About QR Code Decoder
Upload or paste an image to scan and read QR code contents instantly in your browser.
QR Code Decoder reads any QR code image without sending it to a server. Drop a file, paste a screenshot or drag a photo straight from your desktop, and the scanner detects the code, corrects for a slight tilt and prints the decoded payload in plain text within a second. It handles the usual content types, including web links, contact cards, wifi network details and plain messages, and it keeps a short history of earlier scans so you can copy a result you already dismissed. Damaged or low contrast codes are retried at a higher sensitivity before the tool reports failure, which helps with photographed receipts and faded posters. Everything runs in your browser, so the image stays on your device, and decoding works offline once the page has loaded.

Frequently Asked Questions
What can I do with the text QR Code Decoder returns?
Copy it with one click, open a decoded link in a new tab, or export the whole scan history as a list. Wifi payloads are split into the network name and password so you can type them into a phone, while contact data breaks out into separate fields ready for pasting. Nothing stays behind once you close the tab.
