TOTP QR Image Decoder

TOTP Toolset

Upload a QR code image to decode its contents. If it is a standard TOTP profile, you will see the secret, issuer and account, plus a direct link to the TOTP Toolset. All computation happens locally — no seed is ever sent to a server.

Decode an image

How it works

  1. Upload: select a QR code image file.
  2. Decode: the image is processed with standard decoding.
  3. TOTP Toolset: get a direct link to calculate OTPs from the QR (SHA-1 or SHA-256).
  4. Inspect: for a TOTP profile you will see the secret, issuer and account; otherwise you are told it is not a TOTP format.
