T2T to DocBook Converter
Processing entirely on your device — large files may take a moment.
txt2tags and DocBook XML exist for different jobs: 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 DocBook when XML source needs to become Word manuscripts, Markdown docs or web pages.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.
How T2T compares to DocBook
| T2T | DocBook | |
|---|---|---|
| Structure | Plain-text lightweight markup | Semantic XML (<chapter>/<section>/<para>) |
| Compatibility | txt2tags compilers | XSL-FO, Pandoc, docbook-xsl |
| Best for | Legacy lightweight docs | Books, manuals, enterprise documentation |

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- −Tooling is no longer maintained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 DocBook format
DocBook is the XML schema that industrial technical publishing was built on. Instead of markup for appearance, it marks meaning: <chapter>, <section>, <para>, <figure>, <indexterm>. A single DocBook source renders to PDF via FO processors, HTML help systems, EPUB and printed books — O'Reilly, Red Hat and virtually every enterprise manual pipeline relied on it, and the man pages on your Linux box descend from the same lineage.
DocBook's rigor is its weight: authoring by hand is verbose, and moving content into lighter systems is a standing chore. Pandoc reads the element structure directly, so a book chapter becomes a Word manuscript or a Markdown docs page with sections, tables and code blocks intact — single-sourcing out, editing comfort in.
+Strengths
- ✓Semantic, presentation-free source of truth
- ✓One source renders to print, web and EPUB
- ✓Decades of enterprise tooling
!Limitations
- −Verbose XML — painful to hand-edit
- −Heavy processor toolchain (XSL-FO)
- −Overkill for anything shorter than a manual

Frequently asked questions
Is this T2T to DocBook 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 DocBook?
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.
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.
Can I edit the DocBook result afterwards?
That depends on the target: DocBook is designed for what it does, and this converter reproduces its content faithfully rather than inventing editable structure. For heavy re-editing, work from a format built for editing and export the final version here.
