Quick Answer

Local edits work best when you explicitly lock identity, pose, background, and framing, then change only one attribute. Use "ONLY CHANGE" prompts and keep each edit single-objective. Create a free account for 3 free credits - account required.

How It Works

1

Start with a clean input image.

2

Lock what must not change (identity, background, framing).

3

Change only one target: outfit OR background OR object.

Prompt Recipes

Copy a recipe, replace the [brackets] with your specifics, and generate.

Recipe 1 - Outfit swap only

Replace clothing while keeping person and background perfectly intact.

CRITICAL: Keep the person and background EXACTLY the same. ONLY CHANGE: replace clothing with [new outfit]. Seamless edges, realistic folds, match original lighting.

Recipe 2 - Remove an object

Remove something from the image and reconstruct the background naturally.

Keep everything unchanged. Remove the [object] and reconstruct the background naturally. No artifacts, clean texture.

Recipe 3 - Background tweak (small change)

Make a minor adjustment to the background without affecting the subject.

Keep subject unchanged. ONLY CHANGE: adjust background to [small change], keep perspective and lighting consistent.

Common Issues & Quick Fixes

Model changes multiple things at once

Fix: Rewrite prompt: "ONLY CHANGE: ... (one item only)"

Skin becomes plastic or unrealistic

Fix: Add "natural skin texture, no beauty retouch"

Edges look messy or have halos

Fix: Add "no halos, preserve fine hair strands, clean edges"

Frequently Asked Questions

Use "ONLY CHANGE" prompts with a single objective. Lock everything you want to keep with explicit constraints like "EXACT same face" and "Keep background unchanged."

The model may interpret your prompt broadly. Add "Keep background EXACTLY the same" or "DO NOT modify background" to prevent this.

Yes! Use strong identity constraints: "CRITICAL: Keep the same face, hair, skin tone, expression" combined with "ONLY CHANGE: clothing."
