OPML to RTF Converter
Processing entirely on your device — large files may take a moment.
Outline Processor Markup and Rich Text Format 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 to RTF when the recipient's toolchain is ancient, locked-down or unknown — it is the lowest-common-denominator rich text that opens anywhere.
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 RTF

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 RTF format
RTF is Microsoft's 1987 rich-text format, and it refuses to die for a good reason: the file is plain ASCII with readable backslash commands, so any program ever written can open it. WordPad, Word, TextEdit, LibreOffice, ancient mainframe editors — RTF is the lowest common denominator of formatted text.
It carries bold, italics, fonts, colors, tables and images, but its layout fidelity is modest by design — think "formatted text", not "typeset page". That makes RTF the right target when the recipient's toolchain is unknown, ancient or locked down: it opens everywhere and keeps the formatting that matters.
+Strengths
- ✓Opens in literally every word processor
- ✓Plain-text based — never corrupted by email or old systems
- ✓Keeps bold/italic/tables/images without a full office suite
!Limitations
- −No templates, macros or document automation
- −Layout fidelity far below DOCX/PDF
- −Verbose encoding makes files larger than DOCX
Why convert OPML to RTF?
Think of it as moving your file to the container that fits the job. Hierarchies only — no rich text per node RTF works differently: Opens in literally every word processor 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 RTF 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 RTF?
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 RTF result afterwards?
That depends on the target: RTF 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.
