border.video puts a frame around a video and changes its shape without cropping. Choose from over 400 looks, from clean white and Polaroid-style to film strips, neon and phone mockups, set 1:1, 4:5, 9:16 or another ratio, and fill the extra space with a colour, gradient, picture or a blurred copy of the clip, so a landscape video fits Reels or TikTok with nothing cut off. Export an MP4 or save a PNG still. No account, no watermark, nothing uploaded.
Posting a landscape clip to a vertical feed usually crops people out of the shot, and the apps that add borders tend to stamp a watermark. border.video was built to reshape and frame videos for any platform in the browser, free and without uploads.
