Frequently asked questions

How to isolate the green channel of an image?
Select your file and the green channel is extracted automatically — red and blue channels are set to zero.
What is the green channel?
It represents the intensity of green light per pixel. Because human vision is most sensitive to green, it often closely resembles a grayscale image.
Why would I isolate the green channel?
For scientific analysis, artistic effects, or comparing how each color channel contributes to your image.
What file formats can I export?
You can export as PNG, JPEG, WebP, TIFF, BMP, or HEIC.
Is this tool free to use?
Yes — completely free, no account needed. Your images are processed entirely in your browser and never uploaded to a server. Downloads have no watermarks.
