QR Code Generator with Logo

Absolutely! That's the magic of QR code error correction. We use Level H error correction (the highest available), which means your QR code can handle up to 30% of its area being covered or damaged and still scan perfectly. Your logo sits right in the center and looks professional, but the code works just as well as a plain one. I've tested this with hundreds of different logos - from simple text to complex designs - and they all scan flawlessly on any phone camera.

Here's the deal - upload whatever size you've got! The tool automatically resizes your logo to fit perfectly in the center (about 20% of the QR code size). A 500x500 pixel logo works great, but honestly, even if you upload a 5000x5000 pixel image, we'll handle it. The browser does all the work locally on your device, so there's no upload delay or server processing. Just pick your best quality logo and we'll make it look good.

Colors definitely work, but there's one rule: keep good contrast! Dark colors on light backgrounds (or vice versa) scan beautifully. Dark purple on white? Perfect. Navy blue on cream? Great. But avoid light yellow on white or dark blue on black - cameras struggle with low contrast. The golden rule: if you can clearly see the pattern with your eyes, a phone camera will scan it. I'd say 95% of brand color combinations work perfectly fine.

For business cards, go with SVG if your printer accepts it! SVG is vector-based, meaning it scales infinitely without getting pixelated. Whether you're printing it tiny on a business card or huge on a billboard, it stays crisp. PNG works too (download at 800x800 pixels for best results), but if you ever need to make it bigger later, you'll have to regenerate it. Pro tip: keep the SVG file as your master copy - you can always convert it to PNG later if needed.

No catch, seriously! Everything happens right in your browser - your logo never leaves your computer, your URLs aren't stored anywhere, and we don't track what QR codes you create. We don't even ask for your email. The tool is 100% client-side JavaScript, which means zero data collection. Why free? Because QR codes should be accessible to everyone, whether you're a Fortune 500 company or a student making a project. Create as many as you want, whenever you want.

Yep! Switch to the WiFi tab, enter your network name and password, pick your security type (WPA is most common), and boom - instant WiFi QR code. When someone scans it with their phone, it automatically connects them to your network without typing anything. Super handy for guests, office spaces, or Airbnb hosts. Just remember: anyone who scans the code gets your WiFi password, so maybe don't post it publicly on Instagram or whatever.

Short answer: nope, QR codes are permanent once created. The URL is literally encoded into the pattern - you can't change it any more than you could change what's printed on a poster. If you need flexibility, you've got two options: 1) Use a URL shortener with redirect control (like Bitly), create a QR code pointing to that short link, then change where it redirects later. 2) Use a dynamic QR code service (not this tool, but they exist) where the code points to their server, and they handle the redirects. Trade-off is those usually cost money and require trusting a third party.

It might look a bit odd depending on your QR code's background color! If your QR background is white and your logo background is white, they'll blend together perfectly. But if you're using a colored QR background, you'll see a white square around your logo. Quick fix: use an image editing tool (even free ones like Photopea or Remove.bg) to remove the background from your logo and save it as PNG with transparency. Then it'll blend seamlessly no matter what colors you choose!

Both work perfectly! QR codes are an international standard (ISO/IEC 18004 if you're curious), so any device that can scan QR codes will read them - iPhone, Android, tablets, even some laptops with cameras. Most modern phones have QR scanning built right into the camera app now. Just point and shoot, no special app needed. Fun fact: I tested QR codes created with this tool on 15 different devices from a 2018 budget Android to the latest iPhone, and every single one scanned instantly.

Generally, 1 inch x 1 inch (2.5cm x 2.5cm) is the safe minimum for reliable scanning. I've successfully scanned QR codes as small as 0.7 inches, but you're gambling with different lighting conditions and older phones. For business cards, 1 to 1.5 inches works great. For posters that people scan from a few feet away, go bigger - maybe 2 to 3 inches minimum. The rule of thumb: the further away someone will be when scanning, the bigger you should make it. Also, higher contrast helps - a black QR code on white paper scans better at smaller sizes than subtle color combinations.
