A tool that opens a SillyTavern character card (the chara JSON embedded as base64 in a PNG's "chara" tEXt chunk) right in your browser so you can inspect and edit it. Beyond the core fields — name, description, personality, scenario, first_mes (greeting) and mes_example — it lets you edit the chara_card_v2 extras: system_prompt, post_history_instructions, creator_notes, tags, alternate greetings, creator and character version. Load a legacy v1 (flat) card and it's detected automatically; on export it's saved as chara_card_v2 with the v1 fields mirrored at the root, so it stays compatible. Drop a plain PNG with no chara data and it opens with empty fields, so you can use it as a maker to build a brand-new card from any image. There are two ways to export: download the PNG card with the data embedded, or pull out the contents as pretty-printed JSON (character card png to json) via download or copy. The pixels are never touched — it's a lossless edit that only swaps the tEXt chunk. The key feature is that it runs fully locally: neither the image nor the card text is ever uploaded or sent anywhere; everything happens in your browser. It's part of the same no-upload family as png-info and gguf-info.
