🧠 How does it work?
🖼️
You pick a file
The file is loaded into your browser's memory — it never leaves your tab.
⚙️
Browser calculates hash
A WebAssembly program runs inside your browser and converts the image into a 64-char code called a PDQ hash.
📤
Only the hash is sent
Only that short code is sent to our server. The image itself stays on your device.
🔧
