Format Details

ebookOPML
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 PDB to OPML: what actually changes
PDB 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 .PDB and .OPML each hold
.PDB is a ebook format built for reading a book on an e-reader or in an app, storing chapters, images and reading order. .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 when categories differ
This conversion translates chapters, images and reading order into text, layout, fonts and images so the result can be used for reading, printing or circulating a document. The meaning of the file is preserved; the way it is stored, and some format-specific detail, changes with the target.
When this conversion is the right one
Reach for .OPML when you need a file for reading, printing or circulating a document, starting from reading a book on an e-reader or in an app. If that is not what you are after, check what else .PDB converts to before committing to this target.
Tips for a clean PDB to OPML conversion
Start from the original file
Convert the .PDB 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
Application/x-pdb 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 ebook files, split or compress the source first.
