Ghostscript + QPDFHOW TO CONVERT T2T → OPML
Drop the T2T 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 T2T, 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).
Here is the short version — T2T is a document format oriented around a particular office suite or publishing pipeline. Hence the need for OPML. A T2T 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 T2T file above, adjust any Advanced options, and download a ready-to-use OPML. Worth knowing: T2T is a document format oriented around a particular office suite or publishing pipeline. Meanwhile OPML is a document format oriented around a particular office suite or publishing pipeline.
Why convert T2T to OPML
Opening T2T 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.

T2T vs OPML — Strengths and limitations
What each format does best, and where it falls short.
T2T Strengths
- Plain-text source → multi-format output.
- Simple syntax.
- Tiny implementation.
Limitations
- Superseded by Pandoc.
- Tiny ecosystem.
- Limited modern tooling.
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 T2T — 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 T2T and OPML (converting back and forth) can accumulate small formatting drift — do one conversion and stay in that format.
- If the T2T 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 T2T — 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.
txt2tags
Source formattxt2tags is a minimal markup language that can be converted to many output formats including HTML, LaTeX, DocBook, and plain text. Its syntax is intentionally simple, using only ASCII characters for all formatting directives.
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 T2T 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 T2T.
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 T2T 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.
T2T vs OPML — Typical file sizes
Approximate file sizes for common scenarios.
- Short article source 2-20 KB
- Typical RSS reader export (50 feeds) 5-30 KB
- Deep outline (Scrivener novel plan) 20-200 KB
