Remove the source's solid-color screen
Open an image or supported video and sample its backdrop. Refine the key before adding a busy scene so leftover screen patches are easier to find.

How to use the background replacer online
02
Choose a color or upload a background photo
Select a preset, a custom color, or Custom image. The uploaded image fills the canvas using a centered crop, so use a background with room around its important details.
03
Inspect the composition and download
Check lighting, contrast, and the subject's edges against the new scene. Export PNG, WebP, or JPG for a still image, or record an opaque MP4 or WebM for supported video.
Replace a green screen with a photo that fits your canvas
The source sets the canvas dimensions. A replacement image is scaled to cover that canvas and cropped centrally when its aspect ratio differs. A portrait background in a wide video can lose its top and bottom; a wide photo in a portrait canvas can lose its sides.
Prepare a background with a similar aspect ratio when exact framing matters. Keep faces, text, and other important elements away from the edges. This editor does not provide manual background positioning or a second video layer.
Make a green screen composition look more consistent
Choose a background whose lighting and perspective suit the subject. A softly lit face against a harshly lit scene can look pasted in even when the matte is clean. A neutral color is useful for checking the key before choosing the final scene.
Keying is still based on color. Replacing a backdrop does not add AI segmentation for a busy room or street. If the source has no distinct screen, a color selection may also remove parts of the subject. Use the original/result comparison and review the downloaded composition.
What to know before using this background replacer
- Backgrounds are still images or colors; a video background is not supported.
- Centered cover cropping can remove the outer parts of a background image.
- A complex source background is not automatically separated from its subject.
PRACTICAL ANSWERS
Background replacer questions and answers
Formats, useful settings, and the details that affect your result.
Can I put my own photograph behind a green screen video?+
Yes. Remove the screen, select Custom image, and choose a local PNG, JPG, or WebP photo. The photo is scaled and centered to fill the source canvas.
Why is part of my replacement background cropped?+
The background uses a cover fit. If its aspect ratio differs from the source, it is enlarged until the canvas is filled and the excess is cropped from the center.
Can I change the position of the background image?+
The current editor centers the background automatically. Crop your background to the intended aspect ratio beforehand when you need more control over which area is visible.
Can I replace a background without a green or blue screen?+
You can key another distinct solid color, but the tool does not perform AI segmentation. A busy scene or colors shared by the subject are difficult to separate accurately.
Do replacement background images leave my device?+
They are read locally for Canvas compositing and are not uploaded for processing. Ordinary website and asset requests are separate from your media.
