Frequently Asked Questions
Grayscale converts each pixel to a shade of gray based on its luminance —you get the full tonal range from pure black to pure white with all the gray shades in between. Black & White mode applies a threshold: pixels brighter than the threshold become pure white, and darker pixels become pure black. B&W is better for text, documents, and graphic art; Grayscale is better for photos.
Visually yes —the shapes, edges, and tones are all preserved. Only the color information is removed. The image will look like a classic black-and-white photo.
Yes. Set the Intensity slider below 100% to blend between the original color and full grayscale. At 50%, the image will appear muted/faded. This is useful for vintage effects or subtle toning.
JPEG is recommended for photos —it produces smaller files. PNG is better when you need lossless output (e.g., for logos or documents where sharp edges matter).
