Tool ID: replace-background. Requested language: ur. Description language: en. Complete guide translation: no; untranslated sections use English.

## Overview (en)

Replace image background cuts the subject out of one photo and places it on a second image you upload as the new background. The BEN2 segmentation model downloads on first use and runs in a browser worker. The background image is scaled to cover the subject photo's dimensions and centered, and the result is a PNG.

## Supported tasks (en)

Downloads a browser inference model on first run, then processes source locally in a cancellable Web Worker. Background removal uses BEN2; transcription uses Whisper tiny. Review recognition errors and image edges.

## Questions (en)

### How do I change the background of a photo?

Select exactly two images: the photo with the subject first, then the replacement background. The subject is cut out automatically and drawn on top of the background, and the combined image is saved as a PNG.

### What size will the final image be?

The output keeps the dimensions of the subject photo. The background image is scaled up or down until it fills that frame and is centered, so parts of it may be cropped if its proportions differ.

### Why do the edges of my subject look rough?

Edges come from the model's segmentation, and hair, transparent objects and low-contrast outlines are the hardest cases. Review the edges at full size; a photo with clearer separation from its background may give a better cutout.
