Three steps, zero upload

  1. Drop your video

    MP4, MOV or MKV up to 500 MB and 30 minutes. The file is opened locally — nothing leaves your device.

  2. Set start and end

    Enter the seconds to keep. Cutting uses stream copy — no re-encode, so quality is bit-for-bit and it finishes fast.

  3. Download the clip

    Save it instantly. Billing follows the clip: a 10-second cut costs 0.1 credits.

Frequently asked questions

Does my video upload anywhere?

No. Trimming runs entirely in your browser with WebAssembly. The file never leaves your device — that is the whole point of this tool.

Is the quality re-encoded?

No. Cutting uses stream copy — the frames are copied as-is, so there is no quality tax. The cut lands on the nearest keyframe, which for typical clips is imperceptible.

How does billing work?

You pay for the clip, not the source: 0.1 credits per minute of output. A 10-second cut costs 0.1 credits; your free trial credits cover it.

How long can the video be?

Source files up to 30 minutes. Local cutting is limited by your device memory, not by a queue.

Which browsers work?

Chrome and Edge are fastest. Safari and Firefox work too; big files are tighter on memory there.
