Use mm:ss (or hh:mm:ss for longer videos), or plain seconds.
Runs on a real video engine loaded into your browser (FFmpeg, compiled to WebAssembly) — about 30MB, downloaded once and cached for the rest of this visit. Nothing is uploaded; trimming happens on your device. This copies the video stream rather than re-encoding it, so it's fast and lossless — the tradeoff is the actual cut point can shift slightly to the nearest keyframe, usually well under a second.
How it works
- Upload your video.
- Drag the start and end handles to the part you want to keep.
- Export the trimmed clip — no re-encoding, so it's fast.
Frequently asked questions
Does trimming lose quality?
No, this trims without re-encoding, so quality is preserved exactly.
How precise can the trim be?
You can fine-tune the start and end points closely.
Will this work on large video files?
Yes, though very large files depend on your device's memory and processing power.
Your files are never uploaded. Gotool.xyz runs entirely as JavaScript in your browser. Your files are processed in memory and never touch a server — nothing to breach, nothing to clean up. Close the tab and it's like it never happened. The only thing we count is which tool ran (just the name, e.g. "merge") so we know what people find useful — never your file, its name, its size, or anything in it.
