Hide Secret Messages in Images
Conceal private messages inside ordinary images. The image looks completely normal — but carries your hidden text. 100% processed in your browser.
About Steganography
Confileo's Steganography tool conceals a secret message invisibly inside an image. Everything runs in your browser, free and without signup, and your files are deleted automatically after processing.
Sometimes you want to send a message without anyone even knowing a message exists. Unlike encryption, which hides the content but not the fact that something is hidden, steganography conceals the message inside an ordinary-looking image.
Confileo's Steganography tool hides your secret text invisibly inside a cover image that looks completely normal; the recipient extracts it with the same tool. The process runs privately in your session and the file is deleted afterwards.

Steganography — Frequently asked questions
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.
Is this tool really free?
Yes. Every Confileo tool is free to use with no daily caps, no watermark on your output and no credit card required.
Do I need to create an account?
No. You can use the tool straight away without signing up or logging in.
Are my files safe and private?
Yes. Your files are processed for the task you requested and then deleted automatically — they are never shared or kept.
Does it work on my phone?
