CRW at a glance
CRW
Convert to CRW when maintaining compatibility with older Canon raw libraries or recovering historical camera originals.
In most current workflows it is a source to preserve or migrate, not a preferred new output format.
HTML at a glance
HTML
Convert to HTML when the output is meant to be read in a browser, indexed by search engines, linked from other pages, or embedded in a web application.
It is a strong target for documentation, knowledge-base content, public reports, landing pages, and long-form articles that need responsive display and hyperlinkable sections.
Use HTML when accessibility, discoverability, and browser delivery matter more than preserving an exact print layout.
It is also useful as an intermediate format for content pipelines that later restyle or templatize the output.
