Frequently Asked Questions
Will trimming affect video quality?
No. This tool uses stream copy (-c copy) which cuts the video without re-encoding, so there is zero quality loss.
How precise is the trim?
Trimming is accurate to 0.1 seconds. For frame-perfect cuts, the keyframe alignment may vary slightly.
What formats can I trim?
Upload MP4, MOV, AVI, WebM, or MKV. Output is always MP4 for maximum compatibility.
Is there a maximum video length?
No. You can trim videos of any length — the limiting factor is your device's available RAM.
Is my file uploaded anywhere?
No. Everything runs locally in your browser using FFmpeg.wasm. Your file is never sent to any server.
