How do I turn a landscape video into vertical?

Drop your clip into Crop Video, choose the Vertical 9:16 preset, and click Crop & export. The centre of the frame is kept and the sides are trimmed, then downloaded as an MP4 — all in your browser.

Does cropping add black bars to my video?

No. Cropping fills the frame by trimming the edges, so there are no bars. If you want to keep the whole picture and pad the extra space instead, use the Video Resizer tool.

Can I remove black borders from a video?

Yes. Choose the aspect ratio that matches the actual picture and the center crop will cut the surrounding bars away, leaving just the content.

What part of the frame is kept when I crop?

The center. Crop Video takes the largest rectangle of your chosen aspect ratio from the middle of the frame, so anything near the trimmed edges is removed.

What aspect ratios can I crop to?

You can crop to square 1:1, vertical 9:16, portrait 4:5 and landscape 16:9. Each preset exports a standard MP4 at that ratio.

Is my video uploaded when I crop it?

No. Crop Video runs entirely in your browser. The file is read from your device, cropped locally, and never sent to ArrayKit or any server.

About Crop Video

Crop Video reframes a clip by keeping the centre and trimming the edges, so the picture fills the target frame with no padding. Turn a landscape recording into a vertical 9:16 for Reels and Shorts, cut a wide video down to a square 1:1 or 4:5 portrait, or reclaim a proper 16:9 by shaving black borders off the sides. Choose an aspect ratio, export, and download a clean MP4 that is framed exactly the way you want it. It works on MP4, MOV, WebM and more, and everything runs on your own device: the file is read locally, cropped locally, and never sent to a server. Ideal for repurposing screen recordings, focusing on a subject in the middle of the frame, or tidying up footage before sharing it.

Common errors & troubleshooting

Cropping landscape to vertical cut off people at the edges. — A center crop keeps the middle of the frame, so subjects on the far left or right are trimmed. Reframe your source so the subject is centred, or use Video Resizer to keep the whole picture with padding instead.
Black borders are still visible after cropping. — Pick the aspect ratio that matches the real picture inside the bars — for a pillarboxed clip choose a wider ratio, for a letterboxed one choose a taller ratio, so the crop lands on the content.
Cropping a long 4K video is slow. — The video is re-encoded locally in a single browser tab. Crop a shorter clip, or compress it afterwards if you also need a smaller file.
