Hide your secrets within your messages. The algorithm converts any text into invisible Unicode characters and hides it inside any message. It is also capable of hiding images!

• Encode text and images inside any string
• Decode the string into a hidden message or an image
• Share encoded messages by any modern messenger
• Open-source (yaaaay!)
• Uses WASM to provide the best performance

• The current implementation only allows images under 10-20 kilobytes. Multiple megabytes of image raw binary is hard to hide within simple messages like "hello" and results in a few thousand character string "hello" (invisible Unicode...).
• Some messengers might still not allow or support a few Unicode characters. There are a limited amount of invisible Unicode characters available and it is hard to make every messenger support it.

To create a production release, build with:

npm run build

For development use following commands:

npm run dev

# or start the server and open the app in a new browser tab
npm run dev -- --open
