Frequently Asked Questions
How do I convert a color photo to black and white?
Simply upload your photo and it will be automatically converted to grayscale. No settings needed — the conversion happens instantly in your browser.
What is the difference between grayscale and black and white?
Grayscale images use shades of gray between black and white, preserving tonal detail. This tool converts to true grayscale, not a high-contrast two-tone effect.
Can I use this for printing?
Yes. The grayscale output is saved as a PNG file at the original resolution, making it suitable for printing or digital use.
Does the conversion preserve image details?
Yes. The grayscale conversion uses luminance-weighted values that preserve the perceived detail and contrast of the original color image.
