Upload a PNG image exported by QREagleStudio to extract the steganographic QR code hidden inside — invisible to the naked eye, scannable here.
Each pixel's red value changes by at most 1 out of 255 — 0.4 % — completely invisible to the human eye.
QREagleStudio embeds your QR code into the least-significant bit of each pixel's red channel. The photo looks completely normal.
Post it on social media, print it, send it via email — it looks like any other photo. Only the original PNG retains the hidden data.
Upload the original PNG to this page. The server reads the hidden pixel bits and reconstructs the QR code for scanning.
The extracted QR appears on screen. Point your phone camera at it — iOS reads it instantly, no app required.
⚠️ Important: PNG only
JPEG, WebP re-compression, WhatsApp, and iMessage image compression all alter pixel values and permanently destroy the hidden data. Always share the original PNG file.
