Stesh

Stesh hides secret text messages inside ordinary photos — and nothing looks visibly altered.

Using steganography, Stesh tucks an encrypted message into the pixels of a PNG image. The picture looks completely normal: you can message it, post it, or save it, and the secret rides along invisibly. Only someone using Stesh on the right image can reveal what's inside.

Everything happens on your device. Stesh has no servers, no accounts, no ads, and no tracking of any kind. Your photos and messages never leave your phone.

HOW IT WORKS

• Pick a photo from your gallery, or snap a new one

• Type your secret message

• Optionally lock it with a password

• Stesh encrypts the message and weaves it into the image

• Share the image like any other — the secret travels with it

• No ads, no analytics, no third-party SDKs

• Every message is encrypted with AES-256 before it touches a pixel

SECURITY DISCLAIMER:

Messages hidden with Stesh could be detected using advanced steganography-decoding methods. Messages that are saved without a password are only obfuscated — perfectly fine for fun and casual privacy. For anything that truly matters, set a password so that the message can only be opened by someone who knows it. No method of hiding data is perfectly undetectable, so please don't rely on Stesh where discovery could put you at risk.

Stesh is free. Send secret notes via pictures to friends, or keep your photos as confidential notebooks — you secure them by hiding them nonchalantly in plain sight. Just Stesh It!
