# border.video > Add a border or frame to any video in your browser: white, black, rounded, Polaroid or blurred, and pad it to square or 9:16. Free, no upload, no watermark. border.video is a browser app: it opens a video from the visitor’s device, draws a border, frame, rounded corners, padding or caption into every frame with WebCodecs, and saves a new MP4 or WebM locally.

Nothing is uploaded, and there is no API or account system. ## The tool and its guides - [Add a border to a video](https://border.video/): The framing tool: eight looks, five shapes, per-side widths, corners, shadow, caption, collage. - [Add a white border to a video](https://border.video/add-white-border-to-video): The gallery look: an even white frame, in percent or exact pixels. - [Make a video square without cropping](https://border.video/make-video-square): Fit the full picture in a 1:1 frame and fill the gaps with colour or blur. - [Add a border to a video for Instagram](https://border.video/instagram-video-border): Fit a whole clip into a 4:5 post or a 9:16 Reel without Instagram cropping it. - [Fit a landscape video to 9:16 without cropping](https://border.video/fit-video-to-9-16): Make a vertical video for TikTok, Reels or Shorts and keep the whole picture. - [Add a blurred background to a video](https://border.video/blur-background-video): Fill black bars with a soft blur of the clip, in a 16:9 frame or any shape. - [Add a Polaroid or film-strip frame to a video](https://border.video/add-frame-to-video): Instant-photo, film-strip and card frames, with an optional caption. - [Add rounded corners to a video](https://border.video/rounded-corners-video): From a gentle curve to a pill shape, on any border colour. - [Add a border to a video in CapCut](https://border.video/add-border-to-video-capcut): Canvas colour or blur, a new ratio, and a smaller clip: the CapCut method. - [Add a border to a video in iMovie](https://border.video/add-border-to-video-imovie): Picture in Picture over a coloured background, on Mac and iPhone. - [Add a border to a video in Premiere Pro](https://border.video/add-border-to-video-premiere-pro): Colour matte, the Stroke effect, or a rectangle with a stroke. - [Add a border to a video in Canva](https://border.video/add-border-to-video-canva): Stroke style, Frames and a background colour, Canva’s three ways. - [Add a border to a video on iPhone](https://border.video/add-border-to-video-iphone): No border in Photos, so use Safari (no app) or iMovie. - [About](https://border.video/about): Why border.video exists, how it draws frames in the browser, and its promises. - [Privacy at border.video](https://border.video/privacy): Videos never leave the device; Google Analytics counts visits and can be switched off in Cookie settings. ## What the border tool does - **Live looks on your own clip**: Eight ready-made frames, from Clean white to Film strip, previewed on a still from your video before you pick one. - **Pads, never crops**: Change the shape to square, 4:5, 9:16 or 16:9 and the whole picture stays in view. The space around it becomes border. - **Private and free**: Framing happens on your device. No upload, no account, no watermark, and no cap on length beyond what your device can handle. ## Framing a clip in three steps 1. **Open your video**: Drop a clip on the page or choose one from your files. It appears straight away inside a clean white border. 2. **Choose a look and a shape**: Tap a look such as Soft rounded or Polaroid, pick a Shape for where the video is going, and drag Border width until it feels right. 3. **Export and download**: Press Export video. Your browser draws the border into every frame, keeps the sound, and gives you an MP4 to download or share. ## Questions about borders and frames ### How do I add a border to a video? Open the video in the tool at the top of this page. It gets a white border at once. Pick another look if you like, set Border width, then press Export video and download the result. It takes a minute and nothing is uploaded. ### How do I add a white border to a video for Instagram? Choose Clean white, then set Shape to 4:5 for a feed post or 9:16 for Reels and Stories. The video is scaled to fit inside the white border, so Instagram has nothing to crop. ### Can I make a landscape video square without cutting anything off? Yes. Set Shape to 1:1. The canvas becomes square and the full frame sits in the middle; the bands above and below are filled with your border colour, a gradient or a blurred copy of the video. ### Does adding a border lower the quality? The border is drawn into each frame, so the video is re-encoded. With Original shape the picture keeps its own resolution and the canvas grows to hold the border. Quality set to High keeps the file very close to the source. ### Can I make the border thicker on one side, like a Polaroid? Yes. The Polaroid look already has a deep bottom edge. For full control, open More options and turn off Same width on every side, then type the top, right, bottom and left widths, in percent or pixels. ### Can I write a caption in the border? Yes. Turn on Caption under More options (Polaroid turns it on for you), type your text, and choose the font, size and colour. It is drawn in the bottom border of every frame. ### How do I round the corners of a video? Pick Soft rounded, or open More options and drag Corner radius. The corners are cut cleanly and the border shows through, so they look rounded on every player and platform. ### What is the blurred background option? Blurred background fills the border with a soft, enlarged copy of the video itself, the way TV channels show vertical phone clips. It works best when you change the shape, for example a portrait clip in a 16:9 frame. ### Can I put several videos in one frame? Yes. Press Make a collage (or drop two or more videos at once) to place 2 to 6 clips in one frame, with the same border round the outside. You choose the layout, which part of each clip shows, and whose sound to keep. ### Is my video uploaded anywhere? No. The tool runs in your browser with WebCodecs and the open-source mediabunny library. The file is read, framed and saved on your own device. ### Which formats can I open and save? Phone and camera files in MP4 or MOV work best, and WebM and MKV usually open too. Rarer codecs get converted on your own device before framing. The result is an MP4, or a WebM if you pick it and your browser can make one. ### Does it work on a phone? Yes, in current versions of Safari, Chrome, Edge and Firefox on iPhone, Android and tablets. When the export finishes, tap Share to send it to Photos or an app, or Download video to keep the file. ### Is it really free, with no watermark? Yes. There is no charge, no sign-up and no mark added to your video. Longer or larger files simply take your device more time.
