The Code/Markdown application in CryptPad is an integration of CodeMirror.

The Code application is particularly suited for writing documents in Markdown: a lightweight syntax that offers basic formatting while remaining readable. Markdown is readily converted to other formats such as HTML.

Markdown syntax guide.

Additionally to basic Markdown syntax, the following features are also available:

  • [TOC] Inserts a table of contents.

  • Todo list

    • - [ ] task for a task to do: task.

    • - [x] task for a completed task: task.

  • Diagrams with Mermaid.

  • Mindmaps with Markmap.

  • Mathematical equations with Mathjax.


It is strongly advised not to insert external images in documents. The Markdown syntax ![description]( is supported but presents security risks. Malicious code can be hidden in images and result in data leakage.

For this reason, CryptPad makes use of media-tag to insert images from the CryptDrive. This syntax is more complex but it is managed automatically by the Insert menu.
