How it works
Cropping video is how you remove a black border from a downloaded clip, cut a distracting edge out of a screen recording, or tighten a shot onto its subject. It is different from resizing: nothing is scaled, pixels are simply discarded from the edges.
Drag on a real frame
A still is taken from early in the clip and shown for you to drag on, so you are selecting against the actual picture rather than guessing at coordinates. The selection is applied to every frame.
Dimensions are rounded to even numbers
H.264 requires both dimensions to be even, so each edge of your selection is rounded to the nearest even pixel. The difference is at most one pixel per edge and is never visible.
Cropping does not scale
The kept pixels stay at their original resolution, so the picture does not soften. The output is simply a smaller frame — which also means a smaller file.
Clips your browser cannot preview
Formats with no browser decoder, such as WMA-era containers, cannot show a still to drag on. ffmpeg can still crop them, but without a preview this tool has nothing to display, and it will say so rather than guess.
Crop a video — questions
Does cropping reduce the quality?
No. The kept pixels are not scaled, so they stay exactly as sharp as the original.
Is the crop applied to the whole clip?
Yes. The area you choose on the preview frame applies to every frame.
Why did my selection shift by a pixel?
H.264 needs even dimensions, so each edge is rounded to the nearest even pixel.
Is my video uploaded?
No. Cropping runs in your browser.
