Is Grayscale Image free to use?

Yes, completely free. No signup, no watermark, no file limit.

Is Grayscale Image safe? Do my files get uploaded?

No upload required. All conversion happens in your browser using the Canvas API. Your images never leave your device.

Does Grayscale Image work on mobile, iPhone, and Android?

Yes. It works in any modern browser including Safari on iPhone and Chrome on Android.

Will the file size be smaller after converting to grayscale?

Sometimes. For JPG, the file size may be slightly smaller because the chroma channels carry less variation. For PNG, the difference is usually minimal unless you also convert to a grayscale-only PNG format.

Can I get a true black-and-white image instead of grayscale?

This tool converts to grayscale (256 shades of gray). For a pure two-tone black-and-white look (no gray midtones), adjust the contrast using our Brightness & Contrast tool after grayscaling.
