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.

PCT (also known as PICT) is a metafile graphics format originally developed by Apple Computer and introduced alongside the original Macintosh in January 1984. PCT files can contain both vector drawing commands and raster bitmap data, encoded as a sequence of QuickDraw drawing operations — the same graphics primitives used by the Macintosh operating system for all on-screen rendering. The format evolved through two major versions: PICT 1, which recorded basic QuickDraw operations (lines, rectangles, ovals, text, 1-bit bitmaps) in a compact format suitable for the original Macintosh's limited memory, and PICT 2, introduced with Color QuickDraw in 1987, which extended the format to support 24-bit color, multiple color spaces, and embedded JPEG-compressed data. PCT files begin with a 512-byte header (originally used for resource fork information), followed by the picture size, bounding rectangle, and a sequence of opcodes that define the drawing operations. During the Macintosh's commercial ascendancy, PICT was the universal graphics interchange format on Mac OS — the system clipboard used PICT for all graphical copy/paste operations, and most Mac applications could import and export the format. One advantage is the hybrid vector/raster nature: PCT files from the QuickDraw era preserve both scalable drawing commands and pixel data in a single format, enabling resolution-independent output for the vector portions. PICT's historical significance as the native Mac graphics format throughout the classic Mac OS era (1984-2001) provides another dimension. PCT files remain readable by Preview on macOS, ImageMagick, XnView, LibreOffice, and GIMP.

Frequently Asked Questions

Why convert PPSX to PCT?

PCT is the classic Macintosh image format. Converting PPSX to PCT makes slide visuals compatible with vintage Mac software, Classic Mac OS, and DTP archives.

How do I open PCT files?

macOS Preview opens PCT files. On other platforms, IrfanView, XnView, and ImageMagick handle the format. Adobe Illustrator can also import PICT/PCT images.

Is PCT the same as PICT?

Yes — PCT and PICT refer to the same Apple QuickDraw image format. PCT is the common file extension, while PICT is the format name used in documentation.

Does PCT support vector graphics?

The QuickDraw PICT format can store both vector and raster data. However, PPSX slides are rasterized during conversion — producing bitmap PCT images.

Is PCT still relevant?

PCT is largely a legacy format, but it remains important for accessing historical Mac archives, retro computing, and compatibility with older desktop publishing tools.

Is PPSX to PCT conversion free?

Yes — Convertio provides free PCT conversion. Premium accounts unlock larger uploads and priority processing for heavy workloads.
