Free Online QR Code Scanner

QR Code Scanner is a free online QR code scanner that reads QR codes with your camera or from an image, right in your web browser. There is no app to install, no download, no account, and nothing is uploaded: every code is decoded on your own device. Point your phone, tablet, or laptop camera at a code, or open a photo or screenshot, and the result appears in a moment. Whether you need a quick QR scanner on your phone, a QR code scanner for PC, or a way to read a QR code from an image, this page does it for free.

What Is a QR Code Scanner?

A QR code is a square, two-dimensional barcode that stores a short piece of text. Usually it is a web address, but it can also be Wi-Fi login details, a contact card, a phone number, or a calendar event. Developed in Japan in 1994 to track car parts, QR codes now appear on menus, tickets, posters, packaging, and invoices. A QR code scanner, also called a QR code reader or QR code decoder, finds that pattern in a camera view or an image and turns it back into the text it holds.

Phone cameras usually include a basic scanner, but it can't read a code that is already on your screen, and most laptops have no scanner at all. An online QR code scanner closes those gaps. It runs in any modern browser, works with any camera, and reads codes straight from image files, so a QR code reader online is always one tap away.

How to Scan a QR Code with Your Camera

Scanning with your camera takes only a few seconds:

1. Open the QR code scanner at the top of this page and choose Camera.
2. Select Start camera and allow camera access when your browser asks.
3. Hold the QR code inside the frame, about 15 to 30 cm (6 to 12 in) from the lens.
4. Check the result and choose an action, such as Open link or Copy.

On phones and tablets the scanner starts with the back camera. If your device has several cameras, pick another one from the list, and turn on the flashlight in dim light when your device supports it. The scanner pauses as soon as it finds a code, so there is no shutter button to press. Our guide to scanning QR codes on any device covers iPhone, Android, Windows, and Mac step by step.

Scan QR Code from Screenshot

Sometimes the code is already on your screen: in a screenshot, a PDF ticket, an email, or a photo someone sent you. Switch to Image and the page becomes a QR code image scanner. Choose a file, drag it onto the scanner, or paste it with Ctrl+V or ⌘V, and the code is read in a moment. If you were looking for a QR code scanner from image files rather than a live camera, this is it.

Scan QR Code from Picture in Your Gallery

You can scan a QR code from a picture you saved weeks ago as easily as from a fresh screenshot. On a phone, the tool doubles as a QR code scanner from gallery photos: tap Choose image and pick a picture from your photo library. Each image is tried at several sizes with extra white space added, which rescues many small or tightly cropped codes. The Scan QR Code from Image page has more tips for pictures that won't read.

Free QR Code Scanner Without App or Download

This is a free QR code scanner in the simplest sense: no price, no trial, no sign-up, no scan limit, and no watermark. It is a QR code reader, free for everyone, and a true QR code scanner: no download, no installation, and no browser extension. It only asks for camera access when you choose to use the camera.

That makes it a handy QR code reader without app installs, ideal for shared or work computers where installing software isn't allowed, and for phones that are short on storage. Open the page, scan, and close the tab. If you need a QR code scanner online, free and ready in seconds, bookmark this page.

QR Code Scanner for PC and Laptop

Phones have scanning built in, but computers usually don't. This page is a QR code scanner for PC and Mac that needs nothing but a browser: open it in Chrome, Edge, Firefox, or Safari, select Start camera, and hold the code up to your webcam. It also works as a QR code scanner for laptop webcams, with a camera picker for switching between a built-in camera and a USB one. Unlike apps that only run on phones, it is a QR code scanner with camera support on any device that has a webcam.

Laptop cameras often have fixed focus, so hold printed codes a little further away, or photograph the code with your phone and scan the photo instead. When a code is on your own screen, take a screenshot (Win+Shift+S on Windows or ⌘+Ctrl+Shift+4 on a Mac) and paste it straight into the scanner.

A QR Code Decoder That Understands What It Reads

A good QR code decoder does more than show raw text. This one recognizes the common QR code formats and offers the right action for each. Links show the full address and domain before you open them. Wi-Fi codes show the network name and security type, with the password hidden until you reveal or copy it. Contact cards in vCard or MECARD format can be saved to your address book, and calendar events can be added to your calendar. Email, phone, and text message codes open the matching app on your device, map locations open in OpenStreetMap, and anything else is shown as plain text that you can copy.

Every result also shows the raw content, which makes this an easy way to decode QR code online, free, and see exactly what a code contains. The Wi-Fi QR code guide explains how to join a network from a code on any device.

How the QR Code Detector Keeps Your Scans Private

Some QR scanner online services upload your picture to a server to decode it. This one doesn't. When your browser has a built-in barcode detector, the page uses it. Otherwise, a fast open-source QR code detector runs in a background worker on your device, so the page stays smooth while it reads. Camera video is processed frame by frame in memory and then discarded, and images you choose never leave your device. Recent results are saved only in this browser, and only while history is switched on. There are no accounts, cookies, ads, or analytics. The privacy policy explains the details.

Scan QR Codes Safely

A QR code can lead anywhere, and scammers know it. Fake codes stuck over real ones on parking meters, restaurant tables, and posters can send you to convincing copies of login or payment pages, a scam known as quishing. This free online QR scanner helps you stay in control: nothing opens automatically, the full address and domain are shown first, links that don't use HTTPS are flagged, and unusual link types such as javascript: are shown as text and never opened.

Before you choose Open link, read the domain carefully, be wary of codes that ask you to log in or pay, and never enter a password on a page you reached from an unexpected code. The QR code safety guide covers the warning signs in more detail.

What to Do When a QR Code Won't Scan

Most failed scans have a simple cause. Move a little closer or further away so the code fills the frame, hold still for a second, and tilt glossy paper or screens to remove glare. Make sure the whole code is visible, including a thin blank margin around it. If the camera keeps struggling, take a sharp photo and scan it in Image mode, which tries several sizes and also reads light-on-dark codes. The troubleshooting guide explains every error message and how to fix it.
