# Trim a video in your browser

Pick a video, type a start and end time, and choose a mode. Fast copies the original stream, so it finishes in seconds and keeps full quality, but the cut starts on the nearest keyframe. Accurate re-encodes to MP4 and cuts on the exact time you typed. The file stays on your device.

Runs on your device

## How it works

1. Choose a video file from your device.
2. Type the start and end as minutes and seconds, such as 1:30 and 2:05.
3. Pick Fast to keep the original quality, or Accurate for an exact cut.
4. Press Trim video, check the preview, and download the clip.

## Key facts

- **Formats**: MP4, MOV, WebM, MKV, AVI and M4V
- **Fast mode limit**: 500 MB on a computer, 250 MB on a phone
- **Accurate mode limit**: 120 MB on a computer, 60 MB on a phone
- **Output**: Always MP4. Fast mode keeps H.264 or HEVC quality untouched
- **Encoding speed**: A minute of 1080p at 30 fps took about 8 seconds on an Apple M4 Pro laptop using its video hardware, and 2 to 4 minutes on the fallback engine. Phones and older computers take longer.

## Questions

### Why does my Fast trim start earlier than I typed?

Fast mode copies existing frames, and a video can only start on a keyframe. How far apart they sit depends on the camera or app, and some files have them many seconds apart. If the exact frame matters, use Accurate.

### Which mode should I use?

Start with Fast. It takes seconds, loses no quality and works on larger files. Switch to Accurate when the start of the clip has to land on a specific moment and you can wait for the encode.

### How do I write times over an hour?

Use hours, minutes and seconds separated by colons, such as 1:02:30. Plain seconds such as 95 also work, and decimals such as 0:12.5 let you cut between whole seconds.

### Is my video uploaded anywhere?

No. The video engine runs inside your browser tab and reads the file from your device. ToolSugar's servers never receive it, and closing the tab clears the working copy from memory.
