🔒 Is this safe to use?
Yes. All conversions happen locally in your browser using JavaScript. Your character files are never uploaded to any server.
📦 What is a V2 Character Card?
V2 cards are PNG images with character data embedded inside the file's metadata chunks. The image looks normal — the data hides inside.
❓ Why is my card empty?
Some platforms strip metadata on export. Try our Universal Batch tool with "Extract JSON" mode to verify the card contains data.
Finish the conversion, then learn how the format actually works.
