Cut Without Re-Encoding

Why Our Video Trimmer Stands Out: Lossless Cuts, Instant Results

Zero Quality Loss
Stream-copy trimming copies your original video and audio data directly instead of re-encoding it, so the trimmed clip looks and sounds exactly like the source.
Precise, Visual Editing
A filmstrip of real thumbnails runs across the timeline, so you can drag the start and end handles to the exact moment you want without guessing.
Nearly Instant Results
Skipping re-encoding means most trims finish in a couple of seconds, even on longer recordings, since Video Trimmer only has to copy the selected range.
Private by Design
Every step of the trim runs locally through WebAssembly. Your footage is never uploaded, and no account is ever required.
