Video Splitter – Free Online Tool
Split video into multiple parts. Divide long videos into shorter segments easily.
Example Output
Split modes: every N minutes/seconds, by file size, at exact timestamps, or by N equal segments. Stream-copy when possible (instant).
9 MP4 files — each ~10 min, named webinar-part-01.mp4 … part-09.mp4
What is Video Splitter?
Split a long video into smaller files — by time interval, by target file size, at exact timestamps, or into N equal segments. Stream-copy when the split lands on a keyframe (instant, lossless); otherwise frame-accurate re-encoding at the boundary.
Why use this tool?
- Instant results — no waiting on a server or upload progress bar
- Touch-friendly UI, fine on phones for on-the-go edits
- No registration, account, or installation required
- No video upload — clips of any length stay on your local machine
- FFmpeg WASM means the same encoder that powers desktop tools, running in your browser
How to use
- Upload your video file
- Set split points (timestamps)
- Click "Split Video"
- Download video parts as ZIP
Examples
Upload-limit split
A 4 GB webinar splits into 4 × 1 GB chunks that fit any upload limit, then merge again on the other end.
Course-module split
A 90-minute course splits at exact chapter timestamps (00:15:00, 00:35:00, 01:05:00) into module files.
Equal segments for distribution
A 60-min interview splits into 6 × 10-min parts for distribution on a platform that caps individual videos at 10 minutes.
Common use cases
- Splitting long videos to fit upload limits
- Breaking a course / webinar into modules
- Producing short segments for social media
- Distributing parts for parallel transcription
- Reducing per-file size for email sharing
Troubleshooting
- Each split file is slightly different in size despite "equal segments"
- Splits snap to keyframes. Enable "frame-accurate" mode for exact equal segments (re-encodes boundaries).
- Audio glitch at split boundaries
- Audio frames don't align with video keyframes. Frame-accurate mode re-encodes the boundary to fix the glitch — slower, but clean.
- Output files don't open in some players
- Switch container to MP4 with H.264. Stream-copy preserves whatever codec the source used; some players are picky.
