How to crop a video

  1. 1

    Drop your video

    The full frame appears with a crop box on top.

  2. 2

    Drag the box

    Move it and pull the corners — or lock a shape like 1:1, 9:16, 4:5 or 16:9.

  3. 3

    Check the result size

    The exact output resolution is shown as you adjust.

  4. 4

    Export

    Only the area inside the box is kept.

Popular ways to use it

Remove black bars

Cut away letterboxing from screen recordings and old videos.

Focus on the subject

Zoom in on a speaker or product by cropping the empty space around it.

Screen recording cleanup

Hide the taskbar, tabs or notifications at the edges of a capture.

Exact aspect ratios

Lock 1:1 or 4:5 for feed posts without any fill.

Tips for the best result

  • Crop keeps the pixels you select at full resolution — cropping a 4K video still gives a sharp result.
  • Rotate first, then crop: the crop box always works on the rotated picture.
  • To fill a 9:16 frame without losing the edges, use "Resize for social" with blur fill instead.

Crop — FAQ

Can I crop to a square?

Yes — pick 1:1 and drag the box to frame your subject.

Does cropping lower the quality?

The kept area is not scaled down, so it stays as sharp as the original. The video is re-encoded once at high quality.

Can I crop to a perfect square?

Yes — choose the 1:1 shape and the box locks to a square.

Can I crop a moving subject?

The crop is fixed for the whole video. Leave some margin around a subject that moves.
