Does replacing the background upload my photo?

Yes. The AI scene swap on this page sends the image on the layer you picked to the cloud; the button carries a cloud icon you can see before tapping. If all you want is a flat colour or a photo you already have, the local cutout path is enough — that one runs in the browser, your image never leaves the device, and it needs no account.

Does swapping the background send my image to the cloud?

Yes. Painting a new background takes a large model, which doesn't fit in a browser, so that step runs in the cloud and sends the image on your selected layer. No sign-up, free credits every day. The editor itself — plus cutout, compression, filters and PSD read/write — needs no account; apart from cutout, which downloads a model of about 100MB the first time (your browser caches it after that), all of it works offline.

Can it cope with fine hair around the subject?

It's handled by a cloud model, and the request it gets is to replace only the background and leave the subject as it is — the result depends on the model. Extreme cases like backlit flyaway hair or reflections through glass can still show flaws — after the swap you can fix that small patch yourself with a mask and brush.

Can I use a background image of my own?

Yes, and that path needs no cloud AI: open your photo, remove the original background with cutout, then use File > Place… to bring in your background image and drag it below the cut-out layer. Position, scale and brightness are all yours to adjust. The cutout and the stacking are computed in your browser; when you're signed in, the editor saves the work automatically to your cloud projects.

"Replacing the background" covers two different jobs. One is swapping in a flat colour: cut out the subject, lay a colour underneath. That can be done entirely inside your browser (the Background Remover and ID Photo Background pages do it on the spot, with five backgrounds — transparent, white, blue, red and grey — and the image never leaves your machine) — no account, no limit; to use a picture of your own instead, go into the full editor, cut out the subject and put that picture on the layer underneath (see the Q&A below). The other is a scene that doesn't exist yet ("a beach at dusk", "a plain grey studio"), which needs a large model to generate a new background while leaving the subject as it is. That one runs in the cloud.

This page is about the second one. It sends the image of the layer you selected to the cloud; in the AI panel it carries a cloud icon next to its title, visible before you click. The result replaces the selected layer, and Ctrl+Z undoes it; to keep the original, duplicate the layer first. Afterwards you can still move it, resize it and change its opacity.

Key features

Edges follow the subject instead of being pasted

Stray hair, soft fur and sheer fabric are where cut-outs give themselves away. Those transitions are left to the model, and how they turn out depends on the model; if an edge still isn't right, adjust the description and tap “Replace background” again, or step back with Ctrl+Z.

It comes back as a layer

The new image replaces the layer you selected (person and new background in the same layer); if it's not right, Ctrl+Z undoes it, and to keep the original, duplicate the layer first. If you want person and background on separate layers to adjust each one, take the local cutout path: cut the person out and put a background image underneath.

Describe the scene in plain words

"A beach at dusk", "a plain grey studio with light from the left" — direction, time of day and colour all work. Not right? Adjust the description and tap “Replace background” again (it sends the current version of the selected layer); press Ctrl+Z to get back to the original.

If you only need a plain colour, there's a path that uploads nothing

ID photos on white/blue/red, product shots on pure white — local cutout handles those, with nothing leaving your device and no sign-in. That path lives on the ID-photo and background-remover pages.

How to use

1
Drop the photo in

Anywhere on the page catches it. You can also click to pick a file, or just press Ctrl+V to paste a screenshot.
2
Pick the layer to work on

The panel labels each layer L1/L2/L3. Usually there's only one, so you can go straight on.
3
Describe the background you want

In the AI panel, spell out the scene, the light direction and the colour. This step sends that layer's image to the cloud — the button shows a cloud icon.
4
Adjust and export

The swapped image sits on the layer you selected — move it, scale it, lower its opacity (if you duplicated the layer first, the original is underneath). When you're happy, export PNG / JPG / WebP / PSD, no watermark.
