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.

What is ARW?

Sony Alpha Raw (ARW) is Sony's proprietary raw image format containing unprocessed sensor data from Sony Alpha and Cyber-shot cameras.

When Should You Use WEBP2 vs ARW?

WEBP2 vs ARW: Key Differences

• •WEBP2 uses lossy compression while ARW uses lossless compression — this is the fundamental technical difference between the two formats.
• •Moving from WEBP2 (lossless) to ARW (lossless) means the output file will be larger — but every bit of the original is preserved.
• •Alpha channel support: ARW lacks transparency support.
• •Storage footprint: 30-50% smaller than JPEG, 15-20% smaller than WebP for WEBP2 vs 20-40MB per photo for ARW.
• •Use case fit: WEBP2 targets high-efficiency web graphics, next-gen responsive images and ARW targets sony camera post-processing, professional editing — your choice depends on which workflow stage you are serving.
