For marketers preparing one video in the multiple aspect ratios ad platforms require.
Ad platforms specify aspect ratios per placement — vertical 9:16 for Stories and Reels ads, square 1:1 for feed ads, widescreen 16:9 for in-stream — and a mis-shaped video gets letterboxed or rejected. This tool lets you crop one source video into the exact ratio each placement needs, in your browser, with a zoom control to keep your product or message in frame. It runs locally, so your campaign footage isn't uploaded, and the export has no watermark and needs no account — essential for a professional ad. Reframe the same clip to 9:16, 1:1, and 16:9 to cover every placement from a single recording. Drop in the video, pick the ratio, frame it, and download. It's the free, private way to produce ad-ready video in multiple aspect ratios without a desktop editor — and without the watermarks or upload requirements of typical online tools.
