About the Grayscale Tool
Our online grayscale converter removes color from any photo while preserving its full range of light and dark tones. It is ideal for classic black-and-white style portraits, print-ready images, or simply removing distracting colors.
Upload your image, select Grayscale from the color options, and preview the result before downloading. You can add more photos and apply the same conversion to an entire batch at once.
Everything runs locally in your browser, so your images are never uploaded to a server and stay completely private. There is no software to install, no account needed, and it is free with no limits.

Questions & Answers
-
How long does it take to convert an image to grayscale?Converting an image takes just a second or two in most cases, since everything runs locally in your browser's JavaScript engine rather than being sent to a server. Larger files or a full batch of images may take a little longer, but you'll see progress update live as each one finishes.
-
Is it safe to convert my photos here?Yes. Your images are processed entirely on your own device using your browser's built-in canvas and Web Worker features, and they are never uploaded to a server or stored anywhere online. Once you close or refresh the page, nothing about your photos remains on our side.
-
What browser should I use?Any modern browser works well, including Chrome, Firefox, Edge, and Safari on both desktop and mobile devices. The tool relies only on standard, widely supported browser features, so there is nothing extra to install, enable, or configure.
-
Does grayscale just remove the color, or does it change anything else?Grayscale only removes hue and saturation information from an image, converting each pixel's brightness into a matching shade of gray. The dimensions, transparency, and overall tonal range of the photo stay exactly the same.
-
What is the difference between grayscale and black and white?Grayscale keeps a full range of gray tones from black to white, similar to a classic gray-toned photograph. Black and white instead uses dithering to reduce the image to just pure black and white pixels, creating a bold, high-contrast look.
