Ghostscript + QPDFHOW TO CONVERT ODT → OPML
Drop the ODT 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 ODT, 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).
Situation. ODT is the OpenDocument Text format, the native save format of LibreOffice and OpenOffice. Solution: a OPML, produced below. A ODT 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 ODT file above, adjust any Advanced options, and download a ready-to-use OPML. A quick refresher — ODT is the OpenDocument Text format, the native save format of LibreOffice and OpenOffice. By contrast, OPML is a document format oriented around a particular office suite or publishing pipeline.
Why convert ODT to OPML
Opening ODT 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.

ODT vs OPML — Strengths and limitations
What each format does best, and where it falls short.
ODT Strengths
- Truly open standard — ISO/IEC 26300, vendor-neutral.
- Native format of LibreOffice and OpenOffice, two of the largest FOSS projects.
- Human-readable XML, easy to script and parse.
- Preferred by many governments for archival and public records.
- ZIP compression keeps files compact.
Limitations
- Microsoft Word support exists but subtly breaks formatting when round-tripping.
- Less common outside the FOSS ecosystem — most business workflows default to DOCX.
- Fewer third-party tools than for DOCX.
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.
Quality & Compatibility
Headings, paragraphs, lists, tables, hyperlinks and inline images all survive the conversion with their semantic structure intact. Rare features unique to ODT — 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 ODT and OPML (converting back and forth) can accumulate small formatting drift — do one conversion and stay in that format.
- If the ODT 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
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 ODT — 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.
OpenDocument Text
Source formatODT is the open-standard document format used by LibreOffice Writer and other open-source word processors. It offers full document editing capabilities without vendor lock-in.
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.
Going the other way? Convert OPML back to ODT with the same engine.
Common Use Cases
Share across platforms
Send OPML files to anyone without worrying about whether they have the right software for ODT.
Embed in documents
Drop OPML output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
OPML often produces smaller files than ODT 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.
