About the Image to Grayscale
Turn color images into grayscale for print, a classic black-and-white look or accessibility checks. The conversion uses Rec. 709 luminance weights (21% red, 72% green, 7% blue), which match how bright colors appear to the human eye better than a simple average.
Lower the strength slider for a muted, partially desaturated look.
How to use it
- Set the strength (100% for full black and white).
- Choose the output format.
- Drop images and download the grayscale versions.
Good to know
- The output is still saved as an RGB image with equal channels, which every app can open.
- For grayscale PDFs use the PDF Grayscale tool.
