Want to create a QR code but not sure which tool to use? This guide walks you through how to generate a QR code for free, right in your browser.
What Is a QR Code?
A QR code (Quick Response Code) is a two-dimensional barcode developed by Denso Wave in 1994. Compared to traditional barcodes, QR codes can store significantly more data — including URLs, text, and contact information.
Because anyone can scan a QR code with a smartphone camera to instantly open a website, QR codes are widely used on business cards, flyers, posters, restaurant menus, and more.
How to Create a QR Code (3 Steps)
Creating a QR code is straightforward.
Step 1: Decide What Data to Embed
First, decide what information you want your QR code to contain. Common use cases include:
- URL: Link to a website or social media profile
- Text: A message or any free-form text
- Email address: Opens an email compose screen on tap
- Phone number: Initiates a phone call on tap
- Wi-Fi credentials: Share your SSID and password
Step 2: Generate the QR Code
Once you have your data ready, generate the code using a QR code tool. With sakutto's QR code generator, you can create one right in your browser.

Understanding QR Code Error Correction Levels
QR codes have a built-in error correction feature that allows them to be read even when part of the code is dirty or damaged. There are four levels:
| Level | Recoverable Data | Best For |
|---|---|---|
| L (Low) | ~7% | Digital display only (on-screen use) |
| M (Medium) | ~15% | Standard print materials (flyers, business cards) |
| Q (Quartile) | ~25% | QR codes with logos, outdoor signage |
| H (High) | ~30% | Harsh environments (factory labels, warehouse tags) |
Higher error correction levels make the QR code denser (more dots), so the code needs to be larger to remain scannable. If you plan to place a logo in the center, choose level Q or higher to compensate for the obscured area.
Tips for Designing Custom QR Codes
Customized QR codes with colors and logos are becoming increasingly common.
- Color changes: Match the foreground color to your brand
- Logo placement: Add a logo to the center so people instantly recognize your brand
- Dot styles: Switch to rounded or diamond-shaped dots for a unique look
Printing Considerations
When using QR codes on printed materials, keep these points in mind:
- Minimum size: 1.5 cm × 1.5 cm is recommended — smaller codes may be hard to scan
- Quiet zone: Leave at least 4 modules (dots) of white space around the QR code
- Resolution: Export at 300 dpi or higher for print
- Test scanning: Always test with multiple smartphones (both iPhone and Android) before printing
Use Cases
Business Cards
Adding a QR code to your business card creates a direct path to your website or social profiles. With vCard format, recipients can save your contact info with a single scan.
Flyers and Posters
Link to event details or registration forms via QR code to seamlessly bridge print and digital media.
Restaurant Menus
More and more restaurants place QR codes on tables that link to digital menus. This makes updates easy and reduces printing costs.
Summary
Creating a QR code is simple with the right tool. Keep design customization and print guidelines in mind to make the most of your QR codes.
