Why convert ARW to PNG?

Introduced in 2006 by Sony, ARW was great for its time. But PNG (created in 1996 by PNG Development Group) offers lossless compression and 48-bit – a massive leap forward. Professional photographers often need to convert RAW files (like ARW) to web-friendly formats like PNG. This reduces file size from 30 MB+ to under 500 KB while maintaining excellent quality – perfect for online portfolios and client galleries.
