T2T to OPML Converter
Processing entirely on your device — large files may take a moment.
txt2tags (T2T) is a minimalist markup that compiles one source into HTML, LaTeX, man, MoinMoin and more — the write-once-publish-anywhere idea a decade before static site generators. Convert OPML outlines into Markdown or Word documents, or turn bullet lists back into an importable outline.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the T2T format
txt2tags (T2T) is a minimalist markup that compiles one source file into HTML, LaTeX, man, MoinMoin, Wikipedia and more — the write-once-publish-anywhere idea implemented a decade before static site generators made it fashionable.
T2T installations are rare today, but documents written in it are still around. Converting T2T to Markdown moves that content into every modern tool.
+Strengths
- ✓Tiny learnable syntax
- ✓One source, many outputs by design
!Limitations
- −Tooling is no longer maintained
- −Niche user base
About the OPML format
OPML (Outline Processor Markup) is XML for hierarchies: nested <outline> elements, each with text and optional attributes. It is the silent standard behind podcast and RSS subscription lists — every "export subscriptions" button produces one — and the interchange format for outliners like Workflowy, Dynalist and OmniOutliner.
An outline is already half a document: Pandoc turns OPML hierarchies into Markdown headings, Word outlines or HTML pages with the nesting preserved, and can write OPML back out so a bulleted plan becomes an importable tree in your outliner of choice.
+Strengths
- ✓Universal outline exchange between outliners
- ✓The RSS/podcast subscription standard
- ✓Trivially parseable XML
!Limitations
- −Hierarchies only — no rich text per node
- −Attribute conventions vary between apps
- −Rarely rendered directly for humans
Why convert T2T to OPML?
There is a concrete reason this conversion exists: Tooling is no longer maintained OPML sidesteps that — Universal outline exchange between outliners If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this T2T to OPML converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for T2T to OPML?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Will the layout of my T2T file be preserved exactly?
This converter renders your T2T content into OPML with pages, proportions and images kept as close to the original as the target format allows. Use the preview before downloading to confirm it looks the way you expect.
Does the conversion work offline?
Yes. Once the page has loaded, the conversion itself runs entirely inside your browser — you can even disconnect and keep converting. No file ever touches a server.
