The video file stays on your device — BibiGPT never receives any video data. **Are there watermarks or signup requirements?** No watermarks and no signup. The exported clip is identical in quality to what desktop editing software would produce, and is safe for commercial use. **Which formats are supported?** Input: MP4, WebM, MOV, AVI, and other popular formats. Output: MP4 or WebM. For H.264-encoded inputs, the tool uses stream copy mode when possible for near-lossless cuts. **Will large files lag?** Videos under 500 MB usually finish in under 30 seconds on a typical laptop. Files over 1 GB depend on CPU and memory — test with a short segment first if unsure. **How precise is the trim?** Down to one second. For sub-keyframe precision, the tool re-encodes the cut points to maintain accuracy. **Does it work on mobile?** Yes — works in Chrome / Safari on phones and tablets, though desktop is fastest. *** **Related Feature**: [Free Video to GIF Converter](https://bibigpt.co/features/free-online-video-to-gif-converter) — Try it now **Upgrade to Pro**: Unlock unlimited usage → [View Pricing](https://bibigpt.co/pricing) ## Related Features
