What This Tool Does
The QR Code Generator creates scannable QR codes from any text or URL. You can customize the size, color, error correction level, and even add a logo overlay. The finished QR code can be downloaded as a PNG or SVG file.
QR codes are used across marketing, events, restaurants, packaging, and retail to give people instant access to digital content by scanning with their phone camera. This tool generates QR codes entirely in your browser — no data is sent to any server.
Common Use Cases
- Adding a scannable link to business cards, flyers, or posters that directs to your website or portfolio.
- Creating QR codes for restaurant menus that link to a digital menu page.
- Generating event check-in codes for conferences, workshops, or meetups.
- Placing QR codes on product packaging that link to setup guides or warranty registration.
- Sharing Wi-Fi network credentials via a scannable QR code at your office or venue.
- Linking printed marketing materials to online landing pages with UTM-tagged URLs for tracking.
How to Use This Tool
- Enter the text or URL you want to encode in the input field.
- Choose a size: Small (200px), Medium (300px), or Large (500px).
- Select an error correction level — higher levels allow the QR code to remain scannable even if partially obscured.
- Optionally change the foreground color and upload a logo to overlay on the center of the QR code.
- Preview the QR code in real time, then download it as PNG or SVG.
Best Practices and Tips
- Always test your QR code with a phone camera before printing or distributing it.
- Use High (H) error correction if you add a logo overlay — this ensures the code remains scannable despite the covered area.
- Keep URLs short. Shorter content produces simpler QR codes that are easier to scan, especially at small sizes.
- Ensure sufficient contrast between the QR code and its background. Dark codes on light backgrounds scan most reliably.
- When printing, make sure the QR code is at least 2×2 cm (about 0.8×0.8 inches) for reliable scanning.
- Avoid placing QR codes on highly reflective surfaces or materials that may distort the pattern.
