QR Code Generator

A QR (Quick Response) code is a two-dimensional matrix barcode that can store various types of data including URLs, plain text, contact details, Wi-Fi credentials, and more. Originally developed in 1994 for tracking automotive parts, QR codes have become ubiquitous in daily life. When scanned with a smartphone camera or QR reader app, the encoded data is decoded and the appropriate action is triggered, such as opening a website, connecting to a Wi-Fi network, or saving a contact to your address book. QR codes use a combination of dark and light modules arranged in a square grid on a white background, with special finder patterns in three corners that help scanners detect the orientation and boundaries of the code.

Yes, this QR code generator is 100% free with no limits on how many codes you can create. There is no signup required, no watermarks added to your codes, and no premium tier to unlock features. All QR code generation happens directly in your web browser using client-side JavaScript, which means your data never leaves your device and is never transmitted to any server. You can generate and download as many QR codes as you need for both personal and commercial use without any restrictions.

This tool supports six different QR code types to cover a wide range of use cases. The Text/URL tab lets you encode any plain text or web address. The Wi-Fi tab creates codes that automatically connect devices to your network when scanned, perfect for sharing guest access without revealing your password verbally. The Email tab generates codes that pre-fill the recipient address, subject, and body of an email. The Phone tab creates callable phone number codes. The SMS tab encodes a phone number and pre-written message. Finally, the vCard tab lets you create contact cards with name, phone, email, organization, and website fields that are saved directly to the scanner's contacts.

Error correction is a built-in feature of QR codes that allows them to remain scannable even when partially damaged, dirty, or obscured. There are four levels to choose from. Level L (Low) can recover approximately 7% of lost data and produces the smallest, simplest codes ideal for digital screens. Level M (Medium) recovers about 15% and is the default choice for most general-purpose QR codes. Level Q (Quartile) can handle up to 25% data loss and is a good choice for printed materials. Level H (High) provides maximum resilience by recovering up to 30% of data, making it the best option for codes that will be placed on packaging, outdoor signage, or surfaces that may get scratched or weathered over time.

Yes, you can fully customize the foreground (module) color and background color of your QR code using the color pickers. While classic black-on-white provides the best contrast and scan reliability, you can create branded QR codes in any color combination. For optimal scanning, make sure there is strong contrast between the foreground and background colors. Dark foregrounds on light backgrounds generally work best. Avoid using similar shades or low-contrast combinations as they may cause scanning difficulties, especially in poor lighting conditions or at smaller sizes.

PNG (Portable Network Graphics) is a raster image format that stores your QR code as a grid of pixels at the exact size you selected. PNG files are ideal for web use, social media, email attachments, and most digital applications. SVG (Scalable Vector Graphics) is a vector format that stores the QR code as mathematical shapes, which means it can be scaled to any size without losing quality. SVG files are perfect for print production, large-format signage, professional graphic design work, and situations where you need the QR code at different sizes from the same file.

Absolutely. This QR code generator runs entirely in your browser using client-side JavaScript. No data is sent to any server at any point during the generation process. Your text, URLs, Wi-Fi passwords, contact information, and all other inputs remain on your device. The QR code is rendered on an HTML canvas element and the download files are created locally. This privacy-first approach means you can safely generate QR codes containing sensitive information like Wi-Fi passwords or private URLs without any risk of data exposure.

Most modern smartphones can scan QR codes directly through their built-in camera app. On iPhone, simply open the Camera app and point it at the QR code. A notification banner will appear with the decoded content. On Android devices, open the Camera or Google Lens app and aim at the QR code. If your phone does not support native QR scanning, you can download a free QR code reader app from your device's app store. For best results, ensure the entire QR code is visible in the camera frame, hold your phone steady, and make sure there is adequate lighting.
