QR codes are a fast and convenient way to share information. Our generator creates codes instantly in your browser - no data is sent to servers, keeping your information private. Download in high-resolution PNG or vector SVG format for print or digital use. ## QR Code Tips - Maintain high contrast between the foreground and background colors. Dark code on a light background scans most reliably across all devices. - Keep the minimum printed size above 2 cm by 2 cm. Smaller codes may not scan consistently, especially from a distance or on curved surfaces. - Use an error correction level of at least M (medium) for printed materials. Higher correction allows the code to remain readable even if part of it is damaged or obscured. - Always include a quiet zone of at least 4 modules around your QR code. This whitespace border helps scanners distinguish the code from surrounding graphics. - Test your QR code on multiple devices and scanning apps before distributing it. Lighting, screen glare, and camera quality can all affect scan reliability. ## Frequently Asked Questions ### Are QR codes generated securely? Yes, all QR codes are generated entirely in your browser using JavaScript. No data is sent to our servers, so your information remains completely private. ### What's the best size for a QR code? For digital use, 300-500px is usually sufficient. For print materials, use 1000px or higher to ensure the code scans properly even when printed large. ### Can I customize the colors of my QR code? Yes! You can change both the foreground (the code itself) and background colors. Just make sure there's enough contrast for scanners to read it properly. ### What's the margin/quiet zone for? The quiet zone is the white space around the QR code. It helps scanners identify where the code begins and ends. We recommend at least 2-4 blocks of margin. ### Which format should I download - PNG or SVG? Use PNG for digital purposes like websites and social media. Use SVG for print materials as it can be scaled to any size without losing quality. ### Does the QR Code Generator require a signup or add a watermark? No. It is available with no watermark, no branding, and no signup required. You get full-resolution downloads in both PNG and SVG formats without any restrictions. ### How much data can a QR code hold? A QR code can store up to 7,089 numeric characters or 4,296 alphanumeric characters. For practical use, shorter content like URLs and contact info produces smaller, more scannable codes. ### What is error correction in QR codes? Error correction allows a QR code to remain readable even if part of it is damaged. There are four levels: L (7% recovery), M (15%), Q (25%), and H (30%). Higher levels make the code denser but more resilient. ### Can I use these QR codes commercially? Yes. QR codes generated here are yours to use for any purpose, including commercial use on packaging, business cards, marketing materials, and signage. There are no licensing restrictions. ### Do QR codes expire? Static QR codes like the ones generated here never expire. The data is encoded directly in the image. However, if the QR code points to a URL, the code will stop working if that URL goes offline. ## Related Tools - [Barcode Generator](https://findutils.com/generate/barcode-generator/) - [UUID Generator](https://findutils.com/generate/uuid-generator/) - [Signature Generator](https://findutils.com/generate/signature-generator/) - [Favicon Generator](https://findutils.com/design/favicon-generator/) - [Meta Tag Generator](https://findutils.com/seo/meta-tag-generator/) - [Email Signature Generator](https://findutils.com/generate/email-signature-generator/) - [Image Converter](https://findutils.com/convert/image-converter/) - [Base64 Encoder](https://findutils.com/developers/base64-encoder/)
