Split Video
Cut one video into several files. Click the timeline to move the playhead, press Split here, and drag the green lines to place each cut exactly where you want it. Nothing is uploaded.
How to split a video into parts
- Drop in a video. It is read locally — nothing uploads, and there is no engine to download first.
- Click the timeline to move the playhead, then press Split here. Drag a green line to move that cut, or select it and use the arrow keys for the last tenth of a second. The equal parts buttons place them all at once, and Clear cuts resets the lot.
- Check the part list. Each row shows the range, the length and an estimated file size, so you can see whether every part clears the cap you are aiming at before you spend any time on it.
- Press Snap to keyframes if you want the split to be an instant, lossless copy — it moves each cut to the nearest point the file can be cut at without re-encoding, and tells you how far first.
- Split, then download the parts one at a time or all at once. They only exist in this tab, so save them before you leave.
Frequently asked questions
Is my video uploaded to a server?
No. The file is read straight from your device, every part is cut and written inside your browser, and the downloads come out of this tab's own memory. Nothing is uploaded, there is no account, and no copy of your video leaves the machine.
What does Snap to keyframes do?
It moves every split point onto the nearest keyframe, which lets the parts be copied straight out of the original instead of rebuilt. Compressed video only holds complete pictures at keyframes — every frame in between is stored as a change from the one before — so a part can only begin at one without decoding the clip first. Snapping is instant, lossless and usually moves each cut by under a second; the tool tells you the furthest any cut would move before you press it. If the cut matters more than the speed, leave it where it is and the parts are re-encoded instead.
Why is my split re-encoding instead of copying?
Because at least one cut isn't sitting on a keyframe. That is the normal case when you place cuts by hand or use the equal-parts buttons, and it is the price of a cut landing exactly where you put it. Press Snap to keyframes to trade a little precision for an instant, lossless copy. The other reason is a file whose codecs no container can carry portably, which is rare — the tool says so, and snapping won't help there.
How precisely can I place a cut?
Click anywhere on the timeline to move the playhead, then press Split here. Drag a green line to move that cut, or select it and use the arrow keys — a tenth of a second per press, a full second with Shift held. The player follows the line as you drag, so you can see the frame you are cutting on.
Do the parts lose quality?
Only if they are re-encoded. Snap the cuts to keyframes and nothing is decoded at all: each part contains the source's own compressed frames, bit for bit. Left off the keyframes, every part is decoded and re-encoded, which costs one generation of quality — the tool always says which of the two it is about to do.
Do the parts join back up with no gap?
Yes. Each part ends exactly where the next one begins, so nothing is lost or duplicated at a seam. You can feed the parts straight into the Merge Videos tool and get the original back — and because they all carry the same format, that merge is a stream copy too.
Why is there no ZIP download?
Adding a ZIP library for one feature is a real cost paid by every visitor to the site, and a ZIP of already-compressed video saves almost nothing. Each part downloads on its own instead. Your browser may ask once to allow multiple downloads from this page — allowing it lets the rest through.
How many parts can I make at once?
Up to 20. Every part is held in this tab's memory until you have downloaded it, and past that point the list stops being something you can scan. Each part also has to be at least 1 second long.
How is this different from the Video Trimmer?
The trimmer keeps one range and throws the rest away. This keeps everything, as several files. If you want to cut a single clip out of a longer recording, use the trimmer; if you want the whole recording in pieces — to clear an upload size cap, or to post a long video as a thread — split it here.
My video is too long to compress under 10MB. Does this help?
Yes, and it is the main reason this tool exists. Below a certain bitrate a compressor cannot make a long clip small without destroying it, so the compressor tells you to try a shorter clip. Splitting is how you do that without throwing anything away: each part is a fraction of the running time and a matching fraction of the file size, and the tool estimates each part's size before you run it.
