WebM Grayscale

Convert WebM to black and white in your browser. Optional MP4 for universal playback.

WebM is common for screen capture and HTML5. Grayscale gives a monochrome version without re-capturing. Export WebM or MP4 depending on audience.

When to use WebM Grayscale vs other formats

Choose WebM-focused grayscale for VP8/VP9 assets. For mixed devices, MP4 after processing is often simplest.

Example use cases
