OPML to LaTeX Converter
Processing entirely on your device — large files may take a moment.
Outline Processor Markup and LaTeX Source exist for different jobs: OPML is the outline-exchange XML: nested <outline> elements that carry subscription lists (podcast apps, RSS readers) and mind-map exports from Workflowy, Dynalist and OmniOutliner. Convert LaTeX exactly like TEX: into Word, EPUB, HTML or Markdown.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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
About the LaTeX format
LaTeX is how academia writes: preprints, theses, journal submissions and most of arXiv and Springer's back-catalogue are LaTeX sources. A .tex file is plain text with markup commands — \\section{…}, $math$, \\cite{…} — that a compiler turns into perfectly typeset PDF with numbered equations, cross-references and bibliographies.
Converting into LaTeX is the boring 80% of the academic workflow: your Markdown notes, Word draft or EPUB becomes a .tex skeleton with proper sectioning and math, ready to paste into the journal's template. The output here is source, not a compiled PDF — the final typesetting happens in the journal's or arXiv's own compiler.
+Strengths
- ✓The required format for arXiv and most journals
- ✓Math, cross-references and citations as first-class citizens
- ✓Plain text — version-controllable and diff-able
!Limitations
- −Not directly viewable — needs a LaTeX compiler
- −Steep learning curve for manual editing
- −Complex layouts may need template tweaks

Frequently asked questions
Is this OPML to LaTeX 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 OPML to LaTeX?
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 LaTeX result afterwards?
That depends on the target: LaTeX 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.
