Frequently asked questions
Everything you might want to know about QR codes and our generator.
Is this QR code generator free?+
Yes. You can create unlimited static QR codes for free, with full design customization and no signup required.
Do the QR codes expire?+
Static QR codes never expire. The data is encoded directly into the QR pattern, so as long as the destination URL or content remains valid, the QR code will keep working.
What is the difference between static and dynamic QR codes?+
Static QR codes encode the data directly into the pattern — fast, free, and permanent, but the destination cannot be changed once printed. Dynamic QR codes encode a short redirect URL that can be edited later and tracked with scan analytics.
What file formats can I download?+
PNG (multiple resolutions up to 2048×2048), SVG (infinitely scalable vector), and JPG. SVG is recommended for print and large-format use.
Can I add my logo to the QR code?+
Yes. Upload any PNG, JPG, or SVG logo. The QR code's error correction level is automatically set to High so it remains scannable even with a logo overlay.
Will my QR code work on every phone?+
Yes. Every modern smartphone — iPhone (iOS 11+) and Android — can scan QR codes natively from the camera app, no extra app required.
What types of content can I encode?+
Website URLs, plain text, email, SMS, WhatsApp messages, phone numbers, WiFi credentials, vCard contact info, calendar events, geolocation, and links to PDFs, images or videos.
How do I make sure my QR code scans reliably?+
Keep good contrast between foreground and background, leave a quiet zone (margin) around the code, use error correction level Q or H if adding a logo, and test on multiple phones before printing.
What is the smallest size I can print a QR code?+
Roughly 2×2 cm (0.8×0.8 in) for short URLs scanned from 25 cm away. Larger codes scan from further away — a good rule is 1:10 scan-distance to QR-size ratio.
Can I customize the colors and shape?+
Yes — foreground color, background color, gradient fills, dot shape (square, rounded, dots, classy), corner styles, frames with caption text, and logo overlay are all supported.
Do you store the data I encode?+
No. Static QR codes are generated entirely in your browser. Nothing you type is sent to a server.
Can I use the QR codes commercially?+
Yes. QR codes you generate are yours to use freely for personal or commercial purposes.
Why does my QR code look different with a logo?+
Adding a logo covers part of the QR pattern, so we automatically increase the error correction level so the remaining pattern can still be decoded.
What is a vCard QR code?+
A vCard QR code stores complete contact information — name, organization, phone, email, website. Scanning it lets the user save you to their phonebook with one tap.
What is a WiFi QR code?+
A WiFi QR code stores network credentials. Guests scan it and their phone joins the network automatically — no typing the password.
