QR Code Generator
Create QR codes for links, vCard contact cards, and WiFi logins, with custom colors and downloadable PNG output. The codes you generate here belong to you with no redirects or analytics middlemen.
Step-by-step guide to the QR Code Generator
- Pick a mode: plain URL or text, vCard contact, or WiFi network.
- Fill in the fields for that mode.
- Customize foreground and background colors if you like.
- Download the PNG and test it with your phone camera before printing.
Practical scenarios for the QR Code Generator
- Linking printed materials, menus, or posters to a website.
- Sharing contact details on business cards via vCard QR codes.
- Letting guests join WiFi by scanning instead of typing passwords.
- Encoding payment or reservation links for events.
How the QR Code Generator works under the hood
The generator encodes your data directly into the QR matrix, choosing an appropriate version and error-correction level, and renders it on canvas for a crisp PNG at your chosen size. vCard mode packs contact fields into the standard contact format phones recognize, and WiFi mode uses the documented scheme that lets Android and iOS devices auto-join. Generation is fully local, so private links and passwords never transit a third-party API.
What the QR Code Generator does not do
Keep contrast high and avoid dense data for print longevity; damaged or low-contrast codes scan poorly. The code's content is permanent once generated, so verify carefully before mass printing.
Common questions about the QR Code Generator
Do these QR codes expire?
No. The destination is encoded in the image itself; plain QR codes never expire or depend on a service.
Is it safe to put my WiFi password in a code?
Anyone who scans it can join your network; treat the code with the same care as sharing the password directly.
Can I change the colors?
Yes, as long as the dark modules stay clearly darker than the light ones for scanning reliability.
