→Save a master copy in a lossless format before converting to CR3 — you cannot recover detail lost during lossy compression
→Check the color profile: CPT images may use a wider gamut than CR3 supports, causing a visible shift after conversion
→Resize images to the final display dimensions before converting — this avoids unnecessary processing of oversized files
→Run a single test conversion first to verify quality meets your standards
→Strip unnecessary metadata to reduce file size after conversion
