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 WEBP?

WebP is a modern image format that provides superior lossless and lossy compression for web images. Developed by Google, it delivers smaller file sizes while maintaining or improving visual quality.

When Should You Use PCD vs WEBP?

PCD vs WEBP: Key Differences

• •The core technical difference: PCD relies on lossy compression whereas WEBP uses lossy compression.
• •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •How transparency is handled: WEBP does not support alpha channels — transparent areas in the source will become opaque.
• •PCD files are typically 4-6MB per image at base resolution while WEBP files range 20-40% smaller than equivalent JPEG/PNG
• •PCD is optimized for photo cd scanning, legacy photo archiving while WEBP is designed for web images, responsive design, modern websites — choose based on your specific workflow needs
• •WebP achieves 25-34% better compression than JPEG at equivalent quality

Advantages of PCD

• ✓PCD compresses data using lossy methods, keeping file sizes manageable for Photo CD scanning, legacy photo archiving.
• ✓Industry-wide support means PCD files open anywhere — from legacy systems to the latest devices.
• ✓Small file sizes make PCD ideal for email, web uploads, and cloud storage.
• ✓From Adobe Photoshop to open-source alternatives, PCD works out of the box.

Advantages of WEBP

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

Common Use Cases for PCD to WEBP Conversion

• Blog and article illustrations
• Mobile app UI assets
• Product photography for marketplaces
• Digital art portfolios
• Brochure and flyer design
• Newsletter graphics

Best Practices for PCD to WEBP Conversion

• →When converting PCD to WEBP, check whether WEBP supports transparency — if not, your transparent areas will be filled with a solid color
• →Use WEBP for maximum quality archival and PCD for smaller file sizes when quality is less critical
• →Optimize images for web to reduce page load times — tools like our converter let you adjust quality settings before conversion
• →Maintain original aspect ratio to avoid distortion during conversion
• →Always keep a backup of your original files before converting
• →Choose the appropriate quality settings for your specific use case
