Can anyone see the hidden message?
No. The image looks identical; only someone who knows to extract it can read the message.
Is the process private?
Yes. The hiding happens in your session and the file is deleted afterward.
How do I hide a text message inside an image?
Upload a cover image, type your secret message, and download an image that looks completely ordinary but carries the text inside.
How does the other person extract the message?
They upload the image in the same tool to extract the hidden message inside it.
Does the image change noticeably?
No. The image looks identical to the naked eye, and no one notices a message is inside.
What is the difference between hiding and encryption?
Encryption makes a message unreadable but its existence is visible; hiding conceals that a message exists at all inside an ordinary image.
