About HTML Escape
HTML Escape encodes or decodes HTML special characters so they can be safely embedded in markup, data payloads, and code strings. Unescaped special characters in HTML can break document structure or introduce injection vulnerabilities — escaping them at the boundary ensures the content is treated as data rather than markup. Use it when inserting user-generated content into a template, preparing strings for use in attributes, or decoding escaped values you received from an external service.
Common uses
  • Escape special characters before embedding content in HTML templates, attributes, or data fields.
  • Prevent injection issues by properly escaping user-generated or third-party content at the boundary.
  • Unescape encoded strings to read their original content when inspecting logs or API responses.
  • Copy safe output directly into code, documentation snippets, or test fixtures.
