QR code reader
Use QR code reader to decode a QR image and inspect its text before acting. Follow file-selection steps, improve readability, and review destination limits.
QR code reader
QR code reader reads a QR code from an image file and displays the decoded text. Use it when a code appears in a screenshot or document and you want to inspect its content first. Select an image containing a clear code rather than expecting the form to read a printed object automatically.
How to use QR code reader
- Prepare an image containing the whole QR code and its surrounding margin.
- Choose the image in the file field and wait for the decoded result.
- Read the returned text carefully and copy only the information you need.
A practical example
A QR code on an event graphic may contain a registration address. Decode the screenshot, inspect the hostname and path, and compare them with the organizer’s known destination. Reading the text first lets you notice an unexpected address without treating successful decoding as permission to visit it or enter personal details.
Limitations
Blurring, cropping, glare, or a very small code can prevent recognition. This page is configured for QR codes, while other barcode families have a separate reader. Decoding reveals a payload but does not establish the safety, accuracy, or ownership of an address or message contained inside it.
Common questions
Do I need a camera?
This workflow reads a selected image file. A screenshot or a clear photograph can provide the source without a live camera session.
Why is no data shown?
Try a clearer source with the full code visible. A failed read does not prove the image contains no QR code.

Use Barcode reader for other supported barcode families. If the payload is an address, inspect it with URL parser or check encoded text using URL decoder.
