Each cell is one source pixel. Bright cells are kept, dark cells are cut off. The black-and-white dashed line is drawn just outside the kept area so it never covers a kept pixel.
Drag on the picture to choose the part to keep. Drag inside the box to move it, drag a corner to resize. Only the cropped picture is re-encoded; audio is kept as is.
How to Use
Drop or click to pick an MP4, MOV, WebM or MKV file. Use the slider below to show a different frame.
Drag on the picture to draw a box. Drag inside it to move, drag a corner to resize. You can also pick a ratio such as 9:16 or 1:1, or type pixel values.
Press "Crop & save" to render only the chosen area as MP4. Play the result, then download it.
FAQ
How is this different from Trim Video?
The trimmer cuts time (the start and end); this tool cuts space (an area of the frame). If you need both, shorten the clip with the trimmer first, then crop it here.
Does it lose quality?
The chosen area keeps its original pixels and is not upscaled. Changing the frame does require re-encoding, so there can be a very small difference; it is saved at a high quality setting.
Is the audio kept?
Yes. Audio is copied over without re-encoding.
Why can I not enter odd sizes?
MP4 (H.264) stores color in 2×2 pixel blocks, so position and size are rounded to even numbers. A value may shift by one pixel.
Does it work with iPhone portrait videos?
Yes. Rotation is applied, so pick the area as you see it. If your browser cannot play the codec (HEVC, for example) the preview shows a single frame, and cropping still works.
