OPML (Outline Processor Markup Language) is an XML format for outlines. It is commonly used to exchange podcast and RSS subscriptions.
From the 70's to 2007 the open source .txt filename extension format commonly referred to plain text documents encoded using the ASCII character set. To support internationalization and localization, .txt text documents are today text files encoded using the UTF-8 or UTF-16LE standard which is a superset of the ASCII character set. Text documents of type .txt typically have minimal formatting for example no support for bold or italic characters or support for bullet points etc. This allows .txt documents to use minimum storage space and be platform independent as long as the operating system supports the underlying encoding character set used to create the .txt document. On windows .txt file support has existed since 1985 when Windows 1.0 was released and since then has been mostly associated with the notepad application on Microsoft Windows.
FreeFileConvert uses tuned encoding for OPML to TXT 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 TXT 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 TXT audio with dependable progress tracking.
OPML files contain hierarchical outline nodes with attributes. They are widely used for feed aggregator import/export.
Unicode (UTF-8 or UTF-16LE) is the defacto character encoding set for .txt files. It is supported by all major operating systems, with many having native applications that can open .txt documents.
Upload your document file in the OPML format from your device, Dropbox, or Google Drive.
Select TXT as the output format and click Convert. Adjust optional settings if needed.
Download the converted document file. Each file stays available for up to 5 downloads.
