QR Code Reader: read QR codes from images
A QR code is available as an image, but you did not scan it? This QR code reader reads the content of a QR code directly from an uploaded image, without needing your phone or a separate app. Select an image and the tool decodes the code immediately in your browser. Suitable for screenshots, photos, and image files that contain a QR code.
You upload an image file in PNG, JPG, or WebP format and instantly get the decoded content. That can be a URL, text, a phone number, an email address, or data such as Wi-Fi credentials. The content is shown in the browser and can be copied with one click.
How reading works
The tool uses a software solution for QR code detection that runs directly in your browser. The library analyzes the image data, recognizes the position pattern of the QR code, corrects possible distortions, and decodes the stored bytes. Thanks to error-correction mechanisms, many QR codes remain readable even when they cover part of the image or are slightly damaged.
- Select an image with a QR code, for example a screenshot or a photo.
- The code is decoded locally in your browser.
- The result appears as text and can be copied.
- No upload, no server contact, your data stays with you.
What it can and cannot do
The QR code reader suits all common QR codes on screenshots, photos, and image files. The clearer and larger the code in the image, the more reliably reading works. Very small, blurred, or heavily distorted codes can reach the limits of detection. If you need a code to scan directly with your camera, you can create one with the QR code generator on this site.
Frequently asked questions
Which image formats are supported?
Common image formats such as PNG, JPG, and WebP are supported. As long as the QR code is clearly visible in the image, decoding works reliably.
Is reading a QR code safe?
Yes. Decoding runs entirely in your browser and without upload. Your image file never leaves your device and is not sent to a server.
What can be stored in a QR code?
QR codes can store text, URLs, phone numbers, email addresses, Wi-Fi credentials, or other electronic data. The tool shows the decoded content as text.
Why is my QR code not detected?
This usually happens with very small, blurred, unsharp, or heavily distorted codes. Crop the QR code as closely as possible and ensure a clear, well-lit image, and the detection rate rises significantly.
Does the tool recognize damaged QR codes?
Many QR codes have error correction, so they remain readable even when parts are damaged or image areas cover the code. The reader uses this correction as far as technically possible.
