| Description | In some Outlook for Mac export/eDiscovery workflows, message data is represented as XML files (often with a companion attachments folder structure). If your files are named .opf but contain XML, treat this as an exporter-specific container for Outlook item metadata + body + attachment references rather than a single universal standard. |

An .opf file is the package manifest of an EPUB e-book, usually named content.opf. It is not the book's text — it is the XML index that lists the book's metadata, every file inside the book, and the reading order. Open it in a normal reader and you get raw XML. Converting OPF to PDF renders that manifest as a readable document, so you can review the e-book's title, author, identifier, file list, and spine without an XML editor.
A .opf file is the Open Packaging Format file of an EPUB e-book, the central XML document that ties the book together. It holds three things: the metadata (title, author, language, and unique identifier), the manifest listing every file the book contains (XHTML chapters, images, stylesheets, fonts), and the spine that sets the linear reading order. It is the package and table-of-contents file for the EPUB — a description of the book's structure, not the prose itself. Each EPUB normally has one .opf, commonly named content.opf.
| Property | OPF (.opf) | PDF (.pdf) |
|---|---|---|
| Purpose | EPUB package manifest and metadata | Fixed, portable document for reading |
| What it holds | Metadata, file manifest, and reading order | Rendered page layout of text and images |
| Contains the book's prose | No — it indexes the files that do | Shows whatever content is rendered into it |
| Format | XML | Open ISO document standard |
| Readable as-is | Raw XML, not formatted for reading | Yes, in any PDF viewer |
| Opens in | EPUB tools and XML editors | Any PDF reader, browser, or mobile device |
The converter reads the .opf XML and parses its three sections — the metadata, the manifest, and the spine. The book's title, author, language, and identifier are pulled from the metadata; the manifest's list of files and the spine's reading order are laid out as readable sections. That structured content is rendered to a PDF page. The result is a fixed document that presents the EPUB's package information in a form you can read, search, and file, without opening the raw XML or an EPUB authoring tool.
