🔒 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.
🩹 How do I check or repair a broken character card?
Use the free JSON Validator to find the exact line of a JSON error and check V1, V2 and V3 fields, then the Broken Card Repair tool to fix invalid JSON, wrong card structure and damaged PNG metadata. The Token Counter estimates how many tokens each field uses. All three run in your browser with no upload.
Finish the conversion, then learn how the format actually works.
Repair docs, specification deep dives, and privacy guides for when you need more than a quick export.
