Cut a video’s frame down to the area you want and export it as a new file. Drag the box over the preview, pull its handles, or type the rectangle in pixels.
Frame the crop
The dimmed area around the box is what gets removed. Drag inside the box to move it and drag a handle to resize it. The thirds lines inside the box help place a subject off center.
The rectangle is stored in the page address as fractions of the frame, so a shared link applies the same framing to another file, even one at a different resolution.
Aspect ratios
| Ratio | Where it fits |
|---|---|
| 16:9 | YouTube, laptops, TVs |
| 9:16 | Shorts, Reels, TikTok, Stories |
| 1:1 | Square feed posts |
| 4:5 | Portrait feed posts |
| 4:3 | Older cameras, slides |
| 2:1 | Univisium, streaming features |
| 21:9 | Ultrawide |
| 2.35:1 | CinemaScope |
Fourteen ratios are in the list, and each one also has its own page if you already know which you need.
With a ratio chosen, the box resizes from its corners only and keeps the ratio. Changing the ratio recenters the box at the largest size that fits. Free unlocks the edge handles and the pixel fields.
Crop, fit, or stretch
Frame mode decides what happens to the picture the new ratio does not have room for.
Crop to fill cuts it away. Going from 16:9 to 9:16 this discards about 70% of the frame, which is right when a single subject sits near the middle and wrong when the composition needs its edges.
Fit with bars keeps every pixel and pads the rest. The output is the target ratio at the source’s long edge, so a 1920x1080 clip at 9:16 exports 1080x1920 with the picture 1080x608 across the middle. The bar size is shown under Output before you export.
Stretch to fill distorts instead of cutting or padding. It is honest only on footage with no recognizable geometry.
Bars
A blurred copy of the frame is the usual choice when a landscape clip goes vertical: it fills the space with something that moves, and it reads as deliberate. The worker draws the frame twice, once scaled to cover with a blur behind, once contained on top.
Black is the conventional letterbox and the safest choice when the clip will be re-encoded again later. White suits light documents and screen recordings. A custom color matches brand bars.
Pixels and rotation
All values are in the orientation the video plays in. A phone recording stored sideways with a rotation flag is shown and measured upright, and the export has the rotation applied to the pixels.
Resolution cap
The cropped frame is exported at its own size by default. A 1080p or 720p cap scales it down when it is larger, never up. Both sides are rounded to even numbers, which H.264 requires.
Audio
The soundtrack is copied when the output container supports its codec, and re-encoded when it does not. Remove audio exports a silent clip.
