HTML Entity Converter is one useful step. Explore related TanzaiTools categories to finish the broader task with less switching between websites.
Browse all toolsHTML Entity Converter offers two limited modes for the characters ampersand, less-than, greater-than and double quote. Encode mode replaces those characters with common entities; decode mode reverses the four supported forms. Use it for small HTML snippets when this exact set is sufficient. It is not a complete HTML entity parser, does not handle apostrophes in this combined route, numeric references or the full named-entity catalog, and repeated conversion can change already encoded text. Processing stays local.
