QR Code Generator
URLs, Wi-Fi, phone numbers, email — turn it into a QR code, with your own colors and logo.
Pick a type, enter your content, and customize the colors and logo to match your brand before downloading.
How does a QR code work?
A QR (Quick Response) code is a two-dimensional barcode that encodes text data as a pattern of black and white squares. A phone camera can decode it instantly into a URL, Wi-Fi credentials, contact info, and more. Compared to a traditional 1D barcode, QR codes hold much more data and include built-in error correction, so they still scan correctly even if part of the code is dirty or damaged.
What can you put in a QR code?
Common use cases include: plain text, a URL (opens a webpage directly), Wi-Fi credentials (connects automatically without typing a password), a phone number (opens the dialer), an email address (opens a pre-filled email draft), or an SMS. This tool supports all of these — just pick the type and fill in the content.
Frequently asked questions
Will a QR code still scan if I add a logo in the middle?
Yes, as long as the logo isn't too large — typically under 20-30% of the total area. QR codes have built-in error correction, so even with a chunk of the pattern covered by a logo, a scanner can still reconstruct the full data from the surrounding squares. That's why many brands place their logo right in the center.
Can I use any colors I want for a QR code?
You can customize colors, but contrast matters. If the foreground and background colors are too similar (like light gray on white), the camera struggles to distinguish the squares, which slows down or breaks scanning. Stick to a dark foreground on a light background for reliable results.
Do QR codes expire?
The QR code image itself never expires — it will keep scanning correctly forever, since it's a static image. But if it encodes a URL and that webpage is later taken down or changed, scanning will lead to a broken link. That's an issue with the destination page, not the QR code itself.

Keep enough quiet space around the code, avoid tiny print sizes, and test on more than one phone. Prefer HTTPS links for web targets. Regenerate if the destination URL changes.
