Privacy & metadata

Everything runs in your browser on a canvas — your image is never uploaded. Browser canvas export strips EXIF, GPS, and most other source metadata.

Black and White Image Converter in your browser

Black and White Image Converter converts a photo to black and white (greyscale) on a browser canvas. Everything runs in your browser on a canvas — your image is never uploaded. Choose your output format: PNG and WebP can preserve transparency only when the source has an alpha channel and Background is set to Transparent, while JPG flattens transparent areas onto the selected background colour.

Greyscale removes colour while keeping tonal detail. Because JPG cannot store transparency, transparent areas are filled with your chosen background colour for JPG output; PNG and WebP can preserve transparency when the source has an alpha channel and Background is set to Transparent.

Black and White Image Converter shows the output dimensions, the output format, and whether transparency was kept or filled. Browser canvas export strips EXIF, GPS, and most other source metadata. Animated GIFs are processed as a single still frame; animation is not preserved.
