Describe the change

OpenAI uses the displayed pixel size. Gemini requests 1K resolution in this ratio, then the download fits the selected canvas.

Stopping does not guarantee cancellation of provider processing or charges. Check usage before trying again.

THREE SMALL STEPS

How to replace an image background.

  1. Choose a photo with a clear subject.
  2. Describe the new background and select a provider and image model.
  3. Review the charge notice, generate, and check the subject and lighting.

A new scene around your subject.

Background replacement can place a product on a different studio backdrop or give a photo a new setting. Describe the surface, light and atmosphere you want, and specify what should stay unchanged. A simple, clear request gives the model a more focused task.

The model may alter the subject, its outline, shadows or perspective. This page uses prompt-based editing rather than a guaranteed subject cutout. Check small details before using the result for a product listing or any situation where accuracy matters.

For transparent cutouts from plain backdrops, use the free background-colour remover. It exports a real alpha channel without an AI call. This BYOK page is for generating a replacement setting and does not guarantee a transparent-background result.

A FEW USEFUL DETAILS

Before you download.

Does this create a transparent cutout? +

This page replaces the background using a prompt. Use the free colour-and-brush remover for a transparent cutout from a simple backdrop.

Can the subject change? +

Yes. Generative editing can modify fine details. Review the result carefully.

Can I cancel an AI request? +

You can stop waiting, but a provider may still process or charge an already-started request. Check your provider usage before trying again.

ANOTHER WAY TO WORK

Keep creating.
