About this plugin
Bibcit Any2HTML adds a powerful conversion panel to the WordPress post editor. Whether you’re working with Markdown text, technical diagram code, or document files (PDF/image), the plugin converts your content to clean HTML and inserts it straight into your post — no copy-pasting, no switching tools.
Key Features
Markdown to HTML
Paste any Markdown content into the editor panel and convert it to HTML in one click. Works with headings, lists, tables, code blocks, and all standard Markdown syntax.
Diagram Code to HTML
Convert diagram source code to rendered HTML diagrams directly inside the post editor. Supports a wide range of diagram languages across four categories:
- UML & Software Architecture — PlantUML, C4 PlantUML, Mermaid, Nomnoml, DBML, Structurizr, UMLet
- Graphs & Networks — Graphviz, D2, ERD, SMILES
- Block & Flow Diagrams — BlockDiag, ActDiag, NwDiag, PacketDiag, RackDiag, SeqDiag, BPMN, Ditaa, Pikchr

Select your diagram type from the dropdown, paste your code, and click Convert to HTML.
File Upload (PDF & Images)
Upload a PDF or image file (JPG, PNG — up to 5 MB) and the plugin will extract the content and convert it to HTML automatically.
Editor Compatibility
Works seamlessly with the Classic Editor, Gutenberg (block editor), and TinyMCE. Converted HTML is inserted at the cursor position.
API Key Management
Enter your Bibcit API key in the settings page and validate it with a single click. The conversion panel only appears once a valid key is confirmed. If a key becomes unauthorized during use, the plugin flags it immediately with a direct link to re-validate.
The full source code is publicly available on GitHub.
