What is Green Screen (Chroma Key)?

Green screen (chroma key) is a technique where a specific color (usually bright green) is made transparent, allowing you to replace the background with another image or color. Our tool detects green pixels and removes them, leaving the foreground subject. You can adjust tolerance to control how much green is removed. Then replace with a solid color or upload a custom background image. Perfect for creating YouTube thumbnails, product photos, or fun edits. All processing is local – your images stay private.

📌 How to Use

Upload an image with a green background.
Adjust tolerance (higher = more green removed).
Choose a replacement background color or upload an image.
Click "Remove Green Screen".
Download the result as PNG.

⚙️ How It Works

We analyze each pixel's RGB values. If the pixel is close to green (within tolerance), we make it transparent (or replace with new background). The foreground is kept.
