OPML to POTM 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. Extract text and structure from POTM templates like any PPTX.
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 POTM format
PPTX is the modern PowerPoint deck: a zip of XML parts describing slides, shapes, text runs and media. That structure is exactly why text can be extracted faithfully without PowerPoint — every word on every slide is in the package, with its slide number.
One honest limit: extraction is about words, not looks. Slide layouts, backgrounds, animations and images do not survive a text export — the output is the content of the deck, not a picture of it.
+Strengths
- ✓Text and slide order preserved exactly
- ✓Opens in PowerPoint, Keynote, WPS, Slides
- ✓Zip+XML structure is machine-friendly
!Limitations
- −Text export loses layout and visuals
- −Charts and tables flatten to text
Why convert OPML to POTM?
There is a concrete reason this conversion exists: Hierarchies only — no rich text per node POTM sidesteps that — Text and slide order preserved exactly If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this OPML to POTM 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 POTM?
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.
Will OPML to POTM keep the slide order?
Yes — slides are read from the file in their real order and numbered, so the output follows the deck exactly.
What about speaker notes?
The main extraction covers slide text; notes live in a separate part of the package and are not included in this export.
