Fast, secure OPML to ORG conversion. No registration required.
Setup: OPML is a document format oriented around a particular office suite or publishing pipeline. Goal: an interchangeable ORG. If you are staring at a OPML and need a clean ORG, retyping is never the answer — our converter routes the file through LibreOffice in headless mode and pandoc for text formats, which is the same pair of tools professional publishers rely on. Styles, tables, bullets and images all make it across. Context: OPML is a document format oriented around a particular office suite or publishing pipeline. ORG 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.
Org-mode
Target formatOrg-mode is a markup language and organizational system created for GNU Emacs. It combines document authoring with task management, literate programming, and reproducible research in a plain text format with a powerful outlining structure.
Why convert OPML to ORG
OPML and ORG both describe paginated text, but they target different parts of the document life cycle. OPML is usually editable; ORG is usually final. Converting is about moving from editing to distribution (or the other way round) without losing headings, styles, tables or embedded images along the way.
HOW TO CONVERT
OPML → ORG
Upload your OPML
Drop the document onto the uploader. We transfer over HTTPS and keep the file in an isolated processing container.
Render with LibreOffice
LibreOffice opens the OPML headlessly and writes it as ORG with styles, tables and images mapped across.
Download the ORG
The ORG is ready to download; typography, pagination and embedded assets match what you saw in the source.
Common Use Cases
Share across platforms
Send ORG files to anyone without worrying about whether they have the right software for OPML.
Embed in documents
Drop ORG output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
ORG 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 ORG — 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.
ORG Strengths
- All-in-one productivity format — tasks, notes, agenda, papers.
- Plain UTF-8 text — diff-friendly, version-controllable.
- Literate programming with tangle/weave.
- Exports to HTML, PDF, LaTeX, ODT, Markdown, Beamer.
- Active open-source community with decades of extensions.
Limitations
- Emacs-centric — full power requires Emacs; other editors see syntax but miss features.
- Steep learning curve alongside Emacs itself.
- Limited mobile support (Orgzly on Android is the main option).

Quality & Compatibility
LibreOffice handles the heavy lifting and maps the overwhelming majority of OPML features to their ORG equivalents. Standard system fonts (Arial, Calibri, Times, Helvetica) transfer exactly; corporate or custom fonts are substituted with the closest available match, which can shift line breaks by a character or two. Inline images embed at original resolution.
Tips for Best Results
- Embed fonts in the OPML before uploading if you use non-system fonts — it guarantees the ORG renders identically on any viewer.
- Check tables, figure captions and page headers after conversion; complex layouts occasionally need a minor nudge in the target application.
- For documents with a table of contents, refresh the TOC field after opening the ORG so page numbers reflect the new pagination.
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 ORG at full resolution, editable tables become native ORG tables, and hyperlinks keep their URLs. Complex features unique to OPML — macros, form fields, track-changes — are mapped where an equivalent exists in ORG 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.
