Compressed Text Extraction

TCR pulls raw text from your PPSX slides and compresses it into one of the smallest e-book formats available — ideal for archival or low-storage scenarios.

Nearly Instant Conversion

Text extraction and compression is extremely fast. Upload your PPSX and receive the TCR output in seconds, regardless of how many slides you have.

Legacy Device Compatibility

TCR was built for Psion handhelds, and it still works on those devices. Modern tools like Calibre also read TCR, bridging old hardware and new workflows.

About formats

PPSX (PowerPoint Slideshow XML) is the Open XML counterpart to the legacy PPS format, introduced by Microsoft with Office 2007. Like PPTX, a PPSX file is a ZIP archive containing XML parts that describe slides, layouts, themes, and media assets according to the Office Open XML specification. The distinguishing characteristic is behavioral: opening a PPSX file launches the presentation directly in full-screen slideshow mode, bypassing the editing environment. This makes PPSX the preferred format for distributing finalized presentations where the audience should experience the content as a seamless visual narrative without exposure to the editing interface, slide sorter, or speaker notes panel. PPSX files support every visual feature available in PPTX including transitions, animations, embedded video and audio, hyperlinks, SmartArt, charts, and custom slide timings. One advantage is streamlined delivery — a PPSX file attached to an email or shared via a link opens as a polished presentation with a single click, requiring no instruction to the recipient. The XML-based foundation provides another benefit: PPSX files are typically much smaller than equivalent PPS files due to built-in ZIP compression, and their contents can be inspected or modified programmatically using standard XML tools. The format is supported for playback in PowerPoint, LibreOffice Impress, Google Slides (after upload), and various mobile presentation apps, ensuring broad cross-platform reach for distributed slide decks.

TCR (Text Compression for Reader) is a compressed plain-text ebook format developed by Barry Childress in the early 1990s for the Psion Series 3 family of palmtop computers. The format was created for Childress's Reader3 application, a text file viewer that needed to fit large books into the Psion's extremely limited storage — typically 128 KB to 2 MB of available memory. TCR uses a dictionary-based compression scheme derived from the earlier ZVR format by Ian Giddings, replacing repeated byte sequences with single-byte tokens that reference a header dictionary. This straightforward approach achieves compression ratios of roughly 40-60% on typical English prose while requiring minimal CPU resources for decompression. The Psion Series 3 ran on a 3.84 MHz NEC V30 processor with no floating-point unit, so TCR's low computational overhead was essential for smooth page-by-page reading. A key advantage is remarkable storage efficiency for its simplicity — users could carry dozens of novels on removable SSD cards that held only a few hundred kilobytes. The format found a dedicated user community among Psion enthusiasts who built libraries of compressed literature for portable reading years before smartphones existed. Though the Psion platform faded from the market in the early 2000s, TCR files can still be opened and converted by modern ebook tools, and the format stands as an early example of purpose-built mobile reading technology from the pre-smartphone era.

Frequently Asked Questions

Why convert PPSX to TCR?

TCR offers highly compressed text storage. If you need slide content in a minimal, text-only format — especially for legacy Psion hardware — TCR delivers.

What reads TCR files?

TCR was created for Psion handheld devices. Today, Calibre and a few legacy reader applications can open and convert TCR files on modern computers.

Does TCR retain slide formatting?

No — TCR is a compressed plain text format. All visual formatting, images, and layout information from your PPSX slides are stripped, leaving only raw text.

How small are TCR files?

TCR uses compression designed for early handhelds, producing very small text files. Expect significantly smaller output than TXT for the same slide content.

Can I convert TCR to EPUB or PDF later?

Yes — Calibre handles TCR input and converts it to EPUB, PDF, MOBI, and other modern formats with ease.

Is PPSX to TCR free?

Convertio provides this conversion at no charge. Premium plans are available for users with high-volume or enterprise needs.
