OPML to DOTM Converter
Processing entirely on your device — large files may take a moment.
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 DOTM templates to PDF or extract their text like any Word file.
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.

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 DOTM format
DOCX is the modern Microsoft Word format (Office Open XML, default since Word 2007). A file is actually a ZIP package of XML parts — document body, styles, numbering, headers, embedded media — which is what lets Word, Google Docs, LibreOffice, WPS and Pages all open it natively. Text flows around styles rather than absolute positions, so a document adapts to the page it is rendered on.
It is the format of collaboration: tracked changes, comments, styles and templates are first-class citizens, and office ecosystems assume it. The trade-off is layout drift — the same DOCX paginates slightly differently across renderers, and very complex layouts (exact positioning, text over images) can shift. For contracts in progress it is ideal; for the signed final, export a PDF.
+ Strengths
- ✓Fully editable with styles, track changes and comments
- ✓Opens natively in Word, Google Docs, WPS, LibreOffice
- ✓Flowing layout adapts to any page size
! Limitations
- −Pagination and layout shift between renderers
- −Complex layouts may not survive round-trips
- −Not suitable as a final, fixed distribution format

Frequently asked questions
Is this OPML to DOTM 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.

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 DOTM?
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.

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.
Will the layout of my OPML file be preserved exactly?
This converter renders your OPML content into DOTM 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.
