How tools work

A tool is a small app you describe in plain words. Try this one here, then keep it on your Fuser canvas and connect it to the rest of your work.

Resize video for different layouts

Create versions of one video for common portrait, square, standard, classic, and widescreen compositions.

Vertical 9:16 video

Set the aspect ratio to 9:16 for a tall video layout, then adjust the crop focus to keep the important area visible.

Square 1:1 video

Use the 1:1 option to create a square version of your video for compact feed or profile layouts.

Portrait 4:5 video

Choose 4:5 when you need a portrait video that is taller than it is wide without using a full vertical frame.

Standard widescreen 16:9

Select 16:9 to reshape a video for a conventional widescreen composition.

Classic 4:3 video

Use the 4:3 ratio to create a more traditional video frame from your source clip.

Ultrawide 21:9 video

Choose 21:9 for a broad cinematic-style frame, using crop, blur, or black fill to handle the shape change.
