Was QR Code Decoder useful?
QR Code Decoderとは？
Read the text or URL hidden in any QR code image. Drop in a screenshot, a photo, or a saved QR, and get the decoded payload.
The tool detects the payload type and offers the right follow-up: open a URL, compose an email, or copy the Wi-Fi credentials. The whole process runs locally — the image never leaves the page.
使い方
-
Choose an image
JPG, PNG, or WebP. Screenshots and photos both work.
-
See the result
The decoded text appears with a label for the payload type (URL, email, Wi-Fi, vCard, plain text).
-
Copy or open
Copy the text, or open the URL directly. Wi-Fi and vCard payloads get a copy-credentials button.
使用例
Decode a screenshot of a QR code
A screenshot from a chat, an email, or a website often contains a QR code. Drop the screenshot in and get the URL or text in one click.

結果： Detected: URL. Decoded: "https://example.com/signup". One click to copy or open.
Read a Wi-Fi QR from a sticker or a card
Many routers, cafes, and offices print a QR code that connects a phone to Wi-Fi without typing the password. Drop the QR in and get the network name and password ready to copy.

結果： Detected: Wi-Fi. Network: CoffeeShop. Password: hello123.
