## Description
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
* Technical & Specialized — WaveDrom, Bytefield, SVGBob, TikZ, Symbolator, WireViz
* Data & Mind Visualization – Vega, Vega-Lite, Excalidraw, Markmap
* Vector Graphics- SVG
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](https://github.com/bibcit/any2html).
### Requirements
* A Bibcit account and API key — sign up at bibcit.com.
* An active internet connection (required for API communication).
### Third-Party Service
This plugin connects to the Bibcit API (api.bibcit.com), an external service operated
by Bibcit.
**Data transmitted:** Your Markdown text, diagram code, or uploaded file (PDF/image)
is sent to the Bibcit API solely for conversion. Your API key is included as a request
header (Bibcit-Key) for authentication.
**When it is sent:** Only when you click “Convert to HTML”, and only when the plugin
is active with a valid API key.
**Privacy:** Content is processed in real-time and is not stored, logged, or retained—
ensuring full privacy of your post content.
