Trim Video
Runs in your browser — your files are never uploaded.
Cut a video down to the part you actually want. There is a genuine choice here that most tools hide: a fast cut copies the existing streams untouched and finishes almost instantly, but it can only land on a keyframe, so the clip may begin a second or two early. A precise cut re-encodes to the exact frame and takes real time. Both run entirely on your device, and neither adds a watermark.
OptionsPrecision: Exact — re-encodes, slower

Frequently asked questions
Why does my fast cut start a bit early, or on a frozen frame?+
Because it cuts on a keyframe. A fast cut copies the compressed video stream as-is, and a video can only be cut where a full frame is stored — every few seconds. Cutting between keyframes leaves the first fraction of a second without the reference it needs, which shows as a grey or frozen opening. Choose Exact to cut on the precise frame.
Which precision should I use?+
Exact for anything short or where the timing matters. Fast when you are pulling a rough section out of a long recording and a second either way is irrelevant — it finishes in a moment rather than minutes, and it does not re-encode, so there is no quality loss at all.
What time formats can I enter?+
Plain seconds ("90"), minutes:seconds ("1:30"), or hours:minutes:seconds ("1:02:03"), with optional decimals like "1:30.5".
Is my video uploaded?+
No. The first trim downloads a one-time engine, then everything happens inside this tab. The video itself is never sent anywhere.
