About this QR code and barcode generator
This page is Codzee's free QR code and barcode generator. Everything runs in your browser: you type the data you want to encode, adjust appearance, then download a PNG for quick sharing or an SVG for sharp print work. You can switch between QR codes (for links, text, WiFi, email, and phone) and common barcode formats for product or inventory identifiers—useful if you need both kinds of codes in one session.
QR codes store information in a two-dimensional grid. That allows longer payloads than old linear barcodes—often a full website URL, but also structured strings such as WiFi credentials. When you pick an input type here, we format the payload the way phones and scanners expect (for example, adding https:// to many URLs, or building a compliant WiFi string). You stay in control of the content: we do not need your email address, and generation does not rely on uploading your data to a server for the core QR and barcode output.
Customization is intentionally straightforward. Size and color impact readability—higher contrast generally scans more reliably, and a larger code is easier to capture from a distance. Error correction lets the code tolerate damage or a centered logo; higher levels add redundancy at the cost of density. For branded QR codes, keep logos small relative to the full pattern, preview on a real device, and leave a quiet zone around the code so cameras can lock onto the finder patterns.

How to use this generator
Pick QR or barcode
Use the top toggles to choose QR codes or barcodes. QR is best for links, contact info, and WiFi; barcodes suit SKUs and inventory when you need linear symbologies.
Choose the input type
For QR, select text, URL, email, phone, or WiFi, then enter your content. Double-check URLs and WiFi passwords before downloading—what you encode is what scanners will use.
Tune appearance
Adjust size, colors, error correction, and optional logo. Prefer strong contrast for production prints; use transparent backgrounds only when your layout truly needs it.
Preview and download
Confirm the preview, then download PNG for raster use or SVG for vector workflows. Test a printed sample before large runs—especially for small codes or glossy finishes.

How It Works
Creating QR codes and barcodes with our free generator is simple and straightforward. Follow these easy steps to generate professional codes in seconds, with no technical knowledge required.
1
Choose Type
Select the type of data you want to encode: Text for plain information, URL for website links, Email for contact addresses, Phone for phone numbers, or WiFi for network credentials. Each type has specific formatting to ensure compatibility with scanning apps.
2
Enter Data
Input the information you want to encode into the QR code. For URLs, you can include or omit the https:// prefix. For WiFi codes, enter your network name (SSID), password, and security type. The generator will automatically format the data correctly.
3
Customize
Personalize your QR code by adjusting the size (100-500 pixels), choosing custom foreground and background colors, setting error correction levels for durability, and optionally adding your logo in the center. You can also enable transparent backgrounds for design flexibility.
4
Download
Save your generated QR code or barcode instantly in PNG format for web and social media use, or SVG format for high-quality printing and scalable graphics. Both formats are ready to use immediately with no watermarks or limitations.
Additional Tips for Best Results
- •Test your QR code with multiple scanning apps to ensure compatibility across different devices
- •Use higher error correction levels if your QR code will be printed or displayed in challenging conditions
- •Keep logo sizes moderate (under 30% of code area) to maintain scannability
- •Choose appropriate sizes based on your use case - larger for print, smaller for digital displays

What Are QR Codes and How Do They Work?
QR codes (Quick Response codes) are two-dimensional barcodes that can store various types of information, including text, URLs, contact details, WiFi credentials, and more. They were first developed in 1994 by Denso Wave, a Japanese automotive company, and have since become ubiquitous in modern digital communication.
When you scan a QR code with a smartphone camera or QR code reader app, the encoded information is instantly decoded and displayed or executed. This makes QR codes an efficient way to bridge the gap between physical and digital worlds, allowing users to quickly access websites, share contact information, connect to WiFi networks, or retrieve any stored data with a simple scan.
Our QR code generator uses advanced error correction algorithms to ensure your codes remain scannable even if partially damaged or obscured. You can customize the appearance, add logos, and choose from multiple error correction levels to balance between data capacity and reliability. Learn more about QR codes in our blog.
Common Uses for QR Codes
QR codes have become essential tools in various industries and everyday applications. Here are some of the most popular use cases:
- Website Links: Quickly direct users to your website, landing pages, or online content without typing URLs
- Contact Information: Share vCard data including name, phone, email, and address for easy contact saving
- WiFi Network Sharing: Generate QR codes that allow guests to connect to your WiFi network automatically
- Email and Phone: Create codes that open email clients or dial phone numbers with pre-filled information
- Marketing and Advertising: Use QR codes in print materials, billboards, and packaging to drive online engagement
- Event Management: Provide quick access to event details, tickets, or registration forms
- Restaurant Menus: Offer contactless menu access, especially popular in the post-pandemic era
- Product Information: Link physical products to online content, reviews, or purchase pages
The versatility of QR codes makes them valuable for businesses, educators, event organizers, and individuals looking to share information efficiently and securely. Check out our about page to learn more about our tool and its features.
Benefits of Using Our QR Code Generator
100% Free and No Registration Required
Unlike many QR code generators that require accounts or subscriptions, our tool is completely free to use. You can generate unlimited QR codes and barcodes without any restrictions, hidden fees, or signup requirements. This makes it perfect for quick tasks, testing, or regular use.
Complete Privacy and Security
All QR code generation happens entirely in your browser using client-side JavaScript. This means your data never leaves your device - we don't store, log, or transmit any of your information to our servers. Whether you're encoding sensitive WiFi passwords, personal contact details, or confidential URLs, your privacy is guaranteed.
Full Customization Options
Customize your QR codes to match your brand or design preferences. Adjust the size from 100px to 500px, choose custom foreground and background colors, set error correction levels for better durability, and even add your logo to the center. You can also opt for transparent backgrounds for seamless integration into designs.
Multiple Output Formats
Download your QR codes in PNG format for web use, social media, or general sharing. For professional printing, design work, or when you need scalable graphics, choose SVG format which maintains perfect quality at any size. Both formats are generated instantly and ready to use.
Barcode Generation Included
In addition to QR codes, our tool supports multiple barcode formats including CODE128, EAN13, UPC, and CODE39. This makes it a comprehensive solution for inventory management, retail, shipping, and any application requiring traditional barcode functionality.
When to Use QR Codes vs Barcodes
Our tool creates both QR codes and barcodes. Use QR codes when you need to link to websites, share contact or WiFi details, or store more than a short identifier. Use barcodes when you need product or item identification (e.g. UPC, EAN, CODE128) for retail, inventory, or shipping. QR codes are scanned with any smartphone camera; traditional barcodes are often read with dedicated scanners. For a full comparison, see our guide on QR code vs barcode. For printing tips so your codes scan reliably, check our size and DPI guide.
