PCD Image Conversion: Batch Convert, Resize & Organize
PCD (Photo CD) is Kodak's 1992 format for storing scanned photographs on CD-ROM. Each image is stored at five resolutions (192×128, 384×256, 768×512, 1536×1024, 3072×2048) in a single file, letting software pick the size it needs without resampling. Kodak offered PCD as a service — you mailed in film, got back a CD with digitized images. The product line ended in 2004, but the files persist in archives.
Contenta Converter PREMIUM lets you open, convert, and batch process PCD files into modern formats like JPG, PNG, TIFF, PDF, and more. Optimize file size, keep important metadata, and prepare images for web, print, or long-term archiving in just a few clicks.

The product line ended in 2004, but the files persist in archives. | JPEG 2000是一個基於小波的圖像壓縮標準。JPEG 2000的目的不僅是改善JPEG的壓縮性能，它也增添（或改善）了很多例如可擴展性和可修改性的功能。 |
| 優點 | Multi-resolution design was ahead of its time — pick any of five sizes without server-side resizing. 12-bit color per channel at higher resolutions, YCC color space, Huffman coding. Decent compression for 1992. | 文件大小小很多，質量卻與JPEG不相上下 |
| 缺點 | Kodak discontinued Photo CD support in 2004. Most modern software opens the highest resolution stored but cannot write new PCD files. The format's quirks (YCC instead of RGB, reversed scan-line order on Pro PhotoCD) require specialized decoders; Contenta Converter PREMIUM handles this. | 沒那麼受歡迎，需要更多電腦資源 |
