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.

What is CPT?

Corel PHOTO-PAINT (CPT) is the native project format for Corel PHOTO-PAINT, preserving layers, masks, and editing history.

When Should You Use WEBP vs CPT?

WEBP vs CPT: Key Differences

• •WEBP and CPT diverge on compression: lossy compression for the source, lossless compression for the target.
• •Moving from WEBP (lossless) to CPT (lossless) means the output file will be larger — but every bit of the original is preserved.
• •How transparency is handled: CPT supports transparency, so alpha information is preserved during conversion.
• •File sizes: WEBP files typically range 20-40% smaller than equivalent JPEG/PNG and CPT files Large due to layer data.
• •Primary audience: WEBP is built for web images, responsive design, modern websites scenarios, while CPT focuses on corel image editing, photo manipulation — pick the format that matches your output requirement.
• •WebP achieves 25-34% better compression than JPEG at equivalent quality

Advantages of WEBP

• ✓WEBP uses lossy compression tailored for Web images, responsive design, modern websites.
• ✓WEBP is supported natively on virtually every device, browser, and operating system.
• ✓WEBP files are compact and quick to transfer, even over slow connections.
• ✓WEBP integrates seamlessly with all major web development tools and workflows.

Advantages of CPT

• ✓CPT compresses data using lossless methods, keeping file sizes manageable for Corel image editing, photo manipulation.
• ✓Industry-wide support means CPT files open anywhere — from legacy systems to the latest devices.
• ✓Lossless quality makes CPT the gold standard for archival and master copies.
• ✓From Adobe Photoshop to open-source alternatives, CPT works out of the box.

• !Converting WEBP to CPT gives blurry output → increase the quality setting before conversion
• !Colors look different in CPT than WEBP → check color profile mismatch (sRGB vs Adobe RGB)
• !File size changed more than expected → CPT uses different compression, file size differences of 2-5x are normal
• !Transparent areas in WEBP turned white in CPT → CPT may not support transparency
