How to remove the background from a video
- Add your video. Drag an MP4, MOV, WebM or MKV file onto the box above, or click Choose video. The file opens in your browser; nothing is sent to a server.
- Check the preview. The tool cuts out the subject on one frame so you can judge the result before processing everything. Move the slider to check other moments, and switch between Original and Result to compare.
- Pick a method. AI cutout finds people automatically in normal footage. Color key is for clips filmed in front of a green or blue screen.
- Choose the background. None gives a transparent video. Color fills the background with a solid color, such as pure green for a new green screen. Image places your subject on a picture, and Blur keeps the original scene but out of focus.
- Export and download. Choose 720p, 1080p or the original size, then click Export video. A progress bar shows the speed and the time left. When it finishes, download the file.
Why use this video background remover
Most online tools that remove the background from video upload your clip to their servers, process it there and then sell you credits to download it in full quality. This video background remover works differently: the AI model runs inside your browser, on your own processor or graphics card.
- Private. Your footage never leaves your device. That matters for client work, unreleased content and anything personal.
- Free and without a watermark. No credits, no subscription and no logo stamped on the result.
- No upload wait. A 500 MB file starts processing as soon as you drop it, because there is nothing to upload.
- Full resolution. Export at the original size of your clip, not a preview size held back for paying users.
- Real transparency. The transparent export is a WebM file with an alpha channel, not a video on a checkerboard.
The only download is the AI model itself, about 15 MB. Your browser saves it after the first visit, so the tool starts much faster next time.
AI cutout or color key: which should you use?
| AI cutout | Color key | |
|---|---|---|
| Best for | People in everyday footage: vlogs, interviews, webcam clips, dance and sports videos | Clips filmed on a green or blue screen |
| Needs a green screen | No | Yes, or any evenly lit single-color background |
| Hair and motion | Handles hair and movement well; it remembers previous frames, so edges stay steady | Exact on a clean screen; struggles with wrinkles, shadows and green clothing |
| Speed | Fast on a GPU, slower on a CPU | Very fast on any device |
The AI is trained on people. It usually also keeps things a person is holding or wearing, but it is not designed for cars, products or animals on their own. For those, a green screen and the color key give a cleaner result.
Export options for a video without a background
Transparent WebM
Choose None as the background to get a video with a real alpha channel. Use it as an overlay in OBS, on a website with the HTML video tag, or in any editor that reads WebM with transparency. See the transparent video maker page for details on where it works.
Green screen MP4
Choose Color and keep the default pure green. The result is an ordinary MP4 that every editor can open; key the green out in Premiere Pro, Final Cut, DaVinci Resolve or CapCut and place the subject anywhere you like.
New background
Choose Image and pick a photo to put behind the subject, or use the video background changer for a guided version. The image is scaled to fill the frame.
Blurred background
Choose Blur to keep the original room but soften it, like portrait mode on a phone. The blur video background page explains how to pick the right strength.
Tips for a clean result
- Light the subject well. The AI separates a person from the background more easily when the person is clearly lit and the background is not the same color as their clothes.
- Use Shrink / expand. If a thin halo of the old background remains around the edges, move the slider a little to the right. If fine hair is cut off, move it to the left.
- Add a small feather. One or two points of feather softens hard edges so the subject blends into a new background.
- Check several moments. Drag the preview slider to a fast movement or a moment with hands near the face before you export.
- For green screens, use the eyedropper (Pick from video) on the screen itself, then raise Tolerance until the screen disappears and lower Softness if edges look see-through.
How fast is it?
Speed depends on your hardware, the export size and the method. As a rough guide for 720p video with the AI cutout:
- A computer with a dedicated graphics card in Chrome or Edge: the fastest option, many frames per second.
- A laptop with integrated graphics: slower, but still well ahead of the CPU.
- CPU only, in a browser without WebGPU: around two to three frames per second, so a one-minute clip takes several minutes.
The color key is much lighter and runs quickly on almost any device. The progress bar always shows the measured speed and the time left, so you know what to expect. Exporting at 720p instead of 1080p roughly halves the work.
What people use it for
- Cutting a presenter out of a webcam recording to place them over slides or a screen capture.
- Making a talking head overlay for YouTube, TikTok or Instagram Reels.
- Turning a normal clip into green screen footage that an editor can key.
- Creating a transparent video for a website hero section or a stream overlay.
- Hiding a messy room behind a blurred or replaced background.
