About this tool
Keep exactly the area of a video you need. Drag and resize the selection box directly over the preview, then export the selected frame area as a new MP4. Video decoding and encoding happen entirely on your device, so your file is never uploaded.
How to use
- Click or drag to select a video file
- Play or pause the preview at a representative frame
- Drag the selection box and its handles to choose the area to keep
- Click "Crop video" and download the new MP4 file
FAQ
Will cropping reduce video quality?
Cropping changes every video frame, so the video must be re-encoded. The tool uses high-quality AVC settings, but a small quality trade-off is unavoidable compared with the original file.
Can I crop to a specific aspect ratio?
The selection is freeform, so you can make it square, portrait, landscape, or any custom ratio. The output keeps the exact selected dimensions.
Why does cropping a long or 4K video take time?
Every frame is decoded, cropped and encoded locally by your browser. Processing time depends on the video length, resolution and your device performance.
Are my videos uploaded to a server?
No. All decoding and encoding runs locally in your browser. Your files never leave your device.
