About this app

UploadImages.org is private image sharing done right.

Most image hosts can see every photo you upload. We can't - and we proved it by design.

YOUR PHOTOS, ENCRYPTED ON YOUR DEVICE

Before a single byte leaves your phone, the app encrypts your image with AES-256-GCM, the same authenticated encryption used by banks and intelligence agencies. The decryption key never reaches our servers. It lives inside the share link you generate, in the URL fragment that browsers never transmit.

The server only sees ciphertext - random bytes it cannot read, even if compelled.

HOW IT WORKS

- Pick a photo from your gallery
- The app encrypts it locally on your device
- Encrypted data uploads over TLS 1.3
- You get a short share link with the key in its fragment (#)
- Send the link to anyone you want
- They open it, the image decrypts in their browser, they see your photo
- Without the link, the photo is gibberish - even to us

The "#" fragment of the URL is never sent to our server during normal navigation. That's not a workaround - that's how the web is designed. We literally cannot decrypt your photos, and nobody can force us to.

FEATURES

- End-to-end encrypted (AES-256-GCM + HMAC-SHA256 + HKDF-SHA256)
- Post-quantum protection at rest (ML-KEM-1024, ML-DSA-87, SLH-DSA-SHAKE-256s)
- No account required - no email, no phone, no name
- No ads. No analytics. No third-party trackers. No data harvesting.
- Encrypted vault to save your share links on-device
- EXIF metadata stripped before upload - your GPS coordinates never leak
- Open share links from any modern browser
- Works alongside the web version at uploadimages.org

PRIVACY

What we collect: nothing personal.
What we can see: ciphertext.
What we can recover if you lose your link: nothing.
What we sell to advertisers: nothing.

If a court orders us to hand over your photo, we can hand over only encrypted bytes. The key isn't ours to give.

USE CASES

- Send sensitive screenshots without leaving copies in cloud galleries
- Share medical photos with your doctor over chat
- Send IDs or documents safely
- Share family photos without uploading to ad-tracked services
- Send images that would be embarrassing if breached
- Anything you'd rather not hand to a server you don't control

WHAT THIS APP IS NOT

This app does not invent its own cryptography. It uses standard primitives - AES-256-GCM, HMAC-SHA256, HKDF - that have been studied for decades by professional cryptographers. We do not claim to defend against nation-state adversaries with physical access to your unlocked phone. We do claim that the server we operate cannot see your photos and is designed so we can never be made to.

OPEN SOURCE & AUDITABLE

The cryptographic code runs in your browser when you view a shared link. You can inspect it via developer tools. The mobile app uses the same OpenSSL primitives that protect HTTPS itself.

UploadImages.org - your photos, your keys.
