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 in your browser, so the text or URL you encode is not sent to a 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, so the code is more likely to stay 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.
Frequently Asked Questions
Is the QR code generated on my device?
Yes. The QR code is generated entirely in your browser. No data is uploaded to any server.
What is error correction?
Error correction allows a QR code to remain scannable even if part of it is damaged or covered. Higher levels (Q, H) are more resilient but produce denser codes.
Can I add a logo to my QR code?
Yes. Upload a logo image and it will be centered on the QR code. Use High (H) error correction so the code still has room around the logo.
What file formats can I download?
You can download QR codes as PNG (raster image) or SVG (scalable vector). SVG is recommended for print use.
Is there a limit on how much text I can encode?
QR codes can encode several thousand characters, but shorter content produces cleaner, more easily scannable codes.
Is this tool free?
Yes, completely free with no account required.
