Before, it encoded the content as base64, a way of turning data into plain text. Claude Code picks between two ways of encoding the bytes when it runs.\n\n**Why**\n\nRaw bytes take less room than base64 text, so the same preview sends less data.\n\n- Area: Remote Control\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
