Everything you need to know about Video Trimmer & Splitter and local WebAssembly processing.
How to trim a video online for free?
Upload your video to VideoReduce.com's Video Trimmer, drag the start and end handles on the timeline to select the part you want, and click Trim. The lossless stream-copy engine exports your cut in under a second with zero quality loss.
How fast is lossless stream-copy trimming?
Stream-copy trimming completes in under a second — even for large 1GB+ files — because it copies raw video packets without re-encoding any frames. Your video quality remains 100% identical to the original.
Can I trim videos on iPhone or Android?
Yes! Open VideoReduce.com in Safari (iPhone) or Chrome (Android), upload your video from Photos/Gallery, and trim it directly in your mobile browser without installing any app.
Can I split a video into multiple clips?
You can trim one segment at a time. To create multiple clips, simply repeat the process with different start and end points for each segment you need.
Does trimming reduce video quality?
No! Our lossless stream-copy mode copies the video and audio streams bit-for-bit without any re-encoding, so there is absolutely zero quality degradation.
