How to remove or replace an image background with AI
Cutting a subject out of its background used to be a job for a pen tool and an hour. Now it is one click, and the interesting question has moved on: whether to cut out and composite, or to regenerate the scene around the subject. Both are right in different cases.
Cut-out versus regeneration
Automatic background removal detects the subject and returns it on a transparent background. It is fast, cheap and exact for products, logos and clean portraits. It struggles with hair, glass, smoke and motion blur, where the edge is not really an edge.
Regeneration keeps the subject and asks an image model to paint a new environment around it, with matching light and shadow. It is the better choice when the subject needs to sit naturally in a scene, for example a product on a real table instead of floating on white.
Getting clean results
Start from the highest-resolution version you have; edge quality follows input quality. For hair and fur, use a removal model that outputs a soft mask rather than a hard cut. For replacement, describe the new background with the same light direction as the original ('window light from the left') so the composite does not look pasted.
If you are producing many images in the same style, do one, check it at 100 percent zoom, and only then run the batch.
How to do it in Vyndexo
Open the image
Upload the photo or pick a generated image in Media Studio. Every generated image has a Remove background action.
Remove
Run the background remover. The result is saved next to the original in the project as a transparent PNG.
Replace if needed
Use the cut-out as a reference and prompt a new scene, or place it in the Canvas over a generated background.
Export
Download the PNG, or send it straight into a video model as a start frame.
Common questions
Is background removal free?
It uses a small number of Tools credits per image; the cost is shown before you run it. The Free plan can buy a credit pack, no subscription required.
Does it work on AI-generated images?
Yes, and typically better than on photos, because generated images have cleaner edges.
Can I batch-process many images?
Yes, from the project's media view; each image keeps its original alongside the cut-out.
