Koutuxia for iPhone

Pick a photo, cut out the subject, swap the background color, save it back to Photos — all on your iPhone. Nothing uploads, nothing connects: it works in Airplane Mode.

Get it on the App Store

Free · No account · No ads · Requires iOS 17 or later

On the App Store in the US, Japan, Hong Kong, Taiwan and most other regions; not available in the mainland China store. The current release ships a Chinese interface — an English one is in review.

Koutuxia on iPhone: a black dog cut out against a transparent checkerboard, with background color swatches and a save button below

What the app does

It all happens on the phone: The cutout runs on Apple's own on-device vision framework. The app contains no networking code at all, and its App Store privacy label reads “Data Not Collected”. Your photo never leaves the device.
Background color in one tap: Transparent, white, black, red or blue. Enough for clean product shots and solid-color avatars.
Straight back into Photos: What you save is a transparent PNG with clean edges, ready for the next app — or send it out through the system share sheet.
No account, no quota: Open it and go. No sign-up, no ads, no counting. The compute is your phone's, so cutouts cost nothing.

No iPhone?

The web version works right now, and free cutouts run in your own browser — images stay put.
