Free Online QR Code Generator
Create custom QR codes for links, text, email, phone, and Wi-Fi—then download a high-resolution PNG.
Use a square logo. Keep it small so scanners can still read the code.
Test the finished QR code with your phone before printing or publishing it. High error correction and a small center logo give the best balance between branding and scannability.
About the QR Code Generator
A QR code stores information in a square pattern that a phone camera can read instantly. This generator creates QR codes for links, plain text, email addresses, phone numbers, SMS messages, and Wi-Fi networks. You can change the colors, add a logo, and download a high-resolution PNG.
What can you encode?
- Website URLs: open a page, product, menu, or booking form.
- Wi-Fi networks: let guests join without typing a password.
- Email, phone, and SMS: start a message or call with one scan.
- Plain text: share a code, note, coupon, or instruction.
Tips for scannable QR codes
- Keep strong contrast between the foreground and background. Dark code on a light background works best.
- Leave the quiet zone around the code. A margin of at least 4 modules is recommended.
- Keep a center logo below 30% of the width and use high error correction.
- Do not place a QR code on a curved, reflective, or very small surface.
How to create a QR code
- Choose the content type and enter your URL, text, or Wi-Fi details.
- Pick a size, error correction level, and colors.
- Optionally upload a logo and adjust its size.
- Download the PNG and test it with your phone.
Frequently asked questions
Do QR codes expire?
No. A QR code is just an image containing data. It stops working only if the destination URL stops working or the code is printed too poorly to scan.
Can I add a logo?
Yes. A small center logo is safe with high error correction. Very large logos can make the code unreadable.
Is there a scan limit?
No. The QR code is generated locally in your browser, and there is no tracking or scan limit.
