border.video

Post a widescreen clip to a vertical feed and the app usually crops the sides off. border.video goes the other way. When you change the shape to square, 4:5, 9:16 or 16:9, the whole picture stays in view and the space around it becomes border. You fill that space with a colour, a gradient or a blurred copy of the video itself. There are seven ratios in all, from 9:16 to 21:9.

That's the problem the team behind it set out to fix. They say posting a landscape clip to a vertical feed usually crops people out, and that the apps which add frames tend to stamp a watermark or need an upload. So they built this to frame and reshape a video for any platform in the browser, free. They're also upfront about what it isn't: it frames and reshapes clips, and it's not a full editor.

A clip dropped on the page appears inside a clean white border straight away, and you drag Border width until it looks right. That's only the starting point. There are more than 400 looks in 25 categories. Some are simple, like solid colours, gradients and duotone. Others have more character, such as instant photos, film strips, neon and picture frames. There are generic phone, laptop and TV mockups, and seasonal sets for holidays such as Christmas, Diwali and Eid, plus weddings and birthdays. You search them by name, colour or occasion, and in a nice touch each is previewed on a still from your own video.

A caption can sit in the bottom border, with your choice of font, size and colour.

Collages get the same treatment. Press Make a collage, or drop two or more videos at once, to place two to six clips in one frame with the same border round the outside, in a layout you choose. Photos open in the same editor, and a JPEG, PNG or WebP picture gets every look, shape and border setting a video does.

One trade-off is stated plainly in the FAQ. The border is drawn into each frame, so the video is re-encoded. With the Original shape the picture keeps its own resolution and the canvas grows to hold the border. Longer or larger files take your device more time.

There's no charge, no sign-up and no mark added to your video. According to the privacy page, updated November 6, 2026, your videos are never sent to the site, and the border, frame, caption or collage is drawn by your own browser. No person or company is named as the operator. If you post the same clip to several platforms and hate losing the edges, this one is worth a bookmark.
