Convert images to grayscale
Click or drop an image here
Grayscale Converter turns a color image into black and white by averaging each pixel's red, green, and blue values, entirely in your browser. Your image is never uploaded to a server.
What image formats does Grayscale Converter support?
It accepts common formats your browser can open, such as JPG, PNG, and WebP. The output is always a PNG file.
Is there a file size limit for uploading images?
There's no fixed size limit — processing happens locally in your browser, so it's limited only by your device's available memory.
Will the tool reduce the quality of my image?
No, the original resolution is preserved — only the color information is changed.
Can I convert multiple images at once?
No, the tool converts one image at a time — there's no batch upload.
