Mark as safe HTML: safe

The safe filter marks a string as safe HTML, which means it will not be automatically escaped when rendered in an HTML context. Without this filter, HTML characters like < and > would be converted to their entity equivalents to prevent accidental HTML injection. This is useful when you intentionally want to include HTML markup in your output. For example, you might want to include bold text, links, or line breaks in a Markdown card or an HTML notification message. Use this filter with care and only on content you trust, since it bypasses the automatic escaping that protects against malformed or unexpected HTML.

Usage

Function signature

The signature is a technical summary of this template function. It shows the name of the function, the values (called parameters) it accepts, and what type of data each parameter expects (for example, a piece of text or a number).

Function parameters that have a = with a value after them are optional. If you leave them out, the default value shown is used automatically. Function parameters without a default are required.

Good to know

  • Only apply this to content you trust. Untrusted input marked safe can inject HTML.
  • Use forceescape downstream to re-escape a value that was marked safe.
