Panasonic Raw v2 (RW2) contains raw sensor data from Panasonic Lumix digital cameras.

When Should You Use HEIFS vs RW2?

HEIFS vs RW2: Key Differences

• •HEIFS uses lossy compression while RW2 uses lossless compression — this is the fundamental technical difference between the two formats.
• •Moving from HEIFS (lossless) to RW2 (lossless) means the output file will be larger — but every bit of the original is preserved.
• •Alpha channel support: RW2 lacks transparency support.
• •Storage footprint: varies for HEIFS vs 20-45MB per photo for RW2.
• •Primary audience: HEIFS is built for ios burst photos, live photos, motion photos scenarios, while RW2 focuses on panasonic/lumix camera raw editing — pick the format that matches your output requirement.
