Crop Video
Crop to 9:16, square or any area you drag.
Keep Only the Part of the Frame That Matters
Turn a widescreen clip into a vertical 9:16 video for Reels, Shorts and TikTok, a square for a feed post, or a tight crop that removes black bars, a watermark in the corner, or an untidy edge. Drag the box over the area to keep, resize it by the corners, or choose a shape and let the tool fit the largest box it can.
The cropped area is then re-recorded at its own full resolution by your browser’s video encoder, in real time and with the sound if you keep it. Nothing is uploaded, and there is no watermark.

Frequently asked questions
Does cropping reduce the resolution?
The output is exactly the cropped area’s pixels. Cropping a 1080p video to 9:16 gives about 608 × 1080 — use a 4K source for a full-resolution vertical video.
Can I follow a moving subject?
Not in this tool: the crop stays in one place for the whole clip.
Why does it take as long as the video?
The crop is re-recorded in real time by your browser’s own encoder, which avoids uploading the file.
Can I crop and trim at once?
Trim first with the Video Trimmer, then crop the shorter clip here to save time.
How do I turn a horizontal video into a vertical one for TikTok?
Choose the 9:16 shape, drag the box over the subject and crop. Because a vertical frame shows only part of a widescreen shot, keep the important action near the middle of the original video, or record in 4K so the crop still has plenty of pixels.
