What is CUR?

Windows Cursor (CUR) is the mouse cursor format for Windows, supporting static and animated pointers with hotspot definitions.

What is WEBP2?

WebP2 is the next-generation image format from Google, building on the success of WebP with significantly improved compression efficiency. It targets 30% additional size reduction over WebP at equivalent quality.

When Should You Use CUR vs WEBP2?

CUR vs WEBP2: Key Differences

• •CUR uses lossless compression while WEBP2 uses lossy compression — this is the fundamental technical difference between the two formats.
• •Converting from CUR to WEBP2 changes compression type: lossy source becomes smaller but with some quality tradeoff.
• •How transparency is handled: WEBP2 does not support alpha channels — transparent areas in the source will become opaque.
• •Storage footprint: Very small, typically under 50KB for CUR vs 30-50% smaller than JPEG, 15-20% smaller than WebP for WEBP2.
• •Use case fit: CUR targets windows ui cursors, mouse pointer graphics and WEBP2 targets high-efficiency web graphics, next-gen responsive images — your choice depends on which workflow stage you are serving.
