Frequently Asked Questions
How does the black and white conversion work?
The converter uses a luminance formula (0.299*R + 0.587*G + 0.114*B) to convert color images to grayscale. This preserves the perceived brightness of different colors, creating natural black and white images.
What image formats are supported?
The Black & White Converter supports JPG, PNG, WebP, and GIF formats. The output is always PNG to preserve quality and support transparency if present.
What is the sepia effect?
Sepia tone gives images a warm, brown-toned vintage appearance. It applies a color transformation that mimics aged photographs from the early days of photography.
How do the contrast and brightness sliders work?
The contrast slider ranges from -100 to +100, enhancing or reducing the difference between light and dark areas. The brightness slider adjusts the overall lightness of the image. Both update in real-time as you adjust them.
Is my image data private?
Absolutely. All conversion happens in your browser. Your images never get uploaded to any server, ensuring complete privacy and security.
