Convert Documents to TCR Online — Free eBook Converter
Use this free online converter to transform documents from a wide range of input formats into TCR eBook format — a compact format designed for reading on Psion and similar handheld devices — with no software installation or registration required.
What is TCR format?
TCR (Text Compressed Reader) is a simple, compressed plain-text eBook format originally developed for the Psion Series 3 and Series 5 personal digital assistants (PDAs). It uses a basic substitution compression scheme to shrink plain-text content, making it well suited to the limited storage and processing power of early handheld devices. TCR files typically have the .tcr extension and contain no rich formatting, images, or DRM — just readable, compressed text.
Although TCR is a legacy format largely superseded by EPUB, MOBI, and AZW on modern e-readers, it retains a niche audience among collectors and users of vintage Psion hardware or compatible emulators.
Why convert to TCR?
- Psion & vintage PDA compatibility: TCR is one of the native formats supported by Psion palmtops and several classic handheld e-reader apps.
- Minimal file size: The compression scheme keeps files very small, useful when storage is at a premium.
- Simple text preservation: When you need a no-frills, stripped-down version of a document for older devices, TCR is a reliable choice.
- Emulator support: Various Psion emulators on desktop and mobile can open TCR files, allowing you to revisit content on modern hardware.
