Turn a 16:9 recording into a 9:16 post for Shorts, Reels, or TikTok. Crop in tight, or fill the space with a blurred backdrop so nothing important gets cut off.
or click to choose one. It stays on your device.
Blurred bars keep your whole frame visible and fill the empty space with a soft blurred copy. This is what most creators use when reposting a landscape video.
Your file is being processed on your own device. Keep this tab open.
Crop to fill gives you a true full bleed vertical video with no bars, but it throws away the left and right of your frame. It works when your subject is centred and there is nothing important at the edges. It fails badly on screen recordings, where the thing you are pointing at is usually not in the middle.
Blurred bars keep the entire original frame and fill the space above and below with a blurred, scaled up copy of the video. Nothing is lost, it reads as deliberate rather than lazy, and it is what most creators reach for when reposting landscape footage to a vertical feed.
If you are recording something new rather than salvaging something old, record vertically in the first place. Recording Studio composes your screen and camera into a 9:16 frame live, so there is nothing to reframe afterward.
Any video your browser can play. The tool reads its real dimensions and works from those.
9:16 for Shorts, Reels, and TikTok. 4:5 for the Instagram feed. 1:1 when you want square.
Output is a clean MP4 at the platform standard size, ready to upload.
All three want 1080 by 1920, which is 9:16 vertical, and that is exactly what this tool outputs. They all accept other ratios and letterbox them for you, but you give up screen space and the algorithmic preference that comes with a native full screen post.
It can. Crop to fill takes the centre of the frame, so if you sit to one side of the shot you will lose part of yourself. Use blurred bars when your subject is off centre, or when the video is a screen recording where the edges carry information.
No. The video encoder is compiled to WebAssembly and runs inside this browser tab, so your file is read from your disk, processed by your CPU, and saved back to your downloads folder. There is no upload endpoint. You can confirm it by opening your browser devtools network tab, or by disconnecting from the internet once the page has loaded.
The video is re-encoded, so there is some loss in principle, but it is encoded at a high quality setting and the output is a standard 1080 wide MP4. On normal footage you will not see a difference.
The tool holds your file in browser memory, so it is capped at 600 MB. That covers most screen recordings and phone clips. For anything larger, trim it down first or use a desktop encoder.
Recording Studio records your screen and camera together, composed live, vertical or landscape. Free, no account, nothing uploads.
