What is a PML file?

Palm Markup Language (PML) is a proprietary tagging language developed by Peanut Press (later Palm Digital Media) for formatting electronic text destined for eReader devices. Analogous to Markdown or HTML, PML utilizes specific ASCII-based tags (e.g., p for paragraphs,  for bold) to define layout and styling. These source files are typically compiled into binary PDB containers before distribution, making raw PML files rare in end-user environments.

How to open a PML file

As a plain text format, raw PML files can be opened and edited with any standard text editor such as Microsoft Notepad, Apple TextEdit, or Sublime Text. However, to view the rendered eBook as intended, the file must be compiled or converted using tools like Calibre or the legacy Dropbook compiler.
