How to Split a Video Online
Splitting a video online should take seconds, not an afternoon of learning a desktop editor. This browser video splitter keeps the workflow down to four steps. First, select a video from your device — MP4, MOV, M4V and WebM files all load directly, and nothing is uploaded anywhere. The editor appears immediately with your clip in the preview window and a single timeline part covering the whole video.
Second, move the playhead. You can click anywhere on the timeline, drag the playhead marker, or use the arrow keys for small nudges and Shift with the arrow keys for one-second jumps. The current position is shown down to the millisecond so you can find the exact frame where a sentence ends or an action begins.
Third, press Split (or the keyboard shortcut S). The part under the playhead becomes two parts that share the cut point exactly: no duplicated frames, no missing interval and no overlap. Fourth, repeat. Split as many times as your edit needs — three cuts produce four parts, and each one can be selected, trimmed, moved, deleted or downloaded on its own.
Because splitting only records an instruction rather than writing a new file, the timeline responds instantly even on a long clip. Your original video is never modified on disk.
How to Remove a Part From the Middle of a Video
Cutting something out of the middle — a stumble, a long pause, a phone ringing, a repeated take — is the most common reason people reach for an online video cutter. The pattern is always the same. Move the playhead to the moment the unwanted section begins and split there. Then move the playhead to the moment it ends and split again. You now have three parts: the good beginning, the section you want gone, and the good ending.
Click the middle part to select it — the selected part is outlined and marked, not just tinted, so the selection stays obvious for everyone. Press Delete (or Backspace, or the Delete button in the toolbar). The middle part disappears from the edit and the two remaining parts move together.
There is no black gap where the deleted section used to be. A ten-second video with two seconds removed becomes an eight-second video, and the preview jumps straight from the end of the first part to the start of the last one. If you change your mind, Undo restores the deleted part exactly where it was.
How to Reconnect Split Video Parts
This editor uses ripple editing, which simply means later parts always shift left to close a gap. Whatever remains on the timeline is treated as one continuous edited video, and the edited clock at the top of the preview counts the joined duration rather than the original source duration.
The Reconnect Parts button makes that explicit. It confirms that every kept part sits directly against its neighbour in the current order, and it tells you when the parts are already connected so you never trigger pointless work. Reconnecting is a timeline operation: nothing is encoded and nothing is written until you export, so you can reorganise an edit dozens of times without waiting.
Split Videos for YouTube Shorts, TikTok and Reels
Short-form video rewards tight editing. A vertical clip recorded on a phone usually contains a few seconds of setup at the start, a mistake somewhere in the middle and a couple of dead seconds at the end. Splitting those away is often the only edit a Short needs.
Vertical footage keeps its original resolution and orientation here. A 1080 × 1920 recording is exported as 1080 × 1920 — no rotation, no stretching and no black side bars added to force a landscape frame. The editor also shows the final joined duration as you work, so you can see at a glance when your clip is comfortably short. Platform rules change over time, so check the current requirements of YouTube, TikTok or Instagram before publishing rather than trusting any fixed number baked into a tool.
Download Individual Video Clips
Sometimes you do not want one joined video at all — you want the pieces. Each part on the timeline has its own Download Clip action, which exports only that range as a standalone MP4 named after your original file, such as my-recording-part-02.mp4. Nothing else is processed, so a single short clip finishes quickly even when the rest of the video is long.
When you have two or more parts, Download All Parts exports them one after another and collects them into a video-parts.zip archive. Clips are encoded sequentially rather than all at once, which keeps browser memory under control on modest laptops and phones.
Join the Remaining Clips Into One Video
Export Final Video takes every kept part, in the order shown on the timeline, and renders one MP4. Deleted sections are absent, the parts follow each other without gaps and the audio is cut and rejoined with the picture so speech stays aligned with lips. Reordered parts are exported in their new order, so a clip arranged 3, 1, 2 on the timeline plays back as 3, 1, 2.
Output is H.264 video with AAC audio in an MP4 container, written with a fast-start flag so the file begins playing quickly when it is uploaded or streamed. There is no watermark of any kind.
Does Splitting Reduce Video Quality?
Splitting on the timeline does not alter your source data at all. Cuts, deletions, trims and reordering are stored as numbers describing which ranges to keep; the file you selected is read only.
The final export is different. Joining arbitrary ranges into one continuous file requires the video to be encoded again, and any re-encode of a compressed video introduces some loss. This tool keeps that loss small by using high-quality H.264 settings by default and by encoding once rather than repeatedly. The High Quality preset is close to visually lossless for most footage, Balanced is a good default, and Smaller File trades a little detail for a much smaller download. It would be dishonest to claim zero quality loss after a re-encode, so the presets simply let you choose where you sit on that trade-off.
Why Accurate Video Cuts May Require Re-Encoding
Compressed video does not store every frame in full. Instead it stores occasional complete frames, called keyframes, and describes the frames in between as differences from them. Keyframes typically appear once every one to several seconds.
A copy-only cut can therefore only begin at a keyframe. If you want a cut at 6.250 seconds and the nearest keyframe is at 5.000, a copy-only tool either shifts your cut by more than a second or leaves a frozen, glitchy start. To honour the exact point you chose, the frames after the keyframe have to be decoded and written again. That is why an accurate export encodes, and why exporting takes longer than splitting.
Private Browser-Based Video Editing
Most online video editors work by uploading your file to a server, processing it there and sending a result back. That means your footage — which may include your face, your voice, your home, your clients or unreleased work — sits on someone else's infrastructure.
This splitter takes the opposite approach. Preview uses your browser's own video playback, and the encoder is a WebAssembly build of FFmpeg that runs inside your tab. No file, frame or audio sample is transmitted. Only anonymous counters such as “an export started” are recorded, never a filename, duration, dimension or byte of media. Once you close the tab, everything is gone from memory.
Best Video Format for Shorts
MP4 with H.264 video and AAC audio remains the safest choice for short-form video. It plays on essentially every phone, browser, television and editing application, and every major social platform accepts it. That is why it is the default output here.
It is not a universal requirement, though. Platforms also accept MOV and WebM, and newer codecs such as HEVC or AV1 can produce smaller files at similar quality where support exists. If you are unsure, exporting MP4/H.264 at your original resolution is the option least likely to cause a rejected upload or an unplayable file.
