Format Details
AsciiDoc
AsciiDoc is a lightweight text-based markup language designed for authoring technical documentation, books, articles, and presentations in plain text files. It provides a richer feature set than Markdown, including built-in support for tables, cross-references, document includes, and complex layouts. AsciiDoc is widely used by technical publishers and open-source projects, and can be converted to HTML, PDF, EPUB, and DocBook.
documentOPML
OPML (Outline Processor Markup Language) is an XML-based format designed for exchanging hierarchical outline and list structures between applications. It is most commonly used to export and import RSS/Atom feed subscription lists between news readers and podcast apps. OPML also serves as a portable format for structured notes, project outlines, and hierarchically organized content in productivity tools.
documentConverting ADOC to OPML: what actually changes
AsciiDoc to OPML is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.
What .ADOC and .OPML each hold
.ADOC is a document format built for reading, printing or circulating a document, storing text, layout, fonts and images. .OPML is a document format built for reading, printing or circulating a document, storing text, layout, fonts and images. Converting between them is a decision about which of those two jobs the result needs to do.
What changes in the conversion
Both files belong to the document category, so this is a like-for-like repackage: the same kind of content, stored in a different container. What changes is how .OPML encodes text, layout, fonts and images — not what the file is about.
When this conversion is the right one
Reach for .OPML when the software, device or platform you are sending to expects it — the content is the same document, only the packaging differs. The reverse direction works the same way, so you can always convert back from .OPML to .ADOC using the same tool.
Tips for a clean ADOC to OPML conversion
Start from the original file
Convert the .ADOC you started with, not an earlier .OPML output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Text/asciidoc becomes text/x-opml. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.
Keep the output next to the original
Save the .OPML file alongside the source rather than replacing it. Having both means you can try a different target later without hunting down the original again.
Limits worth knowing
Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge document files, split or compress the source first.
