Chroma Key - Green Screen PNG

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.

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.
