recording, then share only the sections people need instead of one enormous file.
Divide a large file into equal parts so each one fits through an email, chat or upload limit, without recompressing and losing quality.
Split raw footage at scene changes so every shot becomes its own file, which makes sorting and importing into an editor much quicker.
Pro tips
Answers to common questions about the video splitter.
In Fast mode each cut moves to the nearest keyframe, because that is the only place a stream-copied video can start cleanly. The result screen lists the actual cut times. Use Precise mode if you need cuts on exact frames.
Some videos, especially screen recordings, have keyframes many seconds apart. When two requested cuts snap to the same keyframe they merge into one. Precise mode re-encodes, so it always produces the number of parts you set.
Fast-mode parts are bit-for-bit copies of the original streams, so there is no quality loss. Precise-mode parts are re-encoded at a high quality setting (H.264 CRF 20 for MP4, MOV and MKV), which looks the same as the source for most footage.
Up to 100 per job, and each part must be at least a quarter of a second long. If your settings would produce more, the splitter asks you to use longer parts.
The same container as your video. An MP4 produces MP4 parts, a MOV produces MOV parts, and so on. In Fast mode the codecs are untouched; in Precise mode WebM parts use VP8 and Opus, and the others use H.264 and AAC.
