What Is a QR Code Generator?
A QR (Quick Response) code generator creates two-dimensional barcodes that encode information like URLs, plain text, Wi-Fi credentials, contact cards, and more. When someone scans the code with their phone camera, the encoded content opens instantly — no typing required. QR codes were invented in 1994 by Denso Wave for tracking automotive parts, but they've since become a universal bridge between physical and digital experiences. You'll find them on restaurant menus, product packaging, business cards, event tickets, payment systems, and marketing materials worldwide. Our free QR code generator lets you create fully customized codes with your brand colors and logo, then download them as high-resolution PNG or scalable SVG files — ready for print or digital use.
How Does QR Code Generation Work?
QR codes use a matrix of black and white modules (dots) arranged in a square grid on a white background. The data you enter is first encoded using a specific algorithm that converts text into a binary pattern. Error correction codes (Reed-Solomon) are then added so the QR code remains scannable even if up to 30% of the code is damaged or obscured — this is what allows logos to be placed in the center without breaking functionality. Our generator uses the qr-code-styling library which supports multiple encoding modes: numeric (digits only, most efficient), alphanumeric (digits + uppercase letters + some symbols), byte (any character), and Kanji. The encoding mode is automatically selected based on your input to minimize the code's size. When you customize colors, the generator adjusts the module colors while maintaining sufficient contrast for reliable scanning. The final output is rendered either as a raster image (PNG) for web use or a vector graphic (SVG) for print materials at any size.

Benefits
Instant Bridging of Physical and Digital
QR codes turn any physical surface into an interactive touchpoint. Print them on flyers, posters, packaging, or receipts to instantly connect customers to websites, videos, app downloads, or payment pages — no URL typing needed.
Trackable Marketing Performance
By encoding unique URLs with UTM parameters, each QR code becomes a trackable marketing channel. Measure scans by location, time, and campaign to understand which physical placements drive the most digital engagement.
No Expiration or Usage Limits
Unlike dynamic QR codes from some services that stop working after a trial period, QR codes generated here encode data directly into the image. They work forever, with no server dependency, no monthly fees, and unlimited scans.
Brand-Consistent Design
Custom colors and logo placement ensure your QR codes match your brand identity instead of defaulting to generic black-and-white squares. Branded QR codes see higher scan rates because they look intentional and trustworthy.
Frequently Asked Questions
What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that can store URLs, text, contact info, Wi-Fi credentials, and more. When scanned with a phone camera, it instantly opens the encoded content. QR codes can hold up to 4,296 alphanumeric characters and include built-in error correction so they remain scannable even if partially damaged.
Is this QR code generator completely free?
Yes, completely free with no signup, no watermark, and no usage limits. Generate as many QR codes as you need and download them as high-resolution PNG or scalable SVG files. There are no hidden fees or premium tiers for this tool.
Can I customize the QR code colors and add a logo?
Yes. You can change the foreground color (the dots/modules), the background color, and upload your own logo to the center. The QR code's built-in error correction ensures it stays scannable even with a logo overlay. For best results, keep the logo under 30% of the total code area and maintain high contrast between foreground and background.
What's the difference between PNG and SVG download?
PNG is a raster format — best for web, social media, and digital use at the generated resolution. SVG is a vector format — it scales to any size without losing quality, making it ideal for print materials like business cards, posters, banners, and packaging. If you're printing, always choose SVG.
Do the QR codes expire or stop working?
No. QR codes generated here encode data directly into the image (static QR codes). They have no expiration date, no scan limits, and no server dependency. Once created, they work forever as long as the encoded URL or content remains active.
