How to use this tool
Choose a photo and an output image format, then download the grayscale version.
Before you begin
Grayscale conversion changes colors and may re-encode the image. Files remain on your device.
Why keep files local?
The tool reads the input with your browser and processes it on your device. It does not send your file to a Workpico conversion API. If you share a result by copying or downloading it, you control what happens next.
