Frequently Asked Questions
No — this tool uses -c copy in FFmpeg, which performs a stream copy rather than re-encoding. This is extremely fast and preserves the original quality exactly. The only trade-off is that the cut point snaps to the nearest keyframe, which may be within a second of your requested time.
There is no enforced length limit — the tool runs entirely in your browser using WebAssembly. The practical limit depends on your device's available RAM. Files under 500 MB work well on most modern computers; very large files (1 GB+) may be slow or cause memory pressure.
Each trim operation produces one continuous clip. To extract multiple segments, click "Trim Again" after each download, adjust the start and end times, and trim again. The original video stays loaded between operations.
Yes. Because the video and audio streams are copied without re-encoding, the bitrate, resolution, codec, and visual quality of the output are identical to the original. No generation loss occurs.
Absolutely not. The entire process runs in your browser using FFmpeg compiled to WebAssembly. Your video data never leaves your device, so it is completely private — no account, no upload, no cloud storage.
