One shape for every vertical app
9:16 is the full-screen vertical shape used by TikTok, Instagram Reels, YouTube Shorts and Stories. 1080×1920 is the standard size, and this tool outputs it as an H.264 MP4 that all of them accept.
Going from 16:9 to 9:16 means choosing what to lose. Fill the frame keeps only the middle third of a landscape video, which works for a talking head in the centre. Blurred background keeps the whole picture across the width, with a blurred copy filling the space above and below. Black bars does the same with plain black.
Re-encoding happens in your browser, so it takes a while on long videos. Pick the 720×1280 output if you want it faster.
