OPML to PDF Converter
Processing entirely on your device — large files may take a moment.
Outline Processor Markup and PDF Document 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 PDF when you need a fixed, print-ready layout that looks identical everywhere and cannot be accidentally reflowed or edited.
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.

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 PDF format
PDF (Adobe, 1993; ISO 32000 since 2008) exists for one promise: the document looks identical everywhere, forever. Fonts get embedded, layout is fixed to the point, and a contract printed from a 2003 file renders the same as one created this morning. That fixed-layout guarantee made it the standard for invoices, manuals, forms, e-books and anything with legal or financial weight.
The same design is what makes PDFs stubborn. They are meant to be presented, not edited — text lives in positioning operators rather than paragraphs, so extraction and re-flow are approximations. Scanned PDFs are worse: pure images with no text layer at all until OCR enters the picture. Still, no other format comes close for final-form document delivery.
+ Strengths
- ✓Pixel-identical rendering on every device and printer
- ✓Fonts, images and color profiles travel inside the file
- ✓Mature ecosystem: forms, signatures, annotations, encryption
! Limitations
- −Hard to edit by design — even small changes need tooling
- −Text extraction is an approximation, not a conversion
- −Scanned PDFs are images without OCR
Why convert OPML to PDF?
Think of it as moving your file to the container that fits the job. Hierarchies only — no rich text per node PDF works differently: Pixel-identical rendering on every device and printer 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 PDF 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.
How does the layout of my document turn out?
Pages keep their proportions automatically: images are fitted to A4-equivalent pages with sensible margins, and PDF pages are rendered at high resolution. You can preview the result right in the browser before downloading.
Can I edit the PDF result afterwards?
That depends on the target: PDF 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.
Will the layout of my OPML file be preserved exactly?
This converter renders your OPML content into PDF 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.
