Raster Web Image File Format
WebP is a modern raster image format developed by Google that supports both lossy and lossless compression. It delivers smaller file sizes than JPEG or PNG while maintaining comparable visual quality, speeding up web page loads. WebP also supports transparency (alpha channel) and animation, making it a versatile choice for websites and applications seeking efficient image delivery.

Questions & Answers
-
How long does it take to convert a WEBP image to black and white?Converting a WEBP image takes just a second or two in most cases, since everything runs locally in your browser's JavaScript engine rather than being sent to a server. Larger files or a full batch of images may take a little longer, but you'll see progress update live as each one finishes.
-
Is it safe to convert my photos here?Yes. Your images are processed entirely on your own device using your browser's built-in canvas and Web Worker features, and they are never uploaded to a server or stored anywhere online. Once you close or refresh the page, nothing about your photos remains on our side.
-
What browser should I use?Any modern browser works well, including Chrome, Firefox, Edge, and Safari on both desktop and mobile devices. The tool relies only on standard, widely supported browser features, so there is nothing extra to install, enable, or configure.
-
What is the difference between black and white and grayscale?Grayscale keeps a full range of gray tones from black to white, similar to an old gray-toned photograph. Black and white uses dithering to reduce a WEBP image to just pure black and white pixels, creating a bold, high-contrast, halftone-style look.
-
Will converting a WEBP image to black and white reduce its quality?The conversion does reduce color information by design, since that is exactly what a black and white effect is meant to do. Beyond that, no resampling or compression is applied, so the image dimensions and sharpness are fully preserved.
