Convert PML to TCR

The PML (Palm Markup Language) file is a format developed by Palm Inc for structuring eBooks, primarily used with eReader devices. It employs tags to format text, similar to HTML, and is compiled into a PDB file for display on Palm devices. Introduced to facilitate eBook reading on early handheld devices, PML played a key role in the evolution of digital book formats.

The TCR file extension stands for Text Compressed for Readability, originally used by Psion Series 3 palmtop devices in the early 1990s. It stores eBooks in a proprietary format that offers better compression than PalmDOC, making it suitable for the limited storage of handheld devices. Despite the discontinuation of Psion devices, TCR files can still be read using modern eReaders like Sumatra PDF.
