About QR Code Generator
QR codes are two-dimensional barcodes that can encode URLs, text, Wi-Fi credentials, contact information, and more. They are ubiquitous in marketing materials, product packaging, restaurant menus, event tickets, and business cards. This tool generates QR codes from any text input with customizable foreground and background colors, letting you match your brand palette or design requirements. Download your QR code as a PNG for print materials and presentations, or as an SVG for scalable, resolution-independent output that looks crisp at any size. Common use cases include creating QR codes for website URLs, app download links, Wi-Fi network credentials for guests, event registration pages, and vCard contact information. The generation uses the qrcode library and runs entirely in your browser — no data is sent to any server, which is important when encoding sensitive URLs containing authentication tokens or private network credentials. The generated QR codes follow standard specifications and are scannable by all modern smartphone cameras and QR reader apps.
Questions
Is my data sent to a server?
No. QR codes are generated entirely in your browser using the qrcode library.
What's the maximum text length for a QR code?
QR codes can encode up to about 4,296 alphanumeric characters or 2,953 bytes. In practice, keeping content under 500 characters ensures reliable scanning.
Can I customize the foreground and background colors?
Yes — both colors are configurable. Just keep enough contrast between them: scanners need a clear difference in luminance to detect the modules. Avoid light-on-light or busy backgrounds.
Should I download the PNG or the SVG?
The PNG is a 300×300 pixel bitmap — fine for screens, chat, and slides. For print or anything large, download the SVG: it is vector, so it stays sharp at any size and resolution.
Will the code still scan if part of it is covered or damaged?
Usually — codes are generated at medium error correction, which can reconstruct roughly 15% of damaged or obscured modules. A small sticker over the middle often survives; covering one of the three corner finder squares usually breaks scanning.
Is my file uploaded to a server?
No. Transmute processes everything locally in your browser using JavaScript and WebAssembly. Your files never leave your device — there is no server, no upload, no cloud processing.
