What to expect

Reads QR payloads locally from an image; Scan also supports a browser camera. Reverse reveals the stored content, not the original image or generator settings. No links are opened automatically.

Do my files leave my device?

No. Thanks to advanced file-processing technology, your files are processed directly on your device, inside your browser. OneKit does not receive your input files or results. Required public processing libraries may download when you first use the tool.
