About QR Code Generator

Error correction is the setting worth understanding: higher levels rebuild a code that is partly obscured or scuffed, at the cost of a denser pattern. Raise it for anything printed on a label that will take wear, keep it low for clean on-screen display.

Generate scannable QR codes for links, WiFi networks, contact cards (vCard), SMS messages and email, then fine-tune the size, foreground and background colours and error-correction level before exporting a crisp PNG or vector SVG. A WiFi QR lets guests join your network with one scan; a vCard QR drops your contact details straight into a phone; a URL QR bridges print and web.

Higher error-correction levels add redundancy so a code still scans when part of it is dirty, printed small or covered by a logo. The image also encodes your value directly rather than pointing at a shortener, so it keeps working indefinitely — there is no redirect to expire, break or start charging.

Frequently asked questions

Do QR codes expire or track scans?

No. These are static QR codes that encode your data directly, so they never expire and contain no tracking redirect. Unlike shortened URLs or QR services that use redirect servers, your data is baked into the code itself, making it permanently scannable regardless of how much time passes. This also means no company can track who scans your code or revoke access after publishing. What you encode is exactly what a scanner reads — a WiFi password, website URL, or contact card stays valid forever.

Is my WiFi password or contact data uploaded?

No. Everything runs locally in your browser using standard web APIs — your text, files and inputs are never uploaded to a server, so the tool works even offline once the page has loaded.

Should I download PNG or SVG?

Use PNG for quick sharing and on-screen use, and SVG for print or large signage — being vector, an SVG stays razor-sharp at any size. PNG is raster-based and ideal for quick sharing via email, messaging apps, or embedding in websites without any quality concerns at typical screen resolutions. SVG files are resolution-independent, so they scale perfectly from business cards to billboards without any pixelation or quality loss. Choose PNG for convenience and on-screen display, and SVG for professional printing, signage, or any scenario where the QR code will be enlarged significantly.
