Crop a video to any size or aspect ratio

Drag a box, keep what’s inside

Pick a video, drag the crop box over the part you want to keep, and everything outside it is cut away. Choose a preset if you’re hitting a spec, or drag freely if you’re not.

Nothing is uploaded. The video is processed in your browser, so there’s no wait for a file to travel to a server and back, and nothing leaves your computer.

Presets for the placements that reject off-spec video

Ad platforms are strict about shape. These are the ones people crop for most:

Pick one and the crop box locks to that shape. Drag it around to choose which part of the frame survives.

Cropping is not scaling

Scaling a 16:9 video to 9:16 squashes everyone in it. Cropping takes a 9:16 window out of the frame and discards the rest, so the picture keeps its proportions and you decide what stays.

That’s what this tool does, and it’s why the crop box matters — a centred crop is rarely the right one when the subject is off to one side.
