Technical Details of Grayscale Conversion

  • Luminosity Method: Our tool uses a common method for converting to grayscale, which averages the red, green, and blue values but weighs them differently to better approximate human perception of brightness (e.g., 0.299*R + 0.587*G + 0.114*B).
  • Client-Side Processing: All image manipulation occurs directly in your browser using JavaScript, ensuring privacy and speed as your images are never uploaded.
  • Output Format: The converted image will be downloaded in the same format as the original, or as PNG if the original format is not supported for direct download from canvas (e.g., some WebP conversions).
