NSS Background Remover
Compositing with the image editor: layers, blend modes, and filters
Take a cutout further: stack multiple images as layers with blend modes, apply any of 22 filters, drop a subject into a lifestyle scene, and preview in 3D with depth relief — all in the browser.
Cutting out a subject is often step one of a bigger image. The full image editor turns NSS Background Remover from a single-purpose cutout tool into a compositor: layers, blend modes, filters, ready-made scenes, and a 3D/depth preview. This guide walks the editor end to end.
Everything stays local, and you can save the whole composition as a .nss-project file to come back to later.

1. Open your cutout in the editor
After a removal, send the result into the image editor instead of exporting. Your subject arrives on its own transparent layer, ready to combine with other images. You can also bring additional photos in as new layers to build a scene.

2. Work in layers with blend modes
The editor supports multi-file layers, each with its own blend mode. Blend modes control how a layer’s pixels combine with what is beneath — multiply for shadows, screen for light and glow, overlay for contrast. Stack a background photo, your cutout subject, and an accent layer, then reorder and adjust opacity until the composition reads correctly.
Because your subject is on straight alpha, its edges blend cleanly into whatever sits below it, with no halo to clean up.
- Multi-file layers with reordering and opacity.
- Blend modes for realistic shadows, light, and contrast.
- A clean alpha edge composites without fringing.

3. Apply filters and drop into a scene
Use any of the 22 filters to grade the whole image or a single layer — matching color temperature between a subject and a new background is what makes a composite believable. The built-in lifestyle scenes give you ready-made environments to drop a product or portrait into without sourcing your own background.
Match the subject to the scene rather than the other way around: nudge the subject’s exposure and color toward the scene’s lighting, and the eye stops noticing the seam.
- 22 filters, applied per-layer or globally.
- Lifestyle scenes as instant backgrounds.

4. Preview in 3D with depth relief
The editor includes a 3D preview with depth relief, which uses a depth estimate to give the image a sense of dimension — useful for product presentation and for sanity-checking that your subject sits correctly against the background. The AI assistant is on hand for guided edits when you want a suggestion rather than doing every adjustment by hand.

5. Export or save the project
When the composition is right, export a flattened image (PNG/WebP/AVIF), or save the layered work as a .nss-project file so you can reopen and keep editing later. Nothing is uploaded at any point — the project file lives on your device.
Composite like it’s real
The single biggest believability lever is color and light matching between the subject and its new background — spend your time there, not on the cutout, which the AI already handled. Keep layers non-destructive by using opacity and blend modes rather than baking changes in, and save a .nss-project checkpoint before a big change so you can always step back.
