Frequently Asked Questions

Does grayscale conversion change the image dimensions?▼
No. Only the color information is removed — the width, height, and resolution remain exactly the same.
What image formats are supported?▼
JPG, PNG, and WebP are all supported for input. The grayscale image is available for download in the same format.
Is grayscale the same as black and white?▼
Grayscale means the image uses only shades of gray (from pure black to pure white) with no color. This is what is commonly called black and white in photography.
Are my photos uploaded to a server?▼
No. The conversion uses the HTML Canvas API entirely in your browser. Your images never leave your device.
