About the QR Generator
A QR code is a two-dimensional barcode that any modern smartphone camera can read. Use this generator to turn a URL, a piece of text, Wi-Fi credentials, or a contact card (vCard) into a scannable QR image that you can print, embed, or share online.
QuickToolsLab's QR Generator is free, has no usage limits, and never sends your input to a server. The code is built and rendered entirely inside your browser, which means private data — like Wi-Fi passwords or contact details — never leaves your device.
How it works
Pick the type of payload you want (URL, plain text, Wi-Fi, or vCard), fill in the fields, and choose your preferred error-correction level. Higher correction levels make the code more resilient to physical damage or partial occlusion (helpful for printing on labels) at the cost of slightly more pixels.
Once generated, you can copy the data URL or download the image as PNG (raster, ideal for digital use) or SVG (vector, ideal for print and high-DPI displays).
Privacy
Everything happens client-side using the open-source qrcode library running inside your browser tab. No analytics or server logs capture what you encode.
Frequently asked questions
- Are QR codes generated here free to use commercially?
- Yes. The QR code format is an open ISO/IEC 18004 standard, and the codes produced here have no licensing restrictions. Use them on packaging, business cards, signage, or anywhere else.
- What's the maximum amount of data I can encode?
- QR codes can hold up to 4,296 alphanumeric characters or 2,953 binary bytes at the largest size. In practice, keep payloads short (a URL is best) so the code stays easy to scan on small surfaces.
- When should I use PNG versus SVG?
- PNG is widely compatible and ideal for emails, slide decks, and social media. SVG is a vector format that scales without quality loss — pick it for print materials, large posters, or anywhere it might be resized.
- Does the Wi-Fi QR code share my password securely?
- The Wi-Fi QR format encodes the SSID and password as plain text inside the code. Anyone who scans the printed QR can read them, so treat it like a written-down password and only share it with people you trust.
- Can I add a logo or change colors?
- This tool focuses on standards-compliant, maximally-scannable QR codes, so it doesn't apply branding overlays. Heavy modifications can lower scan reliability, especially on older phones.
