AVIF (AV1 Image File Format) is a new image format based on the AV1 video codec. It provides outstanding image quality and compression efficiency.

When Should You Use CUR vs AVIF?

CUR vs AVIF: Key Differences

• •CUR uses lossless compression while AVIF uses lossy compression — this is the fundamental technical difference between the two formats.
• •The switch from lossless compression to lossy compression means you gain significant space savings while accepting minor quality trade-offs.
• •Alpha channel support: AVIF handles transparency, so semi-transparent pixels from the source will be lost.
• •Storage footprint: Very small, typically under 50KB for CUR vs 40-50% smaller than JPEG/PNG for AVIF.
• •CUR is optimized for windows ui cursors, mouse pointer graphics while AVIF is designed for modern web, next-generation web applications — choose based on your specific workflow needs

Advantages of CUR

• ✓CUR uses lossless compression tailored for Windows UI cursors, mouse pointer graphics.
• ✓CUR is supported natively on virtually every device, browser, and operating system.
• ✓CUR files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓CUR integrates seamlessly with all major creative tools and workflows.

Advantages of AVIF

• ✓At its core, AVIF relies on lossy encoding — a design choice that makes it perfect for Modern web, next-generation web applications.
• ✓You won't run into compatibility issues with AVIF — it's a universal standard across platforms.
• ✓File size management with AVIF: aggressive compression with minimal visible quality loss.
• ✓Every major application in the Modern web, next-generation web applications space supports AVIF natively.
