When to use Grayscale image
Make a monochrome photo while retaining image dimensions. Choose PNG for transparent sources. This creates continuous gray tones rather than a two-color threshold effect.
Supported formats and limits
Image → JPG / PNG / WebP. This produces continuous grayscale, not a two-color threshold image. Metadata and animation are not preserved.
About this tool
Will grayscale make a strict black-and-white mask?
No. It produces continuous gray tones. It is not a two-color threshold tool or a background remover.
Can a transparent logo stay transparent?
Choose PNG or WebP. JPG fills transparent pixels white. Inspect the actual output format before downloading.
What should I inspect before sharing the grayscale image output?
This produces continuous grayscale, not a two-color threshold image. Metadata and animation are not preserved. Download the output and open it in the receiving application. A browser download request does not confirm that saving finished.
