Koutuxia: Background Remover

Koutuxia is an on-device background remover and product-photo editor for iPhone and iPad. Choose a photo, separate its subjects, then adjust the background, canvas, composition, edges, and shadow. No account or upload is required, and it works in Airplane Mode.

Remove backgrounds
· Choose from Photos, import from Files, or paste from the clipboard
· Send an image straight from the Photos or Files share sheet
· Detect people, pets, products, and everyday objects
· Keep one, several, or all detected subjects
· Export a transparent background for further design work

Edge cleanup
· Smart mode removes colour fringes and keeps soft hair detail
· Full-resolution export aligns the mask with real edges in the original photo
· Hair & Fur preserves the mask exactly as detected
· Product Edge applies stronger cleanup to common background fringes
· Inspect edges full screen with pinch-to-zoom

Fix background
· When detection misses the subject or leaves background behind, tap the area to clear it
· Tap two separated same-colour areas to clear that colour everywhere
· Brush anything back later with the refine editor

Refine precisely
· A live magnifier follows the brush
· A coloured mask overlay helps with erasing and restoring
· Pinch to zoom and drag the canvas
· Strokes are final; restore automatic edges at any time
· Undo, redo, or reset changes
