OPML to Textile Converter
Processing entirely on your device — large files may take a moment.
Outline Processor Markup and Textile Markup 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 Textile when migrating Redmine wikis or old CMS content into Markdown, Word or modern HTML.
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.
How OPML compares to Textile
| OPML | Textile | |
|---|---|---|
| Structure | XML <outline> tree | Plain-text markup (h1., *b*, bq.) |
| Types / schema | XML, text + attributes | UTF-8 text, no binary payload |
| Compatibility | RSS readers, outliners, Pandoc | Redmine, Textpattern, Pandoc |
| Best for | Subscriptions lists and mind maps | Legacy wiki and CMS migration |

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 Textile format
Textile, written by Dean Allen in 2002, is the lightweight markup that taught the web that plain text could become HTML. Its grammar is compact and humane: "h1." makes a heading, "*bold*" and "_italic_" style inline, "bq." quotes, "* " builds lists, and "!image.png!" embeds pictures. Textpattern and Redmine standardized it, and thousands of forum posts and issue trackers were written in it through the 2000s.
Reading Textile back into an editable format is the real migration problem: the content is fine, the syntax is just no longer what new tools accept. Pandoc parses the full grammar — tables, footnotes, definition lists — and re-emit it as Markdown, Word, HTML or anything modern. Structure survives; only the plumbing changes.
+Strengths
- ✓Human-readable plain text — diffs and version control work naturally
- ✓Full-featured: tables, footnotes, definition lists, code blocks
- ✓Still the native format of Redmine and Textpattern installs
!Limitations
- −Effectively frozen since the 2000s — few new tools accept it
- −Smaller ecosystem than Markdown for converters and editors
- −Flavors differ slightly between Textpattern and Redmine
Why convert OPML to Textile?
There is a concrete reason this conversion exists: Hierarchies only — no rich text per node Textile sidesteps that — Human-readable plain text — diffs and version control work naturally If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this OPML to Textile 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 Textile?
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.
Will the layout of my OPML file be preserved exactly?
This converter renders your OPML content into Textile 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.
