How to use Grayscale Image
- Choose a color picture.
- Compare the original with the automatically generated grayscale preview.
- Download the grayscale PNG.
A closer look
Grayscale replaces color with shades of gray while keeping the picture’s dimensions. The browser’s grayscale filter weights the color channels to maintain useful visual contrast rather than simply discarding two channels. Transparent areas remain transparent. This can make documents more consistent, create a monochrome image for a layout, or help you judge contrast independently of color.
A practical example
Make a color portrait monochrome for a document layout. The PNG keeps its dimensions and transparent areas while the visible colors become shades of gray.
A useful tip
Check that objects that were distinguished only by color are still easy to tell apart.
Good questions. Simple answers.
Can this restore color to a black-and-white picture?
No. It removes color information; it cannot recover colors that are not present.
Will the file necessarily get smaller?
No. The output is PNG and size depends on the source format and picture content.
