What is PCD?

Kodak Photo CD (PCD) is a high-resolution image format for storing scanned photos on CD, supporting multiple resolutions from thumbnail to 3072x2048.

What is WEBP2?

WebP2 is the next-generation image format from Google, building on the success of WebP with significantly improved compression efficiency. It targets 30% additional size reduction over WebP at equivalent quality.

When Should You Use PCD vs WEBP2?

PCD vs WEBP2: Key Differences

• •PCD uses lossy compression while WEBP2 uses lossy compression — both take the same approach to file size management.
• •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •Alpha channel support: WEBP2 handles transparency.
• •Storage footprint: 4-6MB per image at base resolution for PCD vs 30-50% smaller than JPEG, 15-20% smaller than WebP for WEBP2.
• •Use case fit: PCD targets photo cd scanning, legacy photo archiving and WEBP2 targets high-efficiency web graphics, next-gen responsive images — your choice depends on which workflow stage you are serving.

Advantages of PCD

• ✓At its core, PCD relies on lossy encoding — a design choice that makes it perfect for Photo CD scanning, legacy photo archiving.
• ✓You won't run into compatibility issues with PCD — it's a universal standard across platforms.
• ✓File size management with PCD: aggressive compression with minimal visible quality loss.
• ✓Every major application in the Photo CD scanning, legacy photo archiving space supports PCD natively.

Advantages of WEBP2

• ✓The lossy nature of WEBP2 means file sizes stay reasonable while handling High-efficiency web graphics, next-gen responsive images efficiently.
• ✓From mobile devices to enterprise servers, WEBP2 is recognized and supported everywhere.
• ✓Storage and bandwidth costs drop significantly when using WEBP2 thanks to its efficient compression.
• ✓WEBP2 is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Common Use Cases for PCD to WEBP2 Conversion

• Email marketing campaigns
• Presentation graphics
• Blog and article illustrations
• Mobile app UI assets
• Product photography for marketplaces
• Digital art portfolios
