## What is Chroma Key?

Remove a green, blue, or other solid-color background from a photo and export a PNG with real transparency.
Tap the key color, refine the edge, and save at the source image's pixel dimensions.
No ads, watermark, subscription, account, or server upload.

Key features

• Automatic key-color estimate, eyedropper, and green or blue presets
• Tolerance, edge softness, and color-spill adjustment
• Erase and restore brushes with up to 60 undo or redo steps
• Checkerboard, white, and black transparency previews
• Import from Photos, Files, or iCloud Drive
• Save to Photos, share a PNG file, or copy the PNG

How it works

1. Choose a photo or image file
2. Tap the background color and adjust the result
3. Export a PNG with an alpha channel

Built for green screen photos, product shots, illustrations, and other images with a solid-color background. This is a chroma key tool: it removes pixels based on a color you choose rather than using AI subject detection.

One purchase unlocks every feature. There are no subscriptions, in-app purchases, ads, watermarks, or usage limits.
