How do I scan a QR code on a computer?
Open this page, allow camera access and hold the code up to the webcam. If you have the code as an image or screenshot, drop or paste it instead; no camera is needed.
Scan a QR code with your camera or an image
Read any QR code, and check the link before you open it.
Or scan an image
Your files never leave this device.
Read a QR code with your phone or laptop camera, or from a photo or screenshot. The decoded content is shown first, so you can check a link before opening it, copy a Wi-Fi password or save a contact. Decoding happens on your device; the camera image is never uploaded or recorded.
How to use
- Allow camera access, or drop a photo or screenshot.
- Point the camera at the QR code.
- Read the content and check where a link goes.
- Copy it or open it.
Frequently asked questions
How do I read a QR code from an image?
Drop the picture here or paste a screenshot with Ctrl+V. The tool finds every QR code in the image and shows the content of each one.
Is it safe to scan a QR code?
Scanning itself is safe; the risk is opening a link you did not expect. This scanner shows the full address first and highlights links that look unusual, so you can decide before opening anything.
Why does the page ask for camera permission?
Browsers require permission before any site can use the camera. The video stays on your device, is only used to find the code, and stops as soon as you leave or close the scanner.
What should I do if a QR code will not scan?
Move closer so the code fills the frame, add light, hold the phone steady and avoid glare. Damaged, very small or low-contrast codes may need a sharper photo taken closer.
Can it read Wi-Fi and contact QR codes?
Yes. Wi-Fi codes show the network name and password, contact codes show the name, phone and email, and links show the full address before you open them.
How do I check a QR code before opening it?
Allow camera access and point the camera at the code, or drop a photo or screenshot. The decoded content is shown first, so you can read the full address of a link before you open it. Links that look unusual are highlighted. Take a moment with the domain name: does it match the company you expect?
How do I read a code from a screenshot or a photo?
Paste a screenshot with Ctrl+V or drop the file, and the page finds every QR code in the image, not just the first, and lists each one. That is useful for a flyer with several codes. For a photo, take it straight on, close enough that the code fills most of the frame, and avoid glare. A damaged, tiny or low-contrast code may need a sharper photo taken from closer.
What can be inside a QR code?
More than links. A Wi-Fi code shows the network name and password, which is the quickest way to recover a password you once shared with a Wi-Fi QR code. A contact code shows the name, phone and email you would save, the kind of thing a vCard QR code holds. Plain text, email addresses and phone numbers are shown as they are.
How do I spot a suspicious code, and what do I do with my own?
Scanning is safe; the risk is what you open afterwards. Be careful with codes stuck over another sticker, codes that ask for a payment or a login, and links that use a different name from the company they claim to be. When in doubt, type the official address yourself.
If a code of your own will not read, make it again with the QR Code Generator using higher contrast and a shorter link, then test it here. If you must share a screenshot that contains a code you want to keep private, cover it with Blur Image first. The live camera needs an HTTPS page, and barcodes other than QR codes are not read.

Use it in your AI assistant
Image recognition often misreads QR codes. With the local MCP server, the read_qr tool lets an assistant decode QR codes in image files on your computer exactly, for example in a folder of screenshots.
