Split a Video into Parts
100% private — runs on your device, never uploaded. Works offline once loaded.
Some limits are not about file size but length: WhatsApp status wants 30 seconds, Instagram stories 60, and plenty of upload forms and messaging apps cap the minutes rather than the megabytes. Splitting is also how a long recording becomes chapters or a lecture becomes parts people will actually finish. Choose a length for each part or a number of equal parts, and every piece comes back in one ZIP. The fast setting copies the video without re-encoding, so a two-hour recording splits in seconds with no loss of quality at all.
Why the parts are not exactly equal
Video is stored as occasional complete frames — keyframes — with everything between them described as changes from the frame before. A part can only begin at a keyframe, because there is nothing to start from otherwise. On the fast setting the file is copied rather than re-encoded, so each cut lands on the nearest keyframe: typically within a few seconds of where you asked, at no cost in quality and in a fraction of the time.
When the cut has to be exact, the exact setting re-encodes and places keyframes precisely where the parts should begin. It takes much longer and costs one generation of quality. If a video has very few keyframes — short clips and screen recordings often have just one — the fast setting cannot split it at all, so it re-encodes automatically rather than handing back a single "part".
What people split video for
- Platform length caps: 30 seconds for a WhatsApp status, 60 for an Instagram story, 15 for some ad formats
- Breaking a lecture, sermon or conference talk into chapters people will finish
- Getting a large file past an upload limit that caps minutes rather than megabytes
- Splitting a long recording so several people can edit or review different parts
Frequently asked questions
Do the parts play on their own?
Yes — each is a complete MP4 with its own timestamps reset to zero, so every part plays and seeks normally.
Can I split at specific moments instead?
Not in one pass here. Use the Trim tool to take out each section you want, or the Video Studio timeline for anything more complex.
