When Should You Use AVIF vs CUR?

AVIF vs CUR: Key Differences

• •AVIF uses lossy compression while CUR uses lossless compression — this is the fundamental technical difference between the two formats.
• •Moving from AVIF (lossless) to CUR (lossless) means the output file will be larger — but every bit of the original is preserved.
• •How transparency is handled: CUR supports transparency, so alpha information is preserved during conversion.
• •Storage footprint: 40-50% smaller than JPEG/PNG for AVIF vs Very small, typically under 50KB for CUR.
• •Primary audience: AVIF is built for modern web, next-generation web applications scenarios, while CUR focuses on windows ui cursors, mouse pointer graphics — pick the format that matches your output requirement.
