Generate customizable QR codes for URLs, text, and data — instantly.
Use QR Code Generator for static QR codes that encode a URL, text, WiFi details, or contact information directly into a PNG or SVG. Scan reliability depends on more than the data: size, contrast, quiet zone, error correction, and the final print or screen context all matter. Static QR codes are not tracking systems, so use a redirect URL you control if you need analytics or an editable destination.
Increase physical size, preserve the quiet zone, and use strong foreground/background contrast.
Use higher error correction, keep the logo small, and test the final design at real size.
Static QR codes cannot be edited. Encode a redirect URL that you control if future changes or analytics are required.
Shorten the URL or payload and avoid encoding long text when a landing page link would work better.
QR code generation happens in the browser for normal use. Do not encode secrets, private WiFi credentials, unreleased URLs, or personal data unless you are comfortable with anyone scanning the final code.
Use the shortest accurate URL or text value and decide whether PNG or SVG suits the destination.
Choose contrast, size, and error correction with enough quiet zone around the code.
Test the final image on real phones, screens, or printed proofs before distributing it.
Generate an SVG code for a landing page and test a printed proof at the intended size.
Create a QR code for guest network details and confirm the encoded data is appropriate to share.
URLs, plain text, WiFi credentials (auto-connect), email addresses, phone numbers, SMS messages, vCard contacts, and geographic coordinates. URLs are the most common use case.
Version 40 (177x177 modules) can store up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes of binary data. Practical URLs should stay under 300 characters for reliable scanning.
Yes, you can change foreground and background colors. Adding a small center logo (up to 10% of QR code area) works thanks to error correction. Use High (H) error correction level when adding logos.
Minimum 2x2 cm (0.8x0.8 inches) for close-range scanning (phone held near the code). For posters or signage, scale proportionally — 10 cm for 1 meter viewing distance, 30 cm for 3 meters.
Static QR codes (which encode data directly) never expire. Dynamic QR codes (which encode a redirect URL) can stop working if the redirect service goes offline or the link is deactivated.
A static QR code contains the exact text or URL encoded at creation time. Once printed, changing the destination requires printing a new QR code unless you used a separate redirect URL you control.
Higher error correction makes the QR code more tolerant of small damage, logos, or low-quality printing, but it also creates a denser pattern. Test the final printed size with real phones before distributing it.
Low contrast, tiny print size, glossy material, crowded quiet zones, and overly long URLs can all reduce scan reliability. Shorten the destination, keep margins clear, and test from the expected viewing distance.
No. The generated QR image is static and does not add analytics by itself. If you need scan reporting, use your own redirect URL or campaign link and make that tracking clear to users.
