How to Use This QR Code Generator
- Select a QR code typeChoose from URL, plain text, WiFi network, vCard contact, or email. Each type has its own input fields tailored to the data format.
- Enter your dataFor a URL code, simply paste your web address into the input field. For WiFi, enter your network name (SSID), password, and encryption type. For vCard, fill in the contact details you want to share.
- Customize colors and add a logoOnce your data is entered, the QR code generates automatically in real time. You can customize the appearance by changing the foreground and background colors using the color pickers. To add a logo or brand image, click the logo upload area and select an image from your device - it will appear centered on the QR code.
- Download as PNG or SVGWhen you're satisfied with the result, click the download button and choose your preferred format: PNG for general use or SVG for scalable, print-quality output.
The QR code is generated entirely in your browser - no data is sent to any server, and nothing is stored.

What is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode that stores information in a pattern of black and white squares. Originally invented in 1994 by Denso Wave for tracking automotive parts, QR codes have become one of the most widely used data-sharing tools in the world. A modern QR code generator lets anyone turn a URL, WiFi password, or contact card into a scannable graphic in seconds.
What kinds of data QR codes store
QR codes can store various types of data including website URLs, plain text, contact information (vCard), WiFi credentials, email addresses, SMS messages, and more. When scanned with a smartphone camera or QR reader app, the encoded data is instantly decoded and acted upon — opening a webpage, connecting to WiFi, saving a contact, or composing a message.
How error correction keeps codes readable
The technology works by encoding data into a grid pattern using error correction algorithms. This means QR codes can still be read even if partially damaged or obscured. Most QR codes use Reed-Solomon error correction, which can recover up to 30% of lost data depending on the error correction level chosen (L, M, Q, or H).
Universal smartphone support
Modern smartphones with iOS and Android can scan QR codes directly through their built-in camera apps — no separate app is needed. This universal compatibility has made QR codes essential for businesses, marketing, event management, contactless payments, and personal use.
QR code versions and capacity
QR codes come in different versions ranging from Version 1 (21×21 modules) to Version 40 (177×177 modules), with larger versions capable of storing more data. For most use cases like URLs and contact cards, smaller versions are sufficient.
Types of QR Codes You Can Create
- URL QR codeLink to a website, landing page, menu, or app store listing. The most common type.
- WiFi QR codeShare network name, password, and encryption (WPA/WPA2/WPA3) with guests. One scan connects them automatically.
- vCard QR codeEncode a full contact card (name, phone, email, title, website, address) so scanning saves it directly to the address book.
- Email QR codePre-fill an email with subject and body, perfect for contact forms on printed materials.
- Plain text QR codeAny arbitrary text, from event codes to recipe instructions.
- SMS / phone QR codeDial a number or send a pre-filled text message with one scan.

QR Code Design & Print Tips
- Keep contrast highDark on light is easiest for phone cameras. Reverse-color codes can fail.
- Leave a quiet zoneKeep at least 4 modules of empty space around the code. Don't crowd it with text.
- Size for distanceMinimum QR code size is roughly scanning distance ÷ 10. Posters need larger codes than business cards.
- Use SVG for printSVG keeps edges sharp at any resolution; PNG may blur when scaled up.
- Shorten long URLsShorter data = simpler, more scannable codes. Use a URL shortener before generating.
- Test before you shipScan from 2–3 different phones and angles before printing thousands of copies.
- Add a call to actionPrint "Scan to connect" or "Scan for menu" next to the code so viewers know what to expect.
Frequently Asked Questions
Yes, completely free with no limits on how many QR codes you can create. There's no sign-up, no watermark, and no restrictions. Generate as many codes as you need.
Yes. Upload any image file (PNG, JPG, SVG) and it will be placed in the center of your QR code. The error correction ensures the code remains scannable even with a logo overlay.
PNG is a standard image format suitable for digital use - sharing online, presentations, or documents. SVG is a vector format that scales to any size without losing quality, making it ideal for print materials like business cards, posters, and flyers.
No. QR codes generated here are static - they encode data directly and never expire. As long as the content they point to (like a URL) remains active, the QR code will work forever.
Absolutely. Everything is processed locally in your browser. Your data never leaves your device - nothing is uploaded, stored, or logged on any server.
Choose the WiFi type, enter your SSID (network name), password, and encryption (WPA/WPA2/WPA3 or none for open networks). The QR code is generated instantly. Print it and tape it next to the router — any modern iPhone or Android connects automatically after a single scan.
Select vCard, fill in name, company, job title, phone, email, website, and address. The QR code encodes a standard vCard 3.0 string so that any smartphone camera saves the contact directly to the address book when scanned.
Yes. QR codes include Reed-Solomon error correction that can recover up to 30% of the pattern at the highest level (H). The generator centers the logo in a small square so the finder patterns and data zones around it remain intact. Always test the printed code with a phone before a large print run.
Rule of thumb: the QR code should be at least 1/10 of the scanning distance. For a business card scanned at 10 inches, 1 inch square is enough. For a poster read from 10 feet away, print at least 12 inches square. Download the SVG for crisp print quality at any size.
The maximum capacity is roughly 4,296 alphanumeric characters or 2,953 bytes (Version 40 with lowest error correction). For scannability keep URL codes under 200 characters — shorter links produce simpler, more reliable QR codes.
Yes — pick any foreground and background color that match your brand. For scannability, keep high contrast (ideally dark foreground on a light background) and avoid colors that are too close in brightness.
Yes. QR codes you create here are yours to use on marketing materials, menus, packaging, posters, and products — no attribution required, no royalties, no expiration.
