📖 How to Use
1
Choose QR Type — URL (for websites/links), Text (for any plain text), Email (opens email app), or Phone (opens dialer). The input placeholder will update accordingly.
2
Enter your content in the input field. For URL, include the full address (https://...). For Email, enter the email address. For Phone, enter the number with country code (e.g. +91XXXXXXXXXX).
3
Customise appearance — pick QR foreground color, background color, and adjust the size using the slider.
4
Set Error Correction — use H (Max) if you plan to add a logo (so the QR remains scannable even if the center is covered). Use L (Low) for maximum data density without a logo.
5
Optionally upload a logo — your logo will appear in the center of the QR code. Use a square image with transparent or white background for best results.
6
Click “Generate QR Code” — the QR appears instantly. Click Download PNG to save the image to your device.
❓ Frequently Asked Questions
Is my data sent to any server?▼
No. This tool works entirely in your browser using JavaScript. Your URL, text, or logo is never uploaded or stored on any server. Everything is processed locally on your device.
Why should I use Error Correction Level H when adding a logo?▼
Error correction allows a QR code to be read even when part of it is obscured. Level H (High) can recover up to 30% of damaged/covered data. Since a logo covers the center of the QR, using Level H ensures scanners can still decode it correctly.
What image format should I use for the logo?▼
Use a square PNG image with a transparent or white background. Avoid complex logos with very small details. The logo is displayed at roughly 25% of the QR size — simpler logos appear cleaner and more recognisable.
Can I use a colored background for the QR?▼
Yes! Use the Background Color picker to set any color. However, ensure there is enough contrast between the QR color and background color. Low contrast (e.g. dark QR on dark background) will make the QR unscannable.
What size should I set for printing?▼
For digital use (websites, WhatsApp), 250–300px is sufficient. For printing on paper or banners, use 400–500px for better clarity. Always test scan the QR after downloading before using it on printed materials.
Does the QR code expire?▼
No. QR codes generated here are static QR codes — they never expire. The QR code directly encodes the URL or text you entered. As long as the destination URL remains active, the QR will continue to work forever.
My QR is not scanning. What should I do?▼
Try these fixes: (1) Increase error correction to H. (2) Ensure the QR and background colors have high contrast. (3) If using a logo, try removing it temporarily to verify the base QR works. (4) Make the QR size larger. (5) Avoid very long URLs — shorten them using a URL shortener first.
