OPML (Outline Processor Markup Language) is an XML format for outlines. It is commonly used to exchange podcast and RSS subscriptions.
DocBook is a semantic XML markup language for technical documentation. It separates content from presentation, allowing multiple output formats.
FreeFileConvert uses tuned encoding for OPML to DBK conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload OPML files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized DBK results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent DBK audio with dependable progress tracking.
OPML files contain hierarchical outline nodes with attributes. They are widely used for feed aggregator import/export.
DocBook documents can be transformed to HTML, PDF, EPUB, and man pages using XSLT stylesheets.
Upload your document file in the OPML format from your device, Dropbox, or Google Drive.
Select DBK as the output format and click Convert. Adjust optional settings if needed.
