About the Grayscale Image
Grayscale Image applies a luminance-weighted conversion so green contributes more perceived brightness than blue. Alpha transparency stays unchanged.
How to use the Grayscale Image
- Choose a color or existing monochrome image.
- Apply the grayscale pixel conversion.
- Compare contrast in the preview and download.
Practical tips
- Grayscale is useful for checking whether color-dependent content remains understandable.
- A monochrome effect does not automatically guarantee accessible contrast.
