How do I split a video into parts for free?

Choose a video, pick either Equal parts or Every N seconds, then press Split video. The file is cut without re-encoding, so it finishes in seconds, and every part arrives in a single ZIP. Nothing is uploaded at any point.

Is splitting lossless?

Yes. The streams are copied rather than decoded and rebuilt, so every part contains the exact same encoded frames as the source. No quality is lost and no time is spent encoding — which is why a long recording splits in seconds instead of running at real time.

Why are the part lengths not exact?

Because lossless cutting can only begin at a keyframe. A part has to start with a complete frame, so each cut snaps to the nearest one, typically within a second or two of your target. Getting exact lengths would mean re-encoding, which would cost both quality and speed.

What are the two split modes for?

Equal parts divides the whole video into 2, 3, 4, 5, 6, 8 or 10 pieces of roughly the same length — useful for splitting a recording across several uploads. Every N seconds cuts fixed-length chunks instead, which is what you want when a platform caps clip duration.

How are the parts named?

Each part is named after your original file with a two-digit sequence number, so document.mp4 becomes document-part-01.mp4, document-part-02.mp4 and so on, all inside document-parts.zip. They stay in playback order, so sorting the folder by name gives the right sequence.

Why is the download a ZIP instead of separate files?

Because a browser cannot reliably trigger ten separate downloads without being blocked as a popup. The ZIP is stored rather than compressed, since video is already compressed and squeezing it again would waste time for no size saving — so extracting is instant.

Why did I only get one part?

Either the chunk length you set is longer than the video, or the file has very few keyframes so there was nowhere to cut. The tool reports this rather than handing you a pointless single-part ZIP. Convert the file to MP4 first if it has an unusual keyframe layout.

Which formats and sizes are supported?

MP4, MOV, WebM and MKV, up to 500MB. AVI is not accepted — convert it with the video converter first. Parts keep the original container, so splitting an MKV gives you MKV parts rather than forcing everything to MP4.

Split Video

Split a video into multiple clips online free — cut at timestamps or into equal-length segments. No sign-up needed — works entirely in your browser.

Split a video into equal parts or fixed-length chunks, losslessly — the streams are copied rather than re-encoded, so it takes seconds and costs no quality. Every part arrives in one ZIP. Runs entirely in your browser: no upload, no sign-up, no watermark, up to 500MB.

Two modes, two different jobs

Equal parts — divides the whole video into 2, 3, 4, 5, 6, 8 or 10 pieces of roughly equal length. Right when you need to get one recording out across several uploads and do not care about exact durations.
Every N seconds — cuts fixed-length chunks from 2 seconds upward. Right when something external sets the limit: a platform's maximum clip length, or a chunk size you know will fit a size cap.

Equal parts needs to read the video's duration first, so a file with a damaged or missing duration header will be reported rather than silently mis-split. Fixed chunks do not need it.

Lossless means keyframes, which means approximate lengths

This is the one thing to understand about lossless cutting, and it is a genuine trade rather than a bug. Video is stored as occasional complete frames — keyframes — with everything between them described as differences from the last complete one. A part has to begin with a complete frame, or there is nothing for the following frames to be different from.

So each cut snaps to the nearest keyframe, and part lengths land within a second or two of target rather than exactly on it. The alternative is decoding and rebuilding every frame so cuts can fall anywhere, which costs a generation of quality and turns a seconds-long job into a real-time one. For splitting a recording into shareable pieces, snapping is obviously the right call.

If you need a cut on an exact frame — ending on a specific word, or starting on a beat — that is a different operation. Trim video has a Precise mode that re-encodes to land exactly where you ask.

What you get back

Output of a split.
Property	Result
Quality	Identical to source — streams copied, never re-encoded
Speed	Seconds, not real time
Part lengths	Approximate, snapped to keyframes
Container	Same as your input — MKV stays MKV
Naming	`name-part-01.mp4`, `name-part-02.mp4`…
Delivery	One ZIP, stored not compressed, so it extracts instantly
Preview	None — the result is an archive, not a single clip

The zero-padded numbering is deliberate: part-01 through part-10 sort correctly in any file manager, whereas part-1 and part-10 would not.

When splitting is the right answer

Almost always because something else imposes a limit:

Messaging and email size caps. WhatsApp, Telegram and mail providers all cap attachments well below the size of a long phone recording.
Platform clip limits. Story and short-form formats cap duration, so a long take has to become several timed chunks.
Reviewing a long recording. Splitting a two-hour capture into ten pieces makes it navigable without a video editor.
Uploading over a poor connection. Several small files that can be retried individually beat one large upload that fails at 90%.

Worth checking first: if the aim is fitting a size limit, splitting is not the only option. The video compressor or resize video may get the whole thing under the cap in one file, which is usually nicer for whoever receives it.
