QR Code Generator
Generate custom QR codes for URLs, Wi-Fi credentials, and contact cards instantly. Export sharp PNG or scalable SVG vector files directly in your web browser.
Tips
- Choose SVG export for physical print projects to ensure crisp lines at any scale without pixelation.
- Set error correction to level M (15%) for general use, or level H (30%) if printed labels may get smudged or scratched.
- Double-check Wi-Fi network names and passwords, as both are strictly case-sensitive in QR payloads.
How to use it
- 1 Select your payload type, such as a website link, plain text, Wi-Fi network credentials, or vCard contact details.
- 2 Enter your information into the input fields to generate the matrix pattern immediately.
- 3 Adjust the error correction level and export size to suit your display or printing requirements.
- 4 Download your code as a raster PNG or vector SVG file, and scan it with a phone camera to verify the payload.
What you should know
Quick Response codes encode alphanumeric data into two-dimensional matrices readable by smartphone cameras and industrial optical scanners. They replace manual typing for URLs, Wi-Fi configurations, plain text notes, and vCard electronic business cards across packaging, storefront displays, tabletop menus, and shipping inserts. Static QR codes embed the raw payload directly into the matrix pattern using Reed-Solomon error correction, eliminating dependence on external redirect servers or hosting subscriptions. Because scanning distance determines the required physical print dimension, vector formats prevent the edge blurriness and pixelation that cause camera focusing failures.
This browser-based generator converts your text, links, network keys, or contact details into standard compliant matrix barcodes without uploading data to external servers. You can adjust the pixel resolution for raster PNG output or export scalable SVG vector files ready for professional desktop publishing software. The tool allows you to tune the error correction level from Low (7%) to High (30%), balancing matrix density against physical damage tolerance. Because all generation happens on your device, private Wi-Fi passwords and personal contact cards remain entirely within your local browser session.
Frequently asked questions
Do static QR codes generated here ever expire?
No, static QR codes never expire because the destination URL, text, or credentials are encoded directly into the pattern itself. As long as your destination link remains active online, the barcode will continue to scan indefinitely.
Which format should I choose for commercial printing?
Use SVG for signs, posters, and product packaging because vector paths scale infinitely without raster artifacts or blurring. If you require a PNG image, export it at a high resolution and print the code at a minimum size of 2 by 2 centimeters.
Is it safe to generate Wi-Fi QR codes with this tool?
Yes, because processing executes strictly inside your browser and no network requests are sent to a remote server. However, anyone who physically scans the printed QR code can read your Wi-Fi password, so place it only in trusted environments.
