STEGG
Secret Messages. Hidden in Plain Sight.
Hide any message inside any image using steganography. The image looks completely untouched — only Stegg can reveal what's hidden inside.
Features
Everything you need for digital privacy
Hide Messages in Images
Pick any photo, type your secret message — Stegg hides it in the pixels using LSB steganography. The image looks completely identical.
Extract Hidden Messages
Got a stegged image? Crack it open and reveal the hidden message inside. Only Stegg knows how to read the invisible data.
Image in Image
PROHide an entire photo inside another photo. The cover image looks perfectly normal while concealing a secret image inside.
Password Protection
Encrypt your secret messages with a password. Even if someone discovers the hidden data, they can't read it without the key.
Resilient Mode
Uses 2 bits per channel instead of 1 for more robust encoding. Your hidden data survives mild compression and quality loss.
Invisible to the Eye
Stegged images are visually identical to the originals. No one can tell your photo carries a hidden message just by looking at it.
How It Works
Three simple steps
Choose an Image
Pick any photo from your camera roll. Larger images can hold more data — a 1000×1000 image fits roughly 60,000 words.
Type Your Secret
Write your message and optionally set a password. Stegg compresses and encrypts it before embedding.
Share Safely
Save or share the stegged PNG. Send as a file attachment, via AirDrop, email, or cloud storage to preserve the hidden data.
SECRET INSIDE
The image looks identical.
The message is invisible.
