What is a QR code?
A QR code is a two-dimensional barcode that encodes a URL or text as a black-and-white pattern. Scanning it with a smartphone camera opens the link instantly, which is why they're used everywhere print meets online — business cards, flyers, restaurant menus, Wi-Fi sharing, and more.
How to use it
① Enter a URL
Type the URL you want to encode and a QR code is generated instantly.
② Add a logo if you'd like
Upload a logo image and it's placed in the center of the QR code. Error correction is set to the highest level (H), so it stays scannable even with a logo overlaid.
③ Download or copy as PNG
Download the result as a PNG file, or copy it straight to your clipboard to paste into a document.

Frequently asked questions
Does adding a logo break scanning?
No — error correction is set to the highest level (H), designed to stay readable with a logo in the center. There's still an upper limit on logo size, since an oversized logo can make scanning unreliable.
Does the QR code expire?
No. The URL you entered is embedded directly in the code, so it stays scannable for as long as the destination page exists.
Is my image uploaded to a server?
No. Generating the QR code and overlaying a logo both happen entirely in your browser.
Is it free?
Yes, completely free with no sign-up, unlimited use.
