Why this pair exists — MD is Markdown, a plain-text format with minimal syntax that renders to formatted HTML. Ergo, the OPML route. A MD to OPML job turns one office document into another without retyping anything. Styles, pagination and embedded content cross the bridge cleanly because we use the same engine that powers professional document pipelines. Upload a MD file above, adjust any Advanced options, and download a ready-to-use OPML. Technical note: MD is Markdown, a plain-text format with minimal syntax that renders to formatted HTML. Compare that with OPML is a document format oriented around a particular office suite or publishing pipeline.
Markdown
Source formatMarkdown is a lightweight markup language that uses plain text formatting syntax. It is widely used in software development, technical documentation, and content management systems.
OPML Outline
Target formatOPML (Outline Processor Markup Language) is an XML format for structured outlines and lists. It is most widely used for exchanging RSS feed subscription lists between podcast apps and feed readers, and for hierarchical note-taking.
Why convert MD to OPML
Opening MD in the tool that natively reads OPML is rarely clean. Converting upstream rebuilds the document in the target format so headings become headings, lists stay lists, and the receiving tool does not flag layout warnings.
HOW TO CONVERT
MD → OPML
Drop the MD file
Upload your document — or a ZIP of several documents for batch conversion — through the web form.
Convert through pandoc
Our pandoc-based pipeline opens the MD, preserves structure and typography, and writes the OPML.
Retrieve the document
Click the download button; the OPML is delivered as a single file (or ZIP of files for batch jobs).
Common Use Cases
Email distribution
Office recipients open OPML in their default reader; MD may arrive with a missing-font warning or layout shift.
Signing and notarisation
OPML is the standard format for DocuSign, Adobe Sign and notary workflows; MD usually needs converting first.
Contract handoff
Legal teams exchange contracts as OPML because it preserves formatting and supports digital signatures out of the box.
Form distribution
Fillable forms — tax documents, applications, surveys — live in OPML and work on any platform that reads the format.
Quality & Compatibility
Headings, paragraphs, lists, tables, hyperlinks and inline images all survive the conversion with their semantic structure intact. Rare features unique to MD — legacy macros, form fields, obscure frame styles — are flattened to static content where no direct OPML equivalent exists. Tracked changes, where both formats support them, transfer cleanly.
Tips for Best Results
- Round-tripping between MD and OPML (converting back and forth) can accumulate small formatting drift — do one conversion and stay in that format.
- If the MD has tracked changes, accept or reject them before converting to avoid surprises in the OPML output.
- Very long documents split cleanly at existing section breaks; add section breaks deliberately if you need precise page boundaries.
Frequently Asked Questions
Frequently Asked Questions
Yes, as long as the fonts are standard (system fonts or common office fonts like Arial, Calibri, Times, Helvetica). Custom corporate fonts survive if they are embedded in the source document; otherwise the conversion substitutes the closest available match, which can shift line breaks by a character or two.
Yes. Inline images are embedded into the OPML at full resolution, editable tables become native OPML tables, and hyperlinks keep their URLs. Complex features unique to MD — macros, form fields, track-changes — are mapped where an equivalent exists in OPML and flattened into static content otherwise.
All uploads go over TLS, files are processed in isolated containers and both the source and the output are deleted within two hours. No account is required, file contents are never indexed or used for training, and the paid plan adds a signable data-processing agreement for regulated workflows.
