In the experimental Document-Policy HTTP header, "bpp" does seem to signify bytes per pixel. Document-Policy explainer: https://github.com/wicg/document-policy/blob/main/document-policy-explainer.md https://github.com/wicg/document-policy/blob/main/document-p... I tried it out on my own site, and through trial-and-error I found that Chromium does in fact treat the "max-bpp" Document-Policy directives as bytes-per-pixel. I could be wrong; my memory has faded. Please correct me if this is the case.

I'm not sure what HTTP headers have to do with anything. Using "bpp" to mean bits per pixel is extremely common in image encoding. See e.g. https://en.wikipedia.org/wiki/Color_depth https://en.wikipedia.org/wiki/Color_depth where an uncompressed image is often 24 bpp (8 bits per channel). It's also common to use bitrate (rather than byterate) in audio encoding, see e.g. https://wiki.hydrogenaud.io/index.php?title=Bitrate https://wiki.hydrogenaud.io/index.php?title=Bitrate
