Frequently asked questions
- How to convert a photo to black and white?
- Select your file and it is converted to grayscale instantly using perceptual weights — no settings needed.
- How is grayscale conversion done?
- The tool blends R, G, and B channels using perceptual weights based on human vision sensitivity to produce a natural black-and-white image.
- Is this the same as converting to black and white in Photoshop or Lightroom?
- Similar — all use luminosity-weighted blending. Photoshop's Black & White adjustment layer adds per-channel sliders for more control; this tool applies a standard one-click perceptual conversion.
- What file formats can I export?
- You can export as PNG, JPEG, WebP, TIFF, BMP, or HEIC.
- Is this tool free to use?
- Yes — completely free, no account needed. Your images are processed entirely in your browser and never uploaded to a server. Downloads have no watermarks.
