Format Details
OPML
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.
documentHTML
HTML (HyperText Markup Language) is the standard markup language for creating web pages and web applications, maintained by the W3C. It defines the structure and content of documents using elements and tags, working alongside CSS for visual styling and JavaScript for interactivity. HTML is rendered by web browsers into the visual pages users see, and is the universal output format for documents published on the internet.
documentConverting OPML to HTML: what actually changes
OPML to HTML 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 .OPML and .HTML each hold
.OPML is a document format built for reading, printing or circulating a document, storing text, layout, fonts and images. .HTML 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 .HTML encodes text, layout, fonts and images — not what the file is about.
When this conversion is the right one
Reach for .HTML 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 .HTML to .OPML using the same tool.
Tips for a clean OPML to HTML conversion
Start from the original file
Convert the .OPML you started with, not an earlier .HTML output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Text/x-opml becomes text/html. 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 .HTML 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.
