Turn any link or text into a QR code
About the QR Code Generator
QR codes are those square, pixelated barcodes you scan with a phone camera to open a link, save a contact, or pull up a menu. They were invented in Japan in 1994 for tracking automotive parts and have since spread into nearly every corner of everyday life, from restaurant tables to event tickets to product packaging.
Creating a QR code used to require specialized software or a paid service. Now it takes about five seconds. You type in a URL, a piece of text, an email address, or any other content, and the generator produces a scannable code immediately. You can download it as an image and use it anywhere you need.
Privacy is worth noting here. This QR code generator works entirely in your browser. The content you encode is not sent to any external server or stored anywhere. The QR code image is created locally on your device, which means sensitive links or private text stay private.
QR codes work by encoding data as a pattern of black and white squares arranged in a grid. Built-in error correction means they can still be scanned even if part of the code is obscured, dirty, or slightly damaged. There are four levels of error correction, and the higher the level, the more redundant data is stored, which also increases the visual complexity of the code.
Common uses include linking printed materials to websites, sharing Wi-Fi credentials, directing customers to payment pages, adding app download links to packaging, and providing contact information at events. Any context where typing a URL is inconvenient or error-prone is a good candidate for a QR code.
How it works
- Type or paste the content you want to encode, such as a URL, plain text, or email address.
- The QR code generates automatically or after you click a generate button.
- Preview the code on screen and test it with your phone camera to confirm it works.
- Adjust size or error correction level if those options are available.
- Download the QR code as a PNG or SVG image for use in print or digital materials.
What you'll learn
- QR codes were invented in 1994 in Japan for tracking parts in automotive manufacturing.
- They can encode URLs, plain text, phone numbers, email addresses, and other data types.
- Error correction lets QR codes remain scannable even when partially damaged or covered.
- Higher error correction levels make codes more resilient but also more visually complex.
- This tool generates QR codes entirely in your browser without sending data to any server.
- QR codes are scannable by the built-in camera app on most modern smartphones.
FAQs
- What can I encode in a QR code?
- URLs are the most common use, but you can also encode plain text, email addresses, phone numbers, SMS messages, and other structured formats depending on the tool's supported input types.
- Can anyone scan my QR code?
- Yes. A QR code is not password protected by itself. Anyone with a smartphone camera can scan it and access whatever content it encodes, so do not use it for anything you want to keep private.
- How do I scan a QR code?
- Open your phone's camera app and point it at the code. Most modern smartphones detect and scan QR codes automatically without needing a separate app.
- Does the content I enter get sent to a server?
- Not with this tool. The QR code is generated locally in your browser, so your content stays on your device and is never transmitted or stored externally.
- What is error correction and do I need to worry about it?
- Error correction determines how much of the code can be damaged or covered while still scanning correctly. For most uses the default level is fine. Use a higher level if you plan to print the code on rough surfaces.
