About MP4 to TikTok
TikTok lives in vertical, full-screen video, and a clip shot horizontally or in the wrong proportions can end up letterboxed or awkwardly cropped. Getting your MP4 into the right vertical shape before you upload makes it look like it belongs on the platform.
This tool reformats your MP4 for TikTok's vertical video layout, so it fills the screen the way viewers expect. It runs in your browser, free, with no signup and no watermark added to your video. Upload the MP4, let the tool adjust the format, and download a version ready to post. It's an easy way to prep footage for TikTok without opening a full video editor.
