Generate QR codes and barcodes for URLs, text, products, and more.
Our free QR Code and Barcode Generator lets you create professional-quality codes for URLs, text, contact info, WiFi credentials, and product barcodes — all directly in your browser with no uploads, no accounts, and no fees. Generate, customize, and download your codes in seconds.
Whether you need a QR code for a business card, a barcode for inventory management, or a WiFi sharing code for your home network, this tool covers every common use case with a clean, intuitive interface.
A QR code (Quick Response code) is a two-dimensional matrix barcode that can store a wide variety of data types — URLs, plain text, contact information, phone numbers, SMS messages, email addresses, and even WiFi network credentials. Smartphones can scan QR codes instantly using their built-in cameras, making them one of the most versatile and widely used data-sharing formats in the world.
A barcode is a one-dimensional representation of data using parallel lines of varying widths. Barcodes are the standard for product identification in retail, logistics, healthcare, and manufacturing. Common formats include CODE128 (general purpose), EAN13 (retail products in Europe), UPC (retail products in North America), and CODE39 (industrial and government applications).
This tool supports both formats with full customization options including size, colors, error correction levels, and barcode dimensions — giving you complete control over the appearance and functionality of your generated codes.
For QR codes that will be printed at small sizes (such as on business cards), use a higher error correction level like "High" (30%). This makes the code more resilient to damage, smudging, or partial obstruction while still being scannable. For digital-only use where the code will always be displayed cleanly, "Medium" (15%) is a good balance between data density and reliability.
When customizing QR code colors, ensure there is sufficient contrast between the foreground and background colors. Dark foreground on light background is the most reliable combination. Avoid using similar shades or low-contrast color pairs, as these can cause scanning failures on some devices. Always test your custom-colored QR code with multiple devices before printing or publishing.
For barcodes, make sure your data matches the requirements of the selected format. EAN13 requires exactly 13 digits, UPC requires 12 digits, and ITF14 requires 14 digits. CODE128 is the most flexible format and accepts any combination of letters, numbers, and symbols, making it the best choice when you're unsure which format to use.
Many QR code generators online add watermarks to downloaded images, require you to create an account, or limit the number of codes you can generate for free. Our tool has none of these restrictions — generate as many codes as you need, download them in full quality, and use them for any purpose without attribution requirements.
The combination of QR code and barcode generation in a single tool is rare among free online utilities. Most tools specialize in one or the other, requiring you to use multiple websites. Here, you get both in one place with a consistent, easy-to-use interface.
All generation happens locally in your browser, which means your data — including WiFi passwords, contact details, or proprietary product codes — never leaves your device. This is a significant privacy advantage over cloud-based code generators that process your data on their servers.
Your privacy is our priority. All processing happens entirely in your browser using JavaScript. No files, data, or inputs are ever uploaded to any server. Everything stays on your device, making this tool completely safe to use with sensitive content.
