TavernAI V2 Card Creator: The Art of Metadata Embedding

The PNG character card is the universal language of the AI roleplay world. This tool converts your raw JSON or CharacterAI text into a beautiful, data-rich V2 PNG card.

Why convert to a PNG Card?

Raw code is hard to organize. By embedding your character definitions into an image, you create a "Character Card" that can be easily managed in local frontends like SillyTavern. Instead of hunting through text files, you simply see a gallery of character portraits. Dragging one into your chat app instantly loads the entire persona, setting, and speech examples.

1. Input Source (JSON or YAML)

2. Select Your Character Portrait

Upload the PNG image you want to use as the card's face. If you don't provide one, we'll use a standard template.

Metadata Validation

Technical Details of the TavernAI V2 Spec

Our creator tool doesn't just "rename" your file. It performs a multi-step binary injection process:

1. tEXt vs zTXt Chunks

We write character data into the tEXt chunk of the PNG file using the chara key. The card is written with a standard tEXt chunk plus a compressed zTXt copy of the same data.

2. UTF-8 Safe Base64 Encoding

To prevent special symbols or non-English characters from corrupting the card, we encode the entire JSON payload into Base64. This is the requirement for 100% compatibility with the SillyTavern and TavernAI ecosystems.

3. Metadata Fields

CharacterAI fields are mapped into the V2 spec's nested data object: the name, description and greeting (first_mes) carry over directly, and the CharacterAI definition becomes the personality.

FAQ: Creating character cards

Q: Can I use a JPG image?

A: No. Character cards require the PNG format because it supports custom metadata chunks without losing quality. If you have a JPG, convert it to a PNG first before using this tool.

Q: Will this card work on my mobile phone?

A: Yes! As long as you use a compatible mobile frontend like SillyTavern Mobile, these cards will work perfectly on any device.
