Free QR Code Generator
NToolHub’s QR Code Generator turns any text, link, or contact detail into a scannable QR code in seconds. It is built for marketers, small business owners, teachers, and event organizers who need professional codes without installing software or creating an account. Pick your size, brand colors, and error-correction level, then download a crisp PNG ready for print or screen.
How to Use the QR Code Generator
- Type or paste the text, URL, or contact information you want to encode.
- Customize the size, foreground and background colors, and error-correction level.
- Click “Generate QR Code” to render your code instantly in the preview area.
- Download the PNG and use it on flyers, packaging, menus, or websites.
Features
The generator supports five output sizes from 128 to 512 pixels, four error-correction levels (L, M, Q, H) for damaged or stylized codes, and full color control so codes can match your branding. Codes are rendered locally with a proven QR engine and exported as high-quality PNG files.
Benefits & Use Cases
QR codes bridge print and digital: restaurants put them on menus, retailers on packaging, and presenters on slides so audiences can open a link without typing. Because everything runs in your browser, sensitive URLs or internal links are never sent to a server, and there are no watermarks, scan limits, or accounts to manage.
Tips
Use high contrast between the foreground and background for reliable scanning, and test the code with your phone camera before printing. Choose a higher error-correction level if the code will be printed small, placed outdoors, or partially covered by a logo. For print work, generate at 512 pixels to keep edges sharp.
Frequently Asked Questions
Are the QR codes generated here free to use?
Yes. Every QR code you create is completely free, with no watermarks, scan limits, or expiry dates. You can use them for personal or commercial projects.
Do my QR codes expire?
No. The codes encode your text or link directly, so they work as long as the encoded content itself remains valid. There is no subscription or time limit.
Is my data uploaded anywhere?
No. The entire generator runs in your browser using JavaScript. Your text and links never leave your device.
What error correction level should I choose?
Medium works for most cases. Choose High if the code will be printed small, displayed outdoors, or partially obscured, since it stays readable even when up to 30 percent of the code is damaged.
