No sign-up. No subscription. Never expires.
How to Generate a QR Code
1. Pick your type & enter details
Start by choosing what you want to share from the menu on the right—whether that's a simple website link, your home Wi-Fi credentials, a complete vCard contact card, or a crypto wallet. Then just paste or type your information into the fields. The preview in the middle updates instantly with every keystroke.
2. Style the dots, colors & logo
Open up Design & Styling Options if you want something beyond basic black squares. You can switch between classic squares, rounded dots, or diamonds. Pick any two colors to create a subtle linear or radial gradient, or keep it high-contrast monochrome. You can also upload your own company or personal logo right into the center—just remember to use a higher error correction tier so the code stays easy to scan.
3. Download in PNG or Vector SVG
Choose your target resolution and click Download PNG for digital use or standard printing. If you're handing this over to a professional print shop for merchandise, packaging, or big outdoor signs, grab the Vector SVG instead—vector files never lose sharpness, no matter how huge you print them.
Why Use This Generator
Permanent codes that never break
Most commercial QR generators pull a classic bait-and-switch: they route your scans through their own redirect servers, wait for you to print hundreds of flyers, and then deactivate your code after 14 days unless you pay a steep monthly subscription. We never do that. Every QR code created here encodes your actual destination directly into the raw pixel matrix. There's no middleman server and no expiration date—your code works for as long as the printed image exists.
Exported for any real-world scale
From a 3 cm sticker on a coffee pouch to a 10-meter banner over an expo booth, you get clean, precise geometry. Download raster files up to 4096px Ultra HD, or download pure Vector SVG files with zero bloat. We also calculate the minimum recommended print size in real time based on your content length, so you never end up with an unreadable print run.
Thoughtful, scannable styling
You don't need a cookie-cutter code. Customize inner data modules, corner eyes, dual-color gradients, and brand emblems without guessing whether it will scan. The built-in Reed-Solomon selector lets you bump redundancy up to 30%, keeping your codes fast and forgiving even when scanned under dim lighting, odd angles, or through scratched phone lenses.
Completely private with zero tracking
We don't believe in collecting user data behind your back. We don't save what you type into our fields, we don't store your Wi-Fi passwords, and we don't drop tracking pixels into your links. When someone points their phone at your QR code, their browser goes straight to where you pointed it, with nothing in between.
Supported QR Code Types
Websites & Social Media
The everyday standard. Route people directly to your website, landing page, portfolio, restaurant menu, YouTube channel, or booking portal. Just paste the full link, and anyone scanning with their phone camera opens your page with a single tap.
Wi-Fi Networks
Stop writing complicated Wi-Fi passwords on scraps of paper or spelling them out aloud across a noisy room. Enter your network SSID and password to create a neat scannable card. Guests or customers simply point their phone and tap 'Join Network' to connect instantly without typing a character.
Digital Business Cards & Events
Share your complete vCard 3.0 profile—including your full name, phone number, email, company, title, and website—so clients can add you to their phone address book in seconds. You can also generate iCal calendar invites so people can add meetups, concerts, or workshops directly to their calendar.
Crypto Wallets & Plain Text
Eliminate costly copy-paste mistakes by generating error-free payment QR codes for Bitcoin, Ethereum, and Solana addresses. Or encode raw, unformatted text for serial numbers, offline instructions, WiFi keys, or quick notes that can be read by any scanner without an active internet connection.
Understanding QR Codes
How does a QR code actually work?
'QR' stands for Quick Response. Unlike old-school one-dimensional barcodes that only store data horizontally in lines, a QR code is a 2D matrix storing information both horizontally and vertically. The three prominent squares in the corners are positional markers (called 'finder patterns')—they let your phone's camera instantly detect the orientation, tilt, and scale of the code, so it scans just as quickly even if you hold your phone upside down or at a steep angle.
What is Reed-Solomon error correction?
Error correction is what keeps QR codes resilient. It uses a clever mathematical formula (Reed-Solomon encoding) to duplicate key parts of the data across the matrix. This means if your printed code gets scratched, crumpled, smudged, or partially blocked by a logo in the center, your phone can still reconstruct 100% of the original information. We support all four international standards: Level L (7% recovery), Level M (15% recovery, recommended for general use), Level Q (25%), and Level H (up to 30% recovery, ideal when embedding center logos).
The D/10 rule: How big should you print?
The most common printing mistake is making the code too small for people to scan comfortably. The golden formula is the D/10 ratio: your printed code width should be at least one-tenth of the distance from which someone will scan it. If a poster is viewed from 1.5 meters away, the QR code should be at least 15 cm wide. For table cards, business cards, or drink menus scanned from arm's length (about 30 to 50 cm), 3 × 3 cm to 5 × 5 cm works reliably. And always keep a clean, empty margin (the 'quiet zone') around the perimeter.
Frequently Asked Questions
What is a QR Code?
A Quick Response (QR) code is a two-dimensional barcode that can be scanned using a smartphone camera to quickly access a website, text, or other information.
Do these QR codes expire?
No! The QR codes generated here are static, meaning they do not track data and will never expire. They are yours forever.
Can I use these for commercial purposes?
Yes, our QR codes are 100% free for both personal and commercial use without any restrictions.
Why won't my QR code scan?
Ensure there is high contrast between the QR code (dark) and the background (light). Also, test the code at the size it will be printed.
