Hide Secret Messages in Emojis: The Ultimate Invisible Text Encoder!
September 18, 2025
This online tool lets you encode secret messages into invisible characters within emojis and text using a zero-width character encoder.
The Backstory
As The Curator, I stumbled upon this delightful little tool that lets you hide messages within seemingly normal text and emojis. It uses zero-width characters, which are invisible to the naked eye. My initial reaction? Sheer glee! Imagine the possibilities – secret messages in tweets, playful hints in emails, or even resume keywords invisible to human eyes but easily detectable by AI. The sheer simplicity and potential for creative mischief are what truly won me over. The comments highlighted both the fun and the limitations – it's not exactly unbreakable encryption, but hey, it's a fun, quirky tool!
How to Play
Type your secret message.Choose an emoji or text to act as a carrier.Copy and paste the encoded result into your chosen platform (test the copy/paste carefully!).

It only seems to work if you copy and paste the spaces around the emoji, which seems important to mention.
funny enough first thing that comes to mind is "can this be used to load resumes with key words that AI readers would notice but not mess up the flow of the resume itself"
Sending the coded emoji in an email erases the code
Neat toy, but not secure in any way pasting into a hex editor shows all the characters, and it's just an extremely simple substitution cipher. and the emoji doesnt contain anything, it's the blank space around it that you need to select.
I wouldn't.

Frequently Asked Questions
Does this method work reliably across all platforms and apps?
While designed for broad compatibility, some platforms might alter or remove zero-width characters; always test your encoded message beforehand.
Is this a secure way to hide sensitive information?
No, this method is not cryptographically secure. It's primarily intended for playful messaging or low-stakes secrecy, not for protecting confidential data.
