AI cut-out
On photos, AI can find people, pets and objects. For videos and the live camera, it separates people from the background. Cut-outs are processed on your iPhone with Apple’s Vision framework.
Live camera
Choose a background and record with sound in real time. Switch between the front and back cameras, take a photo or use a 3-second or 10-second timer.



Export
Export MP4 with the original sound, transparent PNG or JPEG. Pro adds video up to 4K, transparent HEVC with alpha, ProRes 4444 and animated GIF. A photo on an animated background can become a video or GIF.
Your projects
Move, resize and rotate the subject. Match brightness, contrast, saturation and warmth, then add a shadow or sticker outline. Use vertical, square or wide canvases, and return to saved projects from the home screen.
Choose a yearly subscription with a free trial, a weekly subscription or a one-time lifetime purchase. Prices and trial details are shown in the app before you buy.
Free
Free exports include a small Chromo badge. Videos and live recordings are limited to 15 seconds, and photos to 2048 px.
Chromo Pro
Remove the badge, export full-length videos up to 4K and full-resolution photos, and unlock transparent video, GIF, all 37 backgrounds and video backgrounds.

Chromo processes your edits on your iPhone and does not upload your photos or videos. If you choose Apple’s Image Playground to create a background, Apple handles that request under its own privacy policy.
Chromo requires iOS 17 or later. Automatic cut-out results depend on your footage, so check the finished export before publishing it.
