Create QR Codes for Websites & Business Cards

How to Create a QR Code for Your Website

Generating a QR code for a website takes less than 10 seconds with our tool. Simply paste your full URL (including https://) into the URL tab, choose your preferred size and colors, and click Generate. Your QR code for the website is ready to download immediately — no account needed.

Website QR codes are ideal for print ads, posters, packaging, storefront windows, and anywhere you want to drive visitors to a specific page. Use them to link to your homepage, a product page, a promo landing page, or even a booking form. A well-placed QR code for a website can significantly increase scan-to-visit conversion for physical marketing materials.

💡 Pro tip: When you create a QR code for a website, use a short or redirected URL (e.g. via our free URL shortener) to keep the QR code less dense and easier to scan, especially at small print sizes.

How to Create a QR Code for a Business Card

A QR code on a business card is one of the most practical uses of the technology. Instead of cluttering your card with every detail, you can print a single compact QR code that, when scanned, instantly saves your full contact information — name, phone, email, company, and website — directly to the person’s phone contacts.

To create a QR code for a business card, switch to the vCard tab in our generator, fill in your contact details, customize the look to match your brand, and download the SVG version for crisp, print-ready output. Most business card printers accept SVG or high-res PNG files. A minimum size of 2×2cm is recommended for business card QR codes so they scan reliably.

This is especially useful for networking events, conferences, trade shows, or any situation where exchanging contact details quickly matters. A QR code for a business card is the modern, frictionless alternative to typing numbers manually.

How to Use the QR Code Generator

Step 1 – Choose Your QR Code Type

Select from four types: URL to link to any website, WiFi to share network access, vCard to create a digital business card QR code, or Text for any custom message. Each tab shows only the relevant input fields for a clean, simple experience.

Step 2 – Enter Your Data

For website QR codes, paste your full URL. For business card QR codes, fill in your contact details across the vCard fields. For WiFi, enter your network name, password, and security type. All inputs update the preview in real time as you type.

Step 3 – Customize Your QR Code

Stand out with a custom QR code that matches your brand. Adjust the size slider, pick dark and light colors using the color pickers, and choose an error correction level. Higher error correction (Q or H) makes QR codes more resilient if part of the code is covered or damaged — great for printing on textured surfaces.

Step 4 – Download & Use

Click PNG for digital use, JPG for web embeds, or SVG for professional printing. All formats are free with no watermarks. Use our percentage calculator to track scan rates and conversion for your campaigns.

Frequently Asked Questions

What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that stores information — like a website URL, contact details, WiFi credentials, or text — and can be read instantly by a smartphone camera. Unlike traditional barcodes, QR codes can store much more data and can be scanned from any angle.
Is this QR code generator really free?
Yes, 100% free with zero limitations. You can create unlimited custom QR codes without signing up, paying, or downloading anything. All features — including custom colors, all QR types, and all download formats — are included at no cost.
How do I create a QR code for my website?
Click the URL tab, paste your full website address (e.g., https://yoursite.com), customize the size and colors if you like, then click Generate and download. Your QR code for the website is ready in seconds.
How do I create a QR code for a business card?
Switch to the vCard tab and enter your contact details — name, email, phone, company, and website. Generate the QR code and download it as SVG for best print quality. Print it on your business card at a minimum size of 2×2cm for reliable scanning.
Is this a good free alternative to a Google QR code generator?
Yes. Google doesn’t offer a dedicated standalone QR code generator, but users often search for one. Our free QR code generator works entirely in the browser, requires no Google account, and supports more customization options than most built-in tools — including custom colors, multiple QR types, and SVG download.
Do QR codes expire?
Static QR codes (like those this tool generates) never expire. The data is permanently embedded in the code itself. However, if your QR code links to a URL, make sure that page stays live — a broken link makes the QR code useless even though the code itself is still valid.
What size should a QR code be on a business card?
For business cards, use a minimum of 2×2cm (roughly 240×240px at 300 DPI). Smaller than this risks scan failures, especially indoors or with lower-quality cameras. Download the SVG format for perfectly sharp, scalable output regardless of print size.
What’s the difference between PNG, JPG, and SVG for QR codes?
PNG is best for digital use — lossless quality, transparent-background support. JPG is smaller in file size, suitable for web. SVG is a vector format that scales infinitely without losing quality, making it ideal for professional printing on business cards, posters, and signage.
Can I use custom colors in my QR code?
Yes — you have full control over both the dark and light colors. Just make sure there’s enough contrast between the two colors for reliable scanning. Very light dark colors or very dark background colors can cause scan failures. Always test your custom QR code on a real device before printing.
How do WiFi QR codes work?
A WiFi QR code encodes your network name (SSID), password, and security type into a scannable format. When someone scans it with an Android or iOS device, the phone automatically prompts them to join the network — no typing required. Works natively on most modern smartphones without any app.
Can I edit a QR code after creating it?
Static QR codes cannot be modified after generation — the data is baked into the pattern. If you need to change the destination, simply generate a new QR code and replace the old one. For mutable QR codes that can be redirected without reprinting, you’d need a dynamic QR code service.

QR Code Best Practices

Always Test Before Printing

Before committing to a print run, scan your QR code using multiple devices — at least one Android and one iOS — in various lighting conditions. A QR code that looks correct on screen can still fail to scan if the contrast is too low or the size is too small.

Maintain Strong Color Contrast

The dark color should be significantly darker than the light background. Avoid pastel-on-pastel or low-contrast combinations. When using a custom QR code with branded colors, use our color code converter to verify hex values and contrast ratios before finalizing.

Include a Clear Call to Action

Don’t just place a QR code and hope people scan it. Always add a short instruction nearby: “Scan to visit our website,” “Scan to save my contact,” or “Scan to connect to WiFi.” This increases scan rates significantly, especially for first-time QR code users.

Use the Right Format for the Job

For business cards, brochures, and signage, always use SVG — it prints at any resolution without pixelation. For digital assets like email banners or social media, PNG is the right choice. Use JPG only when file size is a constraint and some quality loss is acceptable.

Leave Adequate Quiet Zone

The “quiet zone” is the white space border around the QR code. Never crop it or let other design elements overlap with it — scanners use this blank space to identify where the code starts and ends. A quiet zone of at least 4 modules (cells) wide is recommended by the QR standard.
