The Aspect Ratio tool, every setting, on a real landscape clip of a dog shaking its head. The ratio is the platform: 9:16 for TikTok, Reels and Shorts, 4:5 for the Instagram feed, 1:1 for a square post and 16:9 for YouTube. Fit keeps the whole picture and fills around it — with a blur of the same video, so it never looks like black bars — while Fill crops to the edge for a closer frame, and the anchor decides which part survives the crop. With Fit you choose what goes behind: black, a colour, your own image, or a mirror of the edges. At 720 on the long edge, the 14-second clip comes out 404×720 and under 3 MB — sharp on any phone. Everything runs in your browser, so the video is never uploaded.

A landscape video — and TikTok wants it tall. One press: nine by sixteen, and not a pixel of the dog is cut off.
Aspect ratio, every setting: which ratio for which app, fit or fill, where the crop sits, what goes behind, and the size. Free, and nothing is uploaded.
