Raw formats like CR3, ARW and NEF are each tied to one camera brand. DNG is Adobe's open alternative. For sharing, none of them is as universal as JPG.
Keep raw for editing, JPG for sharing
Your raw files are your negatives - keep them safe. When you need to send or post an image, convert to JPG first.
Converting is local and private
ChromVel converts DNG, CR3, ARW and NEF to JPG entirely in your browser. Nothing is uploaded, so your negatives stay private.
