LRF at a glance
LRF
Convert to LRF when maintaining compatibility with older Sony Reader libraries or when handling ebook archives tied to that device family.
In most present-day publishing workflows the practical direction is away from LRF and toward EPUB or Kindle formats.
Use it only where legacy Sony support is still required.
MD at a glance
MD
Convert to Markdown when the output should remain easy to edit in plain text, store in Git, review in diffs, or feed into automated publishing systems.
It is ideal for documentation, articles, developer guides, release notes, and notes that will later be rendered into richer formats.
Use Markdown when semantic structure matters more than exact page layout.
