PPTM to LRF conversion is the process of transforming a PowerPoint presentation file that contains macros (PPTM) into the Sony/LRF eBook/reader format (LRF). This conversion extracts slide content—text, images, and basic layout—and repackages it into a linear, reflowable reader format suitable for compatible e-readers and apps.

PPTM is a Microsoft PowerPoint macro-enabled presentation format, primarily used for creating and editing slideshows with embedded macros. LRF is a proprietary eBook format designed for Sony devices, optimized for reading and portability rather than presentation editing. While PPTM files focus on interactive content and editing features, LRF files prioritize simplified, readable formats for e-readers.
Keep individual PPTM files below 50–100 MB for optimal speed and to avoid memory issues on conversion services.
Preserve quality by embedding fonts and using high-resolution images; consider exporting complex slides as images to maintain appearance.
For batch conversions, compress assets and remove unused slides or large embedded objects to speed processing and prevent timeouts.
Note format limitation: LRF is primarily a linear reader format and may not support animations, slide transitions, embedded macros, or interactive elements from PPTM.
