Convert OPML to PDF

Understanding OPML and PDF file formats

OPML (Outline Processor Markup Language) is an XML-based file format primarily used for exchanging outline-structured information between applications. It is commonly used for sharing lists of RSS feeds or hierarchical note structures. PDF (Portable Document Format), developed by Adobe, is a widely used file format for presenting documents in a manner independent of application software, hardware, and operating systems. PDFs preserve the formatting and layout of the original document, making them ideal for sharing and printing.

Why convert OPML to PDF?

Converting an OPML file to PDF allows you to share, print, or archive your outline data in a universally accessible and visually consistent format. This is especially useful for presentations, documentation, or when you need to distribute your outlines to users who may not have OPML-compatible software.

How to convert OPML to PDF

Since OPML is a specialized format, direct conversion tools are limited. The most effective method involves first opening the OPML file in an outliner or note-taking application that supports OPML import, then exporting or printing the outline as a PDF.

Recommended software for OPML to PDF conversion

• Freeplane: A free, open-source mind mapping and outlining tool that supports OPML import and PDF export.
• MindManager: A professional mind mapping tool with robust OPML and PDF support.
• Workflowy: An online outliner that can import OPML and print to PDF via browser print functionality.

Step-by-step conversion using Freeplane

1. Open Freeplane and go to File → Import → OPML to load your OPML file.
2. Once the outline is loaded, adjust formatting as needed.
3. Go to File → Export → PDF to save your outline as a PDF document.

Online alternatives

Some online converters, such as Zamzar or CloudConvert, may support OPML to PDF conversion, but results can vary depending on the complexity of your outline. For best results, use a dedicated outliner application.

Tips for best results

• Review the outline structure after import to ensure all data is correctly formatted.
• Customize the appearance before exporting to PDF for better readability.
• Test with a sample file to verify compatibility with your chosen software.
