OPML to ADOC Converter
Processing entirely on your device — large files may take a moment.
Convert ADOC exactly like AsciiDoc: into Word, Markdown or HTML. If your files are still in OPML format, this page is the shortcut: 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.
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.
How OPML compares to ADOC
| OPML | ADOC | |
|---|---|---|
| Structure | XML <outline> tree | Plain-text markup (==, [source], |===) |
| Types / schema | XML, text + attributes | UTF-8 text |
| Compatibility | RSS readers, outliners, Pandoc | Asciidoctor, Git docs, Pandoc |
| Best for | Subscriptions lists and mind maps | Technical books and large doc sets |

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 ADOC format
AsciiDoc is what happens when lightweight markup grows up. Where Markdown stops at bold and lists, AsciiDoc carries title pages, multi-level sections, callouts, admonitions, xrefs and real table syntax — enough to author entire technical books without leaving plain text. The Git and Linux-kernel documentation ecosystems standardized on it, rendered through Asciidoctor.
The format's weakness is tooling gravity: AsciiDoc converters outside the Asciidoctor/Ruby world are scarce, which is exactly where Pandoc fills the gap. Converting to Word hands manuscripts to editors who live in Office; converting to Markdown feeds modern docs sites. The section structure and tables survive the trip.
+Strengths
- ✓Book-grade structure: sections, callouts, admonitions, xrefs
- ✓Powering Git and Linux kernel docs — battle-tested at scale
- ✓Stays readable as plain text
!Limitations
- −Heavier syntax than Markdown for casual notes
- −Converter ecosystem concentrated in Asciidoctor tooling
- −Multiple dialects (legacy asciidoc vs asciidoctor)
Why convert OPML to ADOC?
Think of it as moving your file to the container that fits the job. Hierarchies only — no rich text per node ADOC works differently: Book-grade structure: sections, callouts, admonitions, xrefs If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this OPML to ADOC 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 ADOC?
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 ADOC result afterwards?
That depends on the target: ADOC 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.
