Fast, secure OPML to MEDIAWIKI conversion. No registration required.
Setup: OPML is a document format oriented around a particular office suite or publishing pipeline. Goal: an interchangeable MEDIAWIKI. A OPML to MEDIAWIKI 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 OPML file above, adjust any Advanced options, and download a ready-to-use MEDIAWIKI. Worth knowing: OPML is a document format oriented around a particular office suite or publishing pipeline. Meanwhile MEDIAWIKI is a document format oriented around a particular office suite or publishing pipeline.
OPML Outline
Source 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.
MediaWiki Markup
Target formatMediaWiki markup is the wikitext syntax used by Wikipedia and thousands of MediaWiki-powered wikis. It provides formatting for links, tables, templates, categories, and references, powering one of the largest collaborative content systems.
Why convert OPML to MEDIAWIKI
Opening OPML in the tool that natively reads MEDIAWIKI 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
OPML → MEDIAWIKI
Drop the OPML 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 OPML, preserves structure and typography, and writes the MEDIAWIKI.
Retrieve the document
Click the download button; the MEDIAWIKI is delivered as a single file (or ZIP of files for batch jobs).
Common Use Cases
Share across platforms
Send MEDIAWIKI files to anyone without worrying about whether they have the right software for OPML.
Embed in documents
Drop MEDIAWIKI output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
MEDIAWIKI often produces smaller files than OPML for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
OPML vs MEDIAWIKI — Strengths and limitations
What each format does best, and where it falls short.
OPML Strengths
- Standard RSS subscription interchange format.
- Simple XML — easy to parse and generate.
- Highly extensible via arbitrary attributes.
- Supported by every major outline and RSS tool.
Limitations
- XML verbosity — larger than a JSON-based equivalent.
- Specification is loose — different tools disagree on edge cases.
- Primary use (RSS reading) has shrunk dramatically since Google Reader.
MEDIAWIKI Strengths
- Powers Wikipedia — battle-tested at planet scale.
- Templates enable reusable content blocks.
- Internal links, categories, and interwiki references work out of the box.
- Huge existing tooling and translation ecosystem.
Limitations
- Parsing is notoriously hard — context-sensitive by design.
- Authoring requires learning the unique syntax.
- Lacks standardization — no formal spec, just the MediaWiki implementation.

Quality & Compatibility
Headings, paragraphs, lists, tables, hyperlinks and inline images all survive the conversion with their semantic structure intact. Rare features unique to OPML — legacy macros, form fields, obscure frame styles — are flattened to static content where no direct MEDIAWIKI equivalent exists. Tracked changes, where both formats support them, transfer cleanly.
Tips for Best Results
- Round-tripping between OPML and MEDIAWIKI (converting back and forth) can accumulate small formatting drift — do one conversion and stay in that format.
- If the OPML has tracked changes, accept or reject them before converting to avoid surprises in the MEDIAWIKI output.
- Very long documents split cleanly at existing section breaks; add section breaks deliberately if you need precise page boundaries.
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 MEDIAWIKI at full resolution, editable tables become native MEDIAWIKI tables, and hyperlinks keep their URLs. Complex features unique to OPML — macros, form fields, track-changes — are mapped where an equivalent exists in MEDIAWIKI 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.
