When to use QR code scanner
These workflows use the formats and behavior supported by this implementation.
Read a saved QR image
Choose a clear saved image with enough space around the QR code. Small, blurred or damaged codes may not decode.
Inspect a link before opening it
Read the decoded URL as text and inspect its destination yourself. Scanning does not navigate to the address.
Recover encoded plain text
QR codes can store text other than links. Copy or download the decoded content without interpreting it as an instruction.
What the output contains
Keep the output format and conversion policy in view.
Decoded QR text from a local image. Decode image pixels locally with ZXing restricted to the QR format.
Compare the result with the original before replacing a source file. Conversion limits are listed below.
Supported input and limits
