For social posts that look best square — Instagram feed videos, Facebook posts, and ads that need a 1:1 frame.
Square (1:1) video still performs well in social feeds because it takes up more vertical space than a landscape clip without going fully vertical. This tool crops your video to a clean 1:1 square in the browser, with a zoom control to choose which part of the frame to keep centered. It's ideal for Instagram and Facebook feed posts, square video ads, or any placement that calls for a balanced 1:1 frame. As with all the crop options here, processing is local — your video never gets uploaded — and the export has no watermark and needs no sign-up, so the result looks professional. Drop in a landscape or vertical clip, switch to the square ratio, frame it with zoom, and download a 1:1 video ready to post. It's the quick, private way to reformat footage for square placements without a desktop editor or a paid online tool.
