## Description

Restore missed subject areas, then create 1:1, 4:5, and 9:16 share-ready images in one tap. Processing stays entirely on device.

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

Product images
· Apply a white background, square canvas, composition, edge treatment, and shadow in one tap
· Original size or 800×800, 1000×1000, 1200×1200, and 1600×1600 squares
· Adjust subject size, placement, background colour, and shadow

Batch processing
· Select up to nine photos
· Apply one background, size, format, placement, and shadow to the batch
· Stop and resume any time, retry only failed items
· Share every finished image at once

More tools
· Stitch Screenshots reduces repeated fixed headers and footers
· Film Negative restores colour or black-and-white negatives with manual colour controls

Save and share
· Original-size export keeps the photo's full native pixels
· PNG preserves transparency
· JPG fills an effective background
· Save to Photos or use the system share sheet

Privacy
Koutuxia has no account, ads, cloud upload, or data collection. Apple frameworks process every image on your device.
