QR Code Generator — Free Custom QR Code Creator
QR codes have become the bridge between the physical and digital worlds. A customer scans a code on a restaurant table to see the menu. A shopper scans a product label to read reviews. A patient scans a hospital wristband to access their records. Creating a QR code should be as simple as scanning one. Our free QR Code Generator lets you design fully customized, scannable QR codes for any purpose — URLs, text, WiFi credentials, contact cards, and more. You control the colors, shapes, and size while the tool ensures every code remains readable by any smartphone camera.
What Is a QR Code and How Does It Work?
A QR code (Quick Response code) is a two-dimensional barcode invented in 1994 by Denso Wave, a Japanese automotive company. Unlike traditional one-dimensional barcodes that store data in a series of vertical lines, QR codes store information in a grid of black and white modules arranged in a square pattern. This grid structure allows them to store significantly more data — up to several thousand characters — and to be read from any angle.
QR codes consist of three main parts. The data modules are the small squares that encode your information. The position markers are the large squares in three corners that help scanners orient the code. The quiet zone is the empty margin around the code that separates it from surrounding content. All three parts must remain intact for reliable scanning.
The magic of QR codes lies in their error correction capability. Even if part of the code is damaged, obscured, or covered by a logo, the built-in redundancy allows scanners to reconstruct the missing data. This is why you can place a small brand logo in the center of a QR code and still have it work — the error correction fills in the gaps.
Modern smartphones read QR codes natively through the camera app. No special software is required. When a user points their camera at a QR code, the phone detects the position markers, decodes the data modules, and presents the content — usually a URL to open, text to display, or a WiFi network to join.
How to Use the QR Code Generator
Creating a custom QR code takes under a minute. Enter your data, adjust the design, and download the result.
- Enter your content in the data input field. This can be a website URL, plain text, a phone number, a WiFi connection string, an email address, or any text-based information.
- Set the width using the size slider. Choose from 128 pixels for small digital uses up to 1024 pixels for large print materials.
- Adjust the margin to control the quiet zone around the code. A larger margin improves scannability when the code is placed near other visual elements.
- Customize the style. Choose a dot style for the data modules, select colors for the dots and background, and style the corner squares and corner dots independently.
- Select an error correction level. Higher levels create more redundant data, allowing the code to remain scannable even if partially damaged or covered.
- Preview your code in real time. The live preview updates instantly as you adjust settings, so you can see exactly how your code will look.
- Download or copy. Save your QR code as a PNG image for digital use or an SVG vector file for print. You can also copy it directly to your clipboard.
The generator creates a new code automatically as you type, so you see your QR code form in real time without clicking any buttons.

Dot Styles
The dot style changes the appearance of every individual data module in the QR code. Square produces the classic sharp-edged look. Dots create circular modules for a softer, more modern aesthetic. Rounded offers slightly rounded squares that blend accessibility with personality. Classy and Classy Rounded produce diamond-like shapes that work well for premium brands. Extra Rounded creates heavily rounded squares that feel friendly and approachable.
Corner Styles
The three position markers in the corners are what scanners look for first. By styling the corner squares and corner dots separately from the data modules, you can create visual hierarchy and brand recognition while maintaining scannability. The corner squares form the outer frame; the corner dots sit inside them. Using contrasting colors for these elements can create striking designs that still function perfectly.
Error Correction Levels
| Level | Recovery Capacity | Best Used For |
|---|---|---|
| L (Low) | ~7% | Clean digital displays, screens, and presentations where the code will not be damaged |
| M (Medium) | ~15% | General purpose use, the default balance between data density and redundancy |
| Q (Quartile) | ~25% | Print materials, posters, and flyers where the code might be slightly wrinkled or worn |
| H (High) | ~30% | Harsh environments, codes with logos overlaid, or situations where damage is likely |
Higher error correction levels add more redundant data modules, which makes the code more complex and slightly larger visually. For most purposes, Medium is the optimal balance. Use High only when you need to overlay a logo or when the code will be exposed to rough handling.

The position markers, quiet zone, and error correction are all handled automatically — you just focus on the design.
Real-World Use Cases
Restaurants and Cafes Print QR codes on table tents or stickers so customers can view digital menus, place orders, or pay without touching physical menus. A customized code in the restaurant's brand colors feels intentional rather than generic. Use Medium error correction for indoor settings where codes stay clean.
Retail and E-Commerce Place QR codes on product packaging, shelf tags, or window displays. Shoppers scan to see reviews, compare prices, watch demonstration videos, or access exclusive discounts. A branded QR code with rounded dots and matching colors reinforces brand identity at the point of purchase.
Events and Conferences Print QR codes on tickets, badges, and signage. Attendees scan to access schedules, speaker bios, networking platforms, or live polls. For large venues, use a higher size setting and ensure adequate contrast so codes scan reliably from a distance under varying lighting.
Real Estate and Property Management Add QR codes to For Sale signs, brochures, and listing sheets. Prospective buyers scan to see virtual tours, floor plans, pricing history, or contact the agent directly. A customized code with the agency's brand colors makes every listing look professional and cohesive.
Healthcare and Medical Offices Use QR codes on appointment cards, prescription labels, and patient wristbands. Patients scan to check in, access educational materials, view lab results, or confirm medication schedules. High error correction is recommended for wristbands that may be exposed to moisture and handling.
Marketing Campaigns Include QR codes in print advertisements, direct mail, billboards, and transit posters. Track engagement by using unique URLs for each placement. A visually distinctive code with custom styling draws more scans than a plain black-and-white square because it signals that the code belongs to your brand.
WiFi Sharing
Generate a QR code containing your WiFi network name and password. Guests scan to connect instantly without typing long passwords. This is perfect for offices, Airbnbs, coffee shops, and home networks. Use the Text input format and structure the data as WIFI:S:network_name;T:WPA;P:password;;.
Education and Training Teachers place QR codes in textbooks, handouts, and classroom displays. Students scan to access supplementary videos, interactive quizzes, or assignment submission portals. Custom colors matching the school or course branding make the materials feel integrated and professional.
Tips and Best Practices
- Maintain strong contrast. The most important rule of QR code design is that the data modules must be significantly darker than the background. Light blue dots on a white background might look elegant but will fail to scan. Dark dots on a light background are the most reliable combination.
- Test before publishing. Always scan your QR code with multiple devices and apps before distributing it. Test under the actual conditions where it will be used — on a screen, on paper, in sunlight, and in low light.
- Leave adequate quiet zone. The margin around your QR code should be at least four modules wide. Our margin slider helps you set this correctly. Never place text, images, or patterns inside the quiet zone.
- Avoid light colors for dots. Even with high error correction, light-colored dots on light backgrounds reduce scannability. If your brand requires light colors, use a dark background with light dots instead of the reverse.
- Size matters. For print, use at least 2 centimeters by 2 centimeters. For digital, ensure at least 200 pixels width. Codes that are too small may not scan reliably, especially from a distance or with older cameras.
- Use the lowest error correction that meets your needs. Higher levels create denser, more complex codes that can be harder to scan. Only use High if you plan to overlay a logo or if the code will be exposed to damage.
- Keep URLs short. Long URLs create more complex QR codes with smaller modules that are harder to scan. Use a URL shortener for long links to create cleaner, more reliable codes.
- Download SVG for print. PNG images pixelate when enlarged. SVG files scale infinitely without losing quality, making them ideal for large-format printing like banners and billboards.
Frequently Asked Questions
Is the QR Code Generator free to use?
Yes. The QR Code Generator is completely free with no usage limits, no registration, and no watermarks. You can generate and download as many QR codes as you need.
Will a customized QR code still scan?
Yes, as long as you maintain adequate contrast between the dots and the background. The position markers must remain recognizable, and the quiet zone must be preserved. Our generator handles the technical requirements automatically, so customizing colors and shapes will not break scannability.
What is error correction and why does it matter?
Error correction adds redundant data to the QR code so that even if part of the code is damaged, obscured, or covered by a logo, the scanner can still reconstruct the full message. Higher levels add more redundancy but create denser codes. Choose Low for clean environments and High for codes that need to survive damage or display a brand logo.
Can I put my logo in the center of a QR code?
Yes, but you need High error correction to do this safely. The logo will cover some data modules, and the error correction fills in the missing information. Keep the logo small — no larger than 15 percent of the code area — and centered. Always test the final code extensively before publishing.
What is the difference between PNG and SVG?
PNG is a raster image format that works well for digital use, email signatures, and small print. SVG is a vector format that scales to any size without losing quality, making it ideal for large-format printing like posters, banners, and billboards. For professional print work, always use SVG.
Can I create a QR code for a WiFi network?
Yes. Enter your WiFi credentials in the standard format: WIFI:S:YourNetwork;T:WPA;P:YourPassword;;. Anyone who scans the code can connect to the network instantly without typing the password.
Does this tool work on mobile devices?
Yes. The QR Code Generator is fully responsive and works on smartphones and tablets. The preview, sliders, color pickers, and download buttons are all optimized for touchscreens.
Can QR codes expire?
Static QR codes — the kind generated by this tool — do not expire. They encode the actual data directly into the code pattern. As long as the data remains valid (for example, the URL still works), the QR code will function forever. Dynamic QR codes, which redirect through a third-party service, can expire if the service shuts down or the subscription lapses.
