Cut your video down to a new shape, square for a feed post, tall 9:16 for Reels, or any common ratio, and decide which slice of the frame survives. It all runs on your device: nothing is uploaded, there's no account, no watermark, and no cost.
Cropping changes shape, resizing changes size
Cropping throws away the parts of the picture outside the box you draw, so the subject fills more of a new frame. Resizing keeps the whole frame and stretches or shrinks it to different pixel dimensions. If a landscape clip has empty space on the sides and you want a tight vertical for TikTok, crop it, that removes the dead edges instead of squashing everything into a narrow box. Reach for resize only when you need specific output dimensions with nothing cut.
Drag the box to frame exactly what you want
Drag anywhere inside the box to move it, and pull the corner or edge handles to resize. Everything outside the box is dimmed so you can see precisely what will be kept, and rule-of-thirds guides help you line up a subject. Because the box maps directly onto the source pixels, what you see is what you get, no guessing about anchors or offsets. Take a moment to scrub the video first so the box covers your subject across the whole clip, not just the opening frame.
Lock a ratio when the destination demands one
Leave the crop freeform when you just want to trim dead space or reframe loosely. Lock a ratio when the target has a fixed shape: square 1:1 for an in-feed Instagram or Facebook post, vertical 9:16 for TikTok, Reels, and YouTube Shorts, portrait 4:5 for the Instagram feed (it claims more height than a square), landscape 16:9 for YouTube, or classic 4:3 for older displays. With a ratio locked, the box keeps that exact shape as you resize, so you can't accidentally drift off-spec.
Tips
- Scrub through the clip before exporting, set the box so your subject stays inside it for the whole video, not just the first frame.
- Crop rather than resize when a landscape clip has empty side margins you want gone, you keep the subject sharp instead of stretching it.
- Lock 9:16 for full-screen vertical, and drag the box up so a talking head isn't clipped at the top.
- Lock 4:5 for Instagram feed posts, more screen height than a square without committing to full vertical.

Questions
- What's the difference between cropping and resizing?
- Cropping removes the parts of the frame outside the box you draw, so the shape changes and some picture is discarded. Resizing keeps the whole frame and changes its pixel dimensions. Use crop to reframe, resize to hit an exact size.
- How do I crop a video to a square or vertical?
- Set the aspect lock to 1:1 for square or 9:16 for vertical, then drag the box over the part of the frame you want to keep. The box holds that shape as you resize it, and export gives you the cropped clip.
- Can I pick exactly which part of the frame is kept?
- Yes. Drag the crop box anywhere on the video and pull its handles to resize. Everything outside the box is dimmed so you see precisely what survives, you're not limited to fixed positions.
- Does cropping reduce quality?
- Cropping itself doesn't blur the picture, it keeps the original pixels inside the box. The video is re-encoded once on export, so pick the High quality preset if you want to preserve as much detail as possible.
- Are my files uploaded anywhere?
- No. The video is cropped entirely on your device and never leaves it, there's no server, no account, and no watermark.
