機能紹介
The QR Code Decoder tool lets you quickly extract URLs, text, and other data from QR codes by uploading an image or scanning with your camera. All decoding runs in your browser, so your codes stay private.
このツールを使うタイミング
Use this tool whenever you need to read the content of a QR code: checking the real target behind a QR link, extracting text from printed labels, or verifying that generated codes contain the right data.
使い方
Upload or scan a QR code
Either upload an image file containing a QR code, or enable your camera and point it at a QR code.
Let the tool analyze the image
The tool decodes the QR code directly in your browser using canvas processing and displays the result.
Review the decoded content
Read the extracted URL or text, and copy it into your browser, notes, or other tools.
使用例
Checking a QR campaign link
Scan or upload a QR from a flyer to confirm that it points to the correct landing page before printing thousands of copies.
