Vimwiki to OPML Converter
Processing entirely on your device — large files may take a moment.
Vimwiki Markup and Outline Processor Markup exist for different jobs: Vimwiki is the personal-wiki markup of the Vim plugin of the same name: = headings =, [[links]] and {{images}} — a knowledge base living entirely in plain text inside Vim. Convert OPML outlines into Markdown or Word documents, or turn bullet lists back into an importable outline.
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 Vimwiki format
Vimwiki turns Vim into a personal wiki: files of plain text with = headings =, [[wiki links]], {{templates}} and :tags:, linked into a local knowledge base. Because everything is plain text, a Vimwiki vault survives editors, machines and decades — it is the format of people who think in keystrokes.
Leaving the vault is the moment conversion matters. Markdown-based tools like Obsidian and Logseq accept the content happily once Pandoc has remapped the syntax; HTML exports give the wiki a publishable face; Word documents satisfy the one compliance request a year.
+Strengths
- ✓Whole knowledge bases in plain text
- ✓Instant keyboard-driven navigation
- ✓Converts cleanly — grammar is small
!Limitations
- −Requires Vim fluency to edit comfortably
- −Dialect differs from standard Markdown
- −Link/image syntax needs remapping on export
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 Vimwiki to OPML?
Converting makes sense where the strengths of OPML meet what Vimwiki cannot give you. Universal outline exchange between outliners Meanwhile Requires Vim fluency to edit comfortably One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this Vimwiki 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 Vimwiki 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.
Can I edit the OPML result afterwards?
That depends on the target: OPML 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.
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.
