Markdown is a text-to-HTML conversion tool for web writers. Markdown allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid HTML.

Sketchfab supports Markdown in model descriptions and Annotations.

Primary Markdown Syntax

These are the features most relevant to Sketchfab models: Images, Links, Videos, Text emphasis, Text titles, Lists.

Images

![](https://website.com/path/to/img.jpg)

Optionally, you can add alt text and a title (important for SEO and accessibility), like this:

![Alt text](https://website.com/path/to/img.jpg "Title")

Links

This is [an example](http://example.com/ "Title") inline link.[This link](http://example.net/) has no title attribute.This is [an example][id] reference-style link.Other stuff goes here...[id]: http://example.com/  "Optional Title Here"

You can make an image that is a link by combining the link code with the image code. Use the image code instead of text:

[![](https://website.com/path/to/img.jpg)](http://example.com)

Videos

While you can link to a video hosted elsewhere (as described above), you cannot produce a video within your model's description or Annotations by using Markdown.

If you'd like to build a more customized experience with features like embedded videos, it's possible to do on your own website using the Viewer API.
