What is Crop Video?
Crop Video removes unwanted edges — a watermark strip, black bars, a messy background — and keeps the part you choose. Drag the crop box on the preview or its corner handles, lock it to 16:9, 9:16, 1:1, 4:5, 4:3 or 3:4, or type X, Y, width and height in pixels. The box always stays inside the frame. Everything runs in your browser; your video is never uploaded.
Crop videos online with a visual crop box on the preview, aspect-ratio presets and exact numeric fields. Free video cropper on Fah Swe Tools — processing runs locally in your browser.

Troubleshooting
- I don't see a preview, only number fields Your browser can't play this video format, so the visual box is unavailable. The numeric fields still work and the crop is processed normally.
- The crop box won't go further It is kept inside the video frame. Make it smaller or move it first.

FAQ
Can I crop to an exact size?
Yes. Type X, Y, width and height in pixels; the box on the preview follows. Values are kept even and inside the frame because video encoders need that.
Is my video uploaded?
No. Crop Video runs entirely in your browser with WebAssembly. Your file never leaves your device and is never sent to Fah Swe servers.
Why do my numbers change by one pixel?
Video encoders need even widths, heights and offsets, so values are rounded to even numbers.
Can I crop on my phone?
Yes. Drag the box and its handles with your finger, or type the values.
