QR Code Generator

QR codes are a practical way to move users from physical or static media into digital actions like visiting a URL, joining WiFi, sending email, or opening app deep links. This generator helps you create codes quickly with adjustable size and error correction so they scan reliably across devices. When encoding links with query parameters, sanitize special characters first with the URL Encoder. If you need to embed downloaded QR images into markup or payloads, use Image to Base64 or Base64 Encoder depending on your workflow.

How to Use

1. Enter the content you want the QR code to contain.
2. Select settings such as dimensions and error correction level.
3. Review the preview and test scan from another device.
4. Download the final image for print or digital distribution.

For URLs, include the full protocol (https://) to reduce scanner ambiguity. For WiFi, verify network type and password formatting before distribution.

Key Features

• Supports multiple data types including links, text, phone, email, and WiFi payloads.
• Adjustable output size for screens, handouts, labels, and posters.
• Error correction options to improve scan tolerance after minor damage.
• PNG download ready for websites, print files, and internal documentation.

A small design tweak can strongly affect scan rate. High contrast, sufficient quiet zone, and realistic print size usually matter more than decorative styling.

Common Use Cases

• Marketing posters that direct to campaign landing pages.
• Product packaging with support docs or setup instructions.
• Restaurant menus and event materials for touchless access.
• Office onboarding cards that share secure guest WiFi details.

Before generating large batches for print, test links on iOS and Android and verify any special characters are safely encoded with the URL Encoder. If your publishing system needs inline image strings, convert output files through Image to Base64.

Technical Details

QR codes store data in a matrix of modules with built-in error correction (L, M, Q, H). Higher correction increases resilience but also increases symbol density, which may require larger output dimensions for consistent scanning. Content format matters: long raw URLs with unescaped characters can create scanning or routing issues, so preprocessing with URL Encoder often improves reliability.

Downloaded images are commonly PNG for broad compatibility. If you need to transmit the image as text within JSON, CSS, or HTML templates, convert the binary output using Base64 Encoder or Image to Base64, depending on whether you start from text or file input.

FAQ

Can I create a QR code for a website URL?

Yes. Paste a full URL and generate a scannable QR code that opens the link directly on compatible devices.

What error correction level should I choose?

Use medium for general digital sharing and high for printed surfaces that may get scratched or partially covered.

Why does a QR code fail to scan on some phones?

Low contrast, small print size, crowded data, or missing URL encoding can reduce scan reliability across camera apps.

Can I convert my QR image into Base64?

Yes. After downloading the PNG, you can convert it to Base64 for embedding in HTML, CSS, or API payloads.
