Connect the Physical to the Digital: The All-in-One Code Creator

In a contactless world, QR codes and barcodes are the essential bridges between physical items and digital data. Whether you are a retailer needing UPC labels for your products, a restaurant replacing paper menus with QR scans, or a warehouse manager organizing inventory, our QR & Barcode Generator creates high-resolution, scannable codes instantly. No software installation required.

Which Code Format Do You Need?

Choosing the right format is critical for scannability. This tool supports the four most important standards:

  • QR Code (2D): The most versatile format. It can hold URLs, plain text, or even WiFi credentials. Perfect for marketing materials and business cards because smartphones can scan them natively.
  • Code 128 (Logistics): The gold standard for shipping and inventory. It is a high-density alphanumeric code that can store any letter or number. Use this for internal tracking labels or shipping manifests.
  • UPC-A (US Retail): The 12-digit barcode found on almost every product sold in the United States and Canada. If you are selling on Amazon or in a grocery store, this is the standard.
  • EAN-13 (Global Retail): The European version of the UPC. It uses 13 digits and is the standard for retail products sold internationally.

Feature Highlight: The WiFi QR Code

Stop asking guests to type in long, complicated WiFi passwords. Select "QR Code" and type your network details in this format: WIFI:S:MyNetworkName;T:WPA;P:MyPassword;;. When guests scan this image, their phone will automatically prompt them to join your network.

Design & Scannability Tips

A pretty code is useless if it doesn't scan. Follow these rules to ensure reliability:

  • High Contrast is King: Always use a dark code on a light background (e.g., Black on White). While our tool allows you to change colors (like Red or Blue), never invert the colors (White code on Black background), as many scanners cannot read them.
  • Quiet Zone: Always leave a margin of white space around the code. If you print text or images too close to the bars, the scanner will get confused.
  • Size Matters: For QR codes, the minimum recommended print size is 2cm x 2cm (0.8 inches). Anything smaller may be unreadable by older phone cameras.

Frequently Asked Questions

Do these codes expire?

No. These are "Static Codes." The data is embedded directly into the image pixels. As long as your website URL doesn't change, the QR code will work forever. There are no monthly fees or scan limits.

Can I print these on labels?

Yes. The generator produces high-clarity images. You can download the image and paste it into a Word document or label printer software (like for Avery labels) to print seamlessly.
