About formats

WebP is an image format developed by Google, announced on September 30, 2010, designed to provide superior compression for web images in both lossy and lossless modes. The lossy mode is derived from the VP8 video codec's intra-frame coding (the same technology used in WebM video), applying block prediction, transform coding, and adaptive quantization to photographic content. The lossless mode uses a distinct algorithm combining predictive coding, color space transforms, backward reference to repeated pixel patterns, and entropy coding. WebP also supports alpha transparency in both modes — lossy WebP with transparency is unique among common web formats, offering semi-transparent images at much smaller sizes than PNG. The format supports animated sequences as well, providing a modern alternative to GIF with full-color support and dramatically better compression. One advantage is substantial file size reduction — lossy WebP produces images 25-35% smaller than JPEG at equivalent visual quality, and lossless WebP is typically 26% smaller than PNG, directly improving web page loading speed and reducing bandwidth costs. Universal browser support provides another key strength: Chrome, Firefox, Safari, Edge, and all mobile browsers now render WebP natively, achieving the broad adoption threshold needed for practical deployment. Google's core web infrastructure (Search, YouTube thumbnails, Gmail) uses WebP extensively, and the format is supported by major CDN platforms, CMS systems, and image processing services. WebP has established itself as the primary modern alternative to JPEG and PNG for web content.

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 WEBP to PCD?

PCD is Kodak's Photo CD format — used for multi-resolution photo storage. Converting supports legacy photo archival and imaging equipment compatibility.

What opens PCD files?

IrfanView, XnView, GIMP, Adobe Photoshop, and Photo CD-compatible software handle PCD files for viewing and extraction.

Does PCD support multiple resolutions?

PCD stores images at multiple resolutions in a single file — from thumbnails to high-resolution scans — a unique multi-resolution approach.

Is PCD still in use?

PCD is a legacy format from the 1990s. It is primarily relevant for accessing old Photo CD archives and working with vintage imaging equipment.

What quality can I expect?

Your WEBP image is embedded in the PCD container — quality matches your original source at the available resolution.
