Verified Capabilities
Supports both URL/Text and vCard contact QR codes in one tool.
PNG/JPG for digital sharing, SVG for infinite-scale printing without pixelation.
Choose from 150px web-small up to 1000px print/high-res, applied before the code is generated.
The text or URL you enter is sent to a third-party QR-image API to render the code, like any link-shortener service — avoid encoding passwords or other sensitive data directly. There's also no dedicated Wi-Fi form; you type the WIFI: string yourself.

Tips & tricks
- The image itself is rendered by a third-party QR-code image API, with the text or URL you enter passed along as part of the request — avoid encoding passwords or other sensitive data directly, the same way you would with any URL-shortener or link-preview service.
- For a vCard QR code meant for a physical business card, test-scan it with at least two different phone models first — some older iPhone camera apps import vCard fields slightly differently than Android's default contacts app.
- If the QR code needs to survive a low-quality print job (thermal receipt printers, small stickers), choose SVG output and 300px+ so the individual modules stay large enough to scan reliably after ink spread.
- There's no dedicated Wi-Fi form — to make a Wi-Fi QR code, type the WIFI:T:WPA;S:Name;P:Password;; string yourself into the URL/Text field; the vCard tab is for contact cards only.
Frequently Asked Questions
What is the maximum amount of text a QR code can hold?
A standard QR code can encode up to 4,296 alphanumeric characters. In practice, shorter URLs (under 100 characters) produce simpler, faster-scanning QR codes. Very long URLs or text generate dense codes that some older scanners struggle to read.
What is the difference between PNG and SVG output?
PNG is a raster image — ideal for digital sharing, emails, and screens. SVG is a vector format that scales without pixelation, making it the right choice for print materials like business cards, posters, and packaging.
Can I make a QR code for Wi-Fi credentials?
Yes, but there's no dedicated Wi-Fi form — type the standard Wi-Fi QR string directly into the URL/Text field: WIFI:T:WPA;S:YourNetworkName;P:YourPassword;; (use T:WEP for older routers, or T:nopass with no P: field for open networks). Most phone cameras recognize this format automatically when scanned.
Can I change the color of the QR code?
The generator produces standard black-on-white QR codes optimised for maximum scanner compatibility. Custom colors are possible in design software after export — ensure at least 70% contrast between the dark and light modules to maintain scanability.
Do QR codes expire?
QR codes generated here do not expire — they are static and encode the data directly. However, if the URL you encoded goes offline or changes, the QR code will scan correctly but lead nowhere. Dynamic QR code services let you update the destination URL without reprinting.
How do I test if a QR code works before printing it?
Scan the generated QR code with your phone's camera or a QR reader app before downloading or printing. Test on multiple devices if the code will appear on high-volume print materials. Ensure the destination URL is live and correct.
Is my data safe when using the QR Code Generator?
Yes. Your input is processed on Cloudflare's globally distributed edge network. Data is used only to generate your result and is never stored, logged, or shared with any third party.
What image formats does the QR Code Generator support?
The QR Code Generator works with common image formats supported by your browser, including JPEG, PNG, WebP, and GIF. SVG support varies by tool. No format conversion plugin or driver is needed.
Does the QR Code Generator work offline?
No. Generating the QR code image requires a network request to a QR-image API each time you click Generate — it isn't rendered locally via Canvas like most other image tools on this site. A slow or offline connection will prevent the code from generating.
