QR Code Scanner

The QR Code Scanner instantly decodes the hidden content of any QR code — from an uploaded image or screenshot, a pasted picture, or your live camera. Unlike most online scanners, it reads the code entirely inside your browser, so your image and camera feed are never uploaded to a server. It also recognises what the code actually contains — a website link, a Wi-Fi login, a saved contact, an email, a phone number, a location, or plain text — and shows it in a clear card with the right one-tap action.

How to Scan a QR Code

1. Choose your method: Pick Upload image to read a saved photo or screenshot, Camera to scan a physical code in front of you, or Paste to read a QR image sitting on your clipboard.
2. Add the QR code: Drag and drop an image (or click to browse), press Ctrl+V to paste, or point your camera at the code and hold steady. You can even drop several images at once.
3. Read the result: The decoded content appears in a smart card that identifies the data type — link, Wi-Fi, contact, email, phone, SMS, location or text.
4. Take action: Open the link, copy the text, reveal and copy a Wi-Fi password, save a contact as a .vcf file, or add an event to your calendar.

What Types of QR Codes Can It Read?

QR codes can store far more than web links. This scanner detects the most common payload formats and presents each one in a tailored way:

Why Scan in Your Browser?

Many QR scanning websites upload your photo to their servers to decode it. This tool does the opposite: the decoding library runs locally in your browser and reads the pixels directly from a hidden canvas. That means:

• Privacy: Your image and camera stream stay on your device — nothing is ever sent, stored or logged.
• Speed: There is no upload or round-trip, so results appear the instant the code is recognised.
• Works offline: Once the page has loaded, scanning a saved image keeps working even without a connection.
• No install: There is no app to download and no account to create.

QR Code vs Barcode

A traditional barcode is one-dimensional — a row of vertical lines that stores a small number, usually a product ID. A QR code (Quick Response code) is two-dimensional, storing data in a grid of black and white squares. Because it uses both dimensions, a QR code holds far more — hundreds of characters of text, full URLs, Wi-Fi logins and contact details — and can still be read from any angle thanks to the three large square "finder" patterns in its corners. QR codes also include error correction, so they scan reliably even when partly dirty, creased or obscured.

Tips for a Successful Scan

• Fill the frame: Move closer or crop so the QR code takes up most of the image.
• Keep it sharp: Avoid motion blur — hold your phone steady and let the camera focus.
• Light it evenly: Strong glare or deep shadow across the code can hide squares. Aim for even lighting.
• Mind the contrast: Codes read best when the dark squares are clearly darker than the background.
• Straighten it: A roughly flat, front-on view scans more reliably than a steep angle.

Is It Safe to Scan QR Codes?

Scanning a QR code only reveals the text inside it, so the act of scanning is safe. The real risk is what you do next. Attackers sometimes place malicious QR codes in public places ("quishing") that lead to fake login or payment pages. Because this scanner shows you the full decoded link before you open anything, you can check it first. As a rule, never enter passwords or payment details on a site you reached from an unexpected QR code, and be cautious with shortened links whose true destination you cannot see.

Frequently Asked Questions

Is this QR code scanner free and private?

Yes. The scanner is completely free and runs entirely in your web browser. Your image and camera stream never leave your device and are never uploaded to any server, so scanning stays private. There is no sign-up, no watermark and no app to install.

How do I scan a QR code from an image?

Open the Upload image tab, then drag a photo or screenshot onto the drop area or click to browse for it. You can also paste an image from the clipboard with Ctrl+V. The tool decodes the QR code and shows the result immediately, and it can read several images in one batch.

Can I scan a QR code with my camera?

Yes. Open the Camera tab and allow camera access, then point your phone or laptop camera at the QR code. The scanner reads the code automatically as soon as it is clearly in view. Camera scanning needs a secure HTTPS connection, which this page uses.

What kinds of QR codes can it read?

It reads standard QR codes containing website links, Wi-Fi network logins, contact cards (vCard), email addresses, phone numbers, SMS messages, map locations and plain text. Each type is shown in a tailored card with the right action, such as Open link or Save contact.

Why won't my QR code scan?

Make sure the whole QR code is visible, in focus and well lit, with good contrast between the dark and light squares. Very blurry, glare-covered, damaged or extremely low-resolution codes may fail. Try a sharper photo, move closer, or crop the image so the code fills more of the frame.

Can I scan many QR codes at once?

Yes. Select or drop several images at once, or use a screenshot that shows more than one code. Every code found is listed with the image it came from. Copy all copies every result, and Download all (CSV) saves the whole batch as a spreadsheet file.

Is it safe to scan an unknown QR code?

Scanning only decodes the text inside the code, so reading it is safe. The risk is in what you do next. Always check a decoded link before opening it and never enter passwords or payment details on a site you reached from an unexpected QR code. This tool shows the full link so you can review it first.
