Who is Letterbox Pad for?

Letterbox Pad suits creators fitting video into fixed layouts, such as square feeds or specific player dimensions. Use it when you want to keep the entire original frame and simply pad the edges to match a required shape.

How is Letterbox Pad different from cropping?

Cropping removes part of the image, while Letterbox Pad keeps everything and adds space around it. This makes the each::labs tool the right choice when preserving the full composition matters more than filling the whole canvas.
