Split Video OnlineCut a long video into ready-to-post parts.

Yes. Split as many videos into as many parts as you like, with no account and no watermark on the parts.

No. The video is read and cut in your browser, and the parts are saved in your browser’s own storage until you download them. Nothing is sent to a server, so private recordings stay on your device.

Lossless parts are copied from your file without re-encoding, so they keep the original quality and are ready in seconds. A copied part can only begin on a key frame (a full picture the video stores every few seconds), so each cut moves to the nearest key frame and the list shows the real start, end and length of every part. Choose Exact cuts to cut at the exact moment; the parts are then re-encoded, which takes longer.

Choose Max file size and pick or type the limit. Parts are planned to stay a few percent under it, and in Lossless mode from the bytes actually stored in your file, so each part is sized from its own content. A megabyte here is 1,000,000 bytes, slightly less than the binary megabyte some sites count in, so the parts fit either way. Check the limit on the site you post to; they change.

You can open MP4, MOV, M4V, WebM and MKV videos. Lossless parts keep the original video stream: H.264, HEVC or AV1 video comes out as MP4, VP8 or VP9 as WebM. Exact cuts are re-encoded to MP4 (H.264 with AAC sound), which plays almost everywhere. Every part keeps its sound, and the parts follow on from each other without a gap or an overlap.

Lossless splitting takes seconds even for long videos because nothing is re-encoded. Exact cuts take about as long as compressing the video, depending on your device. Files up to 4 GB work; the parts are written to your browser’s storage instead of memory, so you need free disk space about the size of the video.
