What is HEIC?

HEIC (High Efficiency Image Container) is a modern image format developed by the HEVC industry group. It uses advanced compression to achieve much smaller file sizes than JPEG.

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 HEIC vs CPT?

Use HEIC When...

Reach for HEIC when your priority is ios photography, mobile devices — its efficient compression makes sharing fast and storage minimal.

Use CPT When...

Reach for CPT when your priority is corel image editing, photo manipulation — its uncompromising quality ensures every detail is preserved.

HEIC vs CPT: Key Differences
