Free Online QR Code Generator
QR codes bridge the physical and digital worlds. A quick scan with any smartphone camera opens a website, connects to WiFi, shares contact details, or triggers a payment — no typing required. Our free QR code generator creates fully customizable codes from URLs, plain text, WiFi credentials, email addresses, and phone numbers. Set the size, choose error correction level, pick custom foreground and background colors, and download as PNG or SVG.
Unlike many QR generators that add watermarks or require accounts, this tool produces clean, production-ready codes with no branding. Everything generates instantly in your browser as you type — no server round-trips, no data collection, and no limits on how many codes you create. Use it for restaurant menus, event tickets, product packaging, business cards, WiFi sharing, and any scenario where you need a scannable link between the physical and digital world.
How to Use the QR Code Generator
Enter your content in the text area — a URL, WiFi string, email, phone number, or any plain text. The QR code renders live as you type. Choose a size from 128×128 to 1024×1024 pixels. Select an error correction level: L (7%), M (15%), Q (25%), or H (30%). Pick foreground and background colors that match your brand. Switch between PNG for fixed-pixel digital use and SVG for scalable print output. Download the file or copy the output to your clipboard. Test the code with your phone before deploying it in production.

Tips for Creating Scannable QR Codes
Keep URLs under 100 characters when possible — shorter content produces smaller, easier-to-scan codes. Ensure strong contrast between foreground and background colors; avoid light-on-light or dark-on-dark combinations. Use error correction level M (15%) for most digital uses and H (30%) if you plan to overlay a logo on the code. Print codes at a minimum of 2×2 cm for reliable scanning. Always test with multiple devices and camera apps before printing hundreds of copies. For WiFi codes, use the format SSID:NetworkName;T:WPA;P:Password;; and verify the connection works on both iOS and Android before distributing printed materials. Consider using a URL shortener before encoding long URLs to produce smaller, more scannable QR codes. Test generated codes in both bright and dim lighting conditions, as poor lighting is the most common cause of failed scans in real-world deployments.
Frequently Asked Questions
Do QR codes expire?
Static QR codes generated by this tool never expire. The encoded data is permanent. However, if the URL you encoded becomes inactive, the code will still scan but lead to a dead page. Use short redirect URLs if you need to change the destination later.
How much data can a QR code hold?
Up to 4,296 alphanumeric characters or 7,089 numeric characters depending on error correction level. Shorter content produces smaller codes that are faster and easier to scan.
What error correction level should I use?
M (15%) works for most digital uses like websites and apps. Use H (30%) if you plan to place a logo or graphic over the center of the code, as higher correction tolerates more obscured data modules.
Can I use custom brand colors?
Yes. Pick any foreground and background color using the color pickers. Ensure strong contrast for reliable scanning — dark foreground on light background works best. Avoid similar shades that reduce scannability.
Should I download PNG or SVG?
PNG is ideal for digital use at a specific pixel size — social media, websites, and apps. SVG is vector-based and scales infinitely, making it the better choice for print materials like business cards, posters, and signage.
Are QR codes free to use commercially?
Yes. The QR code standard is open and license-free. You can use generated codes for any personal or commercial purpose without royalties or attribution.
Can I encode a vCard or contact card?
Yes. Paste vCard text (BEGIN:VCARD...END:VCARD) directly into the input field. Scanning the resulting QR code will prompt the user to save the contact on their phone. Keep the vCard data concise for reliable scanning.
