Ghostscript + QPDFHOW TO CONVERT OPML → MAN
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 MAN with styles, tables and images mapped across.
Download the MAN
The MAN is ready to download; typography, pagination and embedded assets match what you saw in the source.
Setup: OPML is a document format oriented around a particular office suite or publishing pipeline. Goal: an interchangeable MAN. If you are staring at a OPML and need a clean MAN, 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. Background. OPML is a document format oriented around a particular office suite or publishing pipeline. Destination side, MAN is a document format oriented around a particular office suite or publishing pipeline.
Why convert OPML to MAN
OPML and MAN both describe paginated text, but they target different parts of the document life cycle. OPML is usually editable; MAN 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.

OPML vs MAN — 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.
MAN Strengths
- Universal Unix-like OS documentation since 1971.
- Plain text with simple troff markup — tiny files.
- Section system cleanly separates commands from APIs from config files.
- Renders to terminal, PostScript, HTML, or PDF.
- Every Unix programmer knows the format.
Limitations
- Terse by design — bad for tutorials or beginner-friendly intros.
- Troff syntax is arcane and difficult for modern authors.
- No interactive examples or live-editable snippets.
Quality & Compatibility
LibreOffice handles the heavy lifting and maps the overwhelming majority of OPML features to their MAN 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 MAN 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 MAN 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 MAN at full resolution, editable tables become native MAN tables, and hyperlinks keep their URLs. Complex features unique to OPML — macros, form fields, track-changes — are mapped where an equivalent exists in MAN 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.
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.
Unix Man Page
Target formatMan (manual) pages are the standard documentation format for Unix and Linux command-line tools, written in troff/groff markup. They follow a structured layout with NAME, SYNOPSIS, DESCRIPTION, and OPTIONS sections for consistent reference.

Common Use Cases
Share across platforms
Send MAN files to anyone without worrying about whether they have the right software for OPML.
Embed in documents
Drop MAN output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
MAN 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 MAN — Typical file sizes
Approximate file sizes for common scenarios.
- Typical RSS reader export (50 feeds) 5-30 KB
- Deep outline (Scrivener novel plan) 20-200 KB
- Single command man page 2-15 KB
- Complex tool (e.g., bash man) 80-200 KB
