Check that the file contains a character definition
The picture and the definition are not always in separate files. A PNG character card may hold an avatar alongside embedded character metadata, whereas a JSON file holds structured text data. A regular PNG image can lack that metadata entirely, even if its picture looks like a character portrait.
Save an unchanged copy of the source file so you can return to it after editing. Choose a source you trust. An unfamiliar download page's claim that you need an extra browser extension is not a reason to install it.
Import, inspect and test the character
- In character creation, find the import option within the avatar area.
- Choose your supported JSON definition or metadata-bearing PNG character card.
- Check the populated name, personality and greeting for missing or unexpected text.
- Inspect advanced fields, tags and visibility yourself; do not assume every setting transferred as intended.
- Start a test conversation, then revise references left over from the card's original platform or setting.
Understand what stays behind
A card carries a character definition, not your account on another service. Importing it does not move a subscription, sign-in credentials or an entire chat history. The same wording can also lead to a different voice when our language models interpret it.
Use your own work or obtain permission for anything you reuse. Where a creator permits adaptations, follow their sharing conditions and acknowledge authorship appropriately. Changing a file's format does not make someone else's original character your own creation.
Questions
Can a Character.AI definition be used here?
If you have permission to reuse it and a compatible JSON definition or PNG character card, you can import the material. Review the resulting fields before using or sharing the character.
Why is my imported PNG missing the character text?
It may contain only an image, or its embedded definition may use an unsupported format. The .png extension identifies the image format; it does not confirm that usable character metadata is included.
