About formats

PPTX is the default file format for Microsoft PowerPoint presentations since Office 2007, based on the Office Open XML (OOXML) standard published as ECMA-376 and later adopted as ISO/IEC 29500. A PPTX file is a ZIP archive containing XML documents that describe slide content, layouts, themes, relationships, and metadata in a structured, human-inspectable hierarchy. Each slide, slide layout, and slide master is stored as a separate XML part, with media assets (images, audio, video) and embedded objects kept in dedicated directories within the package. The XML foundation enables programmatic creation and manipulation of presentations using standard XML tools and libraries — developers can generate, modify, or extract content from PPTX files without requiring PowerPoint itself. One significant advantage is openness and interoperability: the fully documented OOXML specification allows any software to read and write PPTX files, and the format is supported by LibreOffice Impress, Google Slides, Apple Keynote, and numerous other tools. Built-in ZIP compression is another practical strength — PPTX files are typically 50-75% smaller than equivalent PPT files, reducing storage and transfer costs. The format supports all modern PowerPoint features including SmartArt, 3D models, morph transitions, embedded fonts, accessibility metadata, and co-authoring capabilities. PPTX has become the standard interchange format for presentation content worldwide.

PCD (Photo CD) is a proprietary image format developed by Eastman Kodak in partnership with Philips, launched in 1992 as a system for transferring 35mm film photographs to compact discs for digital viewing and printing. Each PCD file stores a single photograph at five different resolutions in a hierarchical structure called an Image Pac: Base/16 (192x128), Base/4 (384x256), Base (768x512), 4Base (1536x1024), and 16Base (3072x2048), with optional 64Base (6144x4096) on Pro Photo CD discs. Images are stored in Kodak's proprietary YCC color space (a variant of CIE Lab via the Photo YCC color model), which captures a wider gamut than sRGB, at 8 bits per component in the luminance channel and subsampled chrominance. The multi-resolution pyramid is encoded using a progressive scheme: the Base image is stored directly, and each higher resolution is stored as a residual (difference) that refines the upscaled previous level, keeping the total file size manageable. One advantage is the exceptional scan quality: Photo CD scans were performed on Kodak's professional PIW (Photo Imaging Workstation) scanners by trained operators, producing consistently excellent results from 35mm negatives and slides — often better than what contemporary consumer flatbed scanners could achieve. The multi-resolution structure is another notable feature: a single PCD file serves needs from thumbnail browsing to high-resolution printing without separate file versions. PCD files can be read by Adobe Photoshop, ImageMagick, GIMP (via plugin), IrfanView, and XnView, ensuring continued access to the millions of Photo CD images created during the format's commercial peak in the 1990s.

Frequently Asked Questions

Why convert PPTX to PCD?

PCD provides multi-resolution storage in a single file — useful for archival workflows where the same slide visual is needed at different sizes without re-rendering.

How do I open PCD files?

IrfanView, XnView, Adobe Photoshop, and ImageMagick all read Kodak Photo CD images. Most professional photo management software supports the format.

What resolutions does PCD support?

PCD stores images at multiple resolutions simultaneously — from thumbnail size up to 6144x4096 pixels — letting viewers choose the appropriate level of detail.

Is PCD still used today?

PCD is largely a legacy archival format from the Kodak Photo CD era. It remains useful for accessing historical photo archives and specialized scanning workflows.

Is PPTX to PCD free on Convertio?

Yes, Convertio converts PPTX to PCD at no charge. Premium plans offer batch processing, larger uploads, and priority queue access for heavier workloads.

Does PCD support 24-bit color?

PCD encodes images in full 24-bit color with luminance-chrominance separation — preserving rich color data that matches the quality of professional film scanning.
