I built a website where you can hide secret messages in emojis, images, and text (IYKYK 😏)

Hey everyone,

I built a small web tool inspired by the “IYKYK” concept where you can create and decode secret messages in different ways.

You can try it here:
https://iykykwebapp.web.app/

Some things it can do:

• Convert a normal message into emoji codes
• Hide text inside images (basic steganography)
• Encode messages so they look like normal text
• Decode messages if someone sends you one
• Everything runs client-side, so nothing is stored on a server

Example idea:
Send someone a random emoji string like
😂🔥🌊🎉🧠

If they use the site, they can decode the hidden message.

I mainly built it as a fun experiment around secret communication and internet culture (“If You Know, You Know”).

Would love feedback on:

• What other secret-message tricks I should add
• Whether the UI feels simple enough
• Ideas to make it more fun or viral

If you break it or find bugs, tell me 😄
