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

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.

When Should You Use CPT vs HEIC?

Use CPT When...

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

Use HEIC When...

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

CPT vs HEIC: Key Differences

  • •CPT and HEIC diverge on compression: lossless compression for the source, lossy compression for the target.
  • •Moving from CPT (lossy) to HEIC (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
  • •Alpha channel support: HEIC handles transparency, so semi-transparent pixels from the source will be lost.
  • •File sizes: CPT files typically range Large due to layer data and HEIC files 50% smaller than equivalent JPEG.
  • •CPT is optimized for corel image editing, photo manipulation while HEIC is designed for ios photography, mobile devices — choose based on your specific workflow needs

  • ✓CPT applies lossless compression specifically calibrated for Corel image editing, photo manipulation.
  • ✓CPT enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓CPT guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find CPT support built into virtually every tool that handles Corel image editing, photo manipulation — no plugins or converters needed.

Advantages of HEIC

  • ✓HEIC compresses data using lossy methods, keeping file sizes manageable for iOS photography, mobile devices.
  • ✓Industry-wide support means HEIC files open anywhere — from legacy systems to the latest devices.
