What This Tool Does

It generates a QR code from any text or URL you enter. Set the size and colors, click generate, and download the QR code as a PNG. The result is a scannable, high-quality QR code ready to use anywhere.

QR codes are a practical bridge between physical and digital. On a business card, a QR code links directly to a website or contact page. On product packaging, it links to instructions or a registration page. On a restaurant menu, it opens the full menu online. The QR code removes the step of typing a URL.

How to Use It

• Enter the URL or text you want to encode in the input field.
• Adjust the size slider to set the output dimensions.
• Set the foreground color (the dark squares) and background color.
• Click Generate QR Code.
• Download the PNG image.

What You Can Encode

Any text can go into a QR code. URLs are the most common use, but you can also encode plain text messages, email addresses, phone numbers, WiFi credentials, or SMS messages.

For URLs, include the full address with https:// at the start. Short URLs produce simpler, easier-to-scan QR codes since less data means fewer squares in the code. If your URL is very long, use the URL Shortener tool first to create a shorter version, then generate the QR code from that.

For contact information, the vCard format encodes a full contact record that most phone cameras can parse directly into the contacts app. Type the vCard text manually if you need this format.

Common Uses

• Creating QR codes for business cards to link to a website or LinkedIn profile
• Adding QR codes to printed flyers or posters for event registration
• Putting QR codes on product packaging to link to instructions or support pages
• Creating QR codes for restaurant menus or ordering systems
• Adding QR codes to presentation slides to link to referenced resources

Size and Print Recommendations

For digital display on screens, 200px is enough for most uses. For print, use at least 300px. When printing at physical sizes, the QR code should be at least 2 cm by 2 cm to scan reliably. Smaller than that, most phone cameras struggle.

High error correction is enabled, which means the QR code can still scan correctly even if up to 30 percent of it is obscured or damaged. This is useful if you plan to add a logo on top of the QR code.

Test the QR code before distributing it. Scan it with your phone to confirm it goes to the right destination and that the URL is correct.

Frequently Asked Questions

Can I use the QR code commercially?

Yes. Generated QR codes have no restrictions on use.

What can I encode in a QR code?

URLs, plain text, email addresses, phone numbers, WiFi credentials, or any short text string.

How large should the QR code be for print?

At least 300px for the image, and at least 2cm by 2cm in the final print.

Will the QR code expire?

No. The code itself does not expire. If you encoded a URL and that URL changes, the QR code will still scan but the destination will be wrong.

Can I change the colors?

Yes. Set any foreground and background color using the color pickers.

Can I put a logo in the middle of the QR code?

The QR code downloads as a PNG. You can open it in a design tool and add a logo on top. High error correction ensures it still scans with up to 30 percent obscured.
