# Import & Export
Trilium natively supports the following formats for both import and export.

*   HTML:
    *   This is the main format used by Trilium, where standard tags are used to represent basic formatting and layout (e.g. `<strong>`, `<table>`, `<pre>`).
    *   Note that HTML is not a standardized format so some more specific features such as admonitions or <a class="reference-link" href="../Note%20Types/Text/Links/Internal%20(reference)%20links.md">Internal (reference) links</a> might not be supported by other applications.
*   <a class="reference-link" href="Import%20%26%20Export/Markdown.md">Markdown</a>
    *   Most of the formatting is preserved, see <a class="reference-link" href="Import%20%26%20Export/Markdown/Supported%20syntax.md">Supported syntax</a>.
*   OPML (Outliner Interchange Format)
    *   Supports both OPML v1.0 for plain text and v2.0 with HTML support.
