About formats

PPTM is a macro-enabled presentation format for Microsoft PowerPoint, introduced with Office 2007 as part of the Office Open XML family. Structurally identical to PPTX — a ZIP archive containing XML parts for slides, layouts, themes, and media — PPTM adds the ability to store and execute VBA (Visual Basic for Applications) macro code within the presentation. The deliberate separation of macro-enabled (.pptm) and macro-free (.pptx) extensions was a security design decision: users and administrators can identify macro-containing files by extension alone, and security policies can block or warn about macro-enabled formats while freely allowing standard PPTX files. PPTM files store VBA projects in a dedicated binary stream (vbaProject.bin) within the ZIP package, alongside the same XML slide content used by PPTX. Macros in PowerPoint presentations power automated slide generation, custom ribbon interfaces, interactive quizzes, data-driven content updates, and integration with external data sources. One advantage is workflow automation — PPTM enables repeatable processes like generating monthly report decks from database queries or updating financial charts across dozens of slides with a single button click. The format preserves full compatibility with the OOXML specification, meaning all standard PowerPoint features — transitions, animations, embedded media, SmartArt — work identically to PPTX. PPTM is supported by Microsoft PowerPoint on Windows and macOS, with macro execution limited to the desktop application.

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 PPTM to TCR?

TCR creates extremely small text files from your presentation content — useful when storage is tight or you need a minimalist text-only record of your slides.

What reads TCR files?

TCR was built for the Psion Series 3 platform. Today, Calibre and a handful of specialized e-book readers can open and convert TCR files.

Does TCR support images?

No — TCR is a text-only format. Slide visuals from PPTM are not included; only the textual content is extracted and compressed.

How small are TCR files?

TCR uses efficient text compression, producing files significantly smaller than plain text. For text-heavy presentations, the savings are substantial.

Are PPTM macros included in TCR?

TCR stores only compressed text data — no macros, no formatting metadata, and no executable code of any kind.

Is PPTM to TCR free?

Yes — Convertio handles this conversion at no charge. Paid plans add batch processing and higher file size limits.
