Input Format

Expects Telegram Desktop JSON export format with messages array containing id, type, date, from, from_id, and text fields.

Output

Generates a PNG image with: - 800px width - iOS-style bubble chat interface - Gray bubbles for others, blue for user messages - Circular avatars with initials - Timestamps (HH:MM format) - Proper text wrapping for long messages

Limitations

• Images, stickers, and media are not rendered
• Reply threads are not visually indicated
• Only plain text messages are fully supported
• Large exports may create very tall images

Best Practices

Handling Long Conversations

For long conversations that result in tall images (>2000px), consider:

1. ZIP Packaging: Pack the PNG into a ZIP file before sending to avoid Telegram's image compression bash zip chat.zip chat.png Then send the ZIP file as a document instead of an image.

2. Message Limits: Use --limit to generate partial exports if the full conversation is too long

Customization

這是一款實用的小工具，能將Telegram聊天記錄轉換成美觀的聊天氣泡長圖。介面風格模仿iOS設計，藍色和灰色氣泡區分清晰，帶有時間戳和頭像，整體效果不錯。功能豐富，支援高畫質輸出和中文換行處理。優點是開箱即用、操作簡單、效果直觀；不足是隻能處理純文本，不支援圖片表情，且長對話生成的圖片可能過大需要打包傳送。總體質量良好，滿足日常使用需求。
