QR Code Generator
Create a QR code for a link, text, Wi-Fi network, or contact card. Free, instant, no sign-up.
Error Correction Level
Higher levels stay scannable even if the code is partly damaged or covered by a logo, at the cost of a slightly denser pattern.
Fill in the details above to generate your QR code
A QR code is a two-dimensional barcode that stores data — a website link, plain text, Wi-Fi credentials, or a contact card — in a pattern that any modern phone camera can scan and decode in under a second. Unlike a traditional barcode, which only reads left to right, a QR code encodes data in both dimensions, which is what lets it pack in far more information within the same physical space.
This generator builds the code entirely in your browser using the same open QR encoding standard used everywhere else — there's no server involved in creating it, no account required, and no tracking layer inserted between you and the person who eventually scans it. Once generated, the code is just an image; it doesn't phone home or expire.
Four common formats are supported: a plain URL for linking to a website or page, free-form text for anything else, a Wi-Fi network profile that lets a phone join automatically without typing a password, and a contact card (vCard) that a phone can save directly into its address book when scanned.
The 'error correction' setting controls how much of the code's pattern can be damaged, obscured, or covered by a logo while still scanning correctly — higher levels rebuild more of the missing data at scan time, at the cost of a visually denser code. For a code that will be printed small or placed somewhere it might get scuffed, a higher level adds real reliability.
Step-by-step instructions
- 1
Choose a code type
Pick URL, Text, Wi-Fi, or Contact depending on what you want the code to do when scanned.
- 2
Fill in the details
Enter your link, message, network credentials, or contact info in the fields shown.
- 3
Set the error correction level
Higher levels stay scannable even if the code gets partly covered or damaged, useful for printed codes.
- 4
Download your code
Save as PNG for general use, or SVG if you need to scale it up for print without losing sharpness.
Common use cases
Linking a printed flyer to a website
Add a scannable code to posters, business cards, or packaging that opens a URL instantly.
Sharing Wi-Fi access without reading out a password
Generate a code guests can scan to join your network automatically, no typing required.
Digital business cards
Create a contact QR code that saves your name, phone, and email directly into someone's phone when scanned.
Restaurant and event menus
Point a table tent or poster at a digital menu or event page without printing a long URL.
Quick device-to-device text transfer
Encode a short message or code as a QR code to transfer it to another device by scanning instead of typing.
Tips for best results
- Test any code you plan to print by scanning it on a couple of different phones first — some older camera apps handle certain error-correction levels or code sizes better than others.
- Use High error correction if you plan to add a logo to the center of the code, since that area of the pattern gets covered.
- Keep printed codes at least 2×2cm — very small codes are harder for phone cameras to focus on and decode reliably.
- For a Wi-Fi code, double-check the network name and password before generating — an incorrect password produces a code that looks fine but fails to connect.
- SVG downloads scale to any size without pixelation, which matters more than PNG once a code is being printed larger than a business card.
Frequently asked questions
Do QR codes expire?
No — a QR code generated this way is a static image encoding your data directly. It doesn't expire or depend on any server staying online.
Is my data uploaded anywhere when I generate a code?
No, the code is generated entirely in your browser using JavaScript. Nothing you type is sent to a server.
What's the difference between PNG and SVG downloads?
PNG is a fixed-resolution image, fine for screens and most printing. SVG is vector-based and stays perfectly sharp at any size, which matters if you're printing the code large.
Can I put a logo in the middle of my QR code?
Many scanners tolerate a small logo covering the center if you use a higher error correction level (Q or H), since that data can be reconstructed from the surrounding pattern.
Why did my Wi-Fi QR code fail to connect a phone?
Double-check the exact network name and password were entered correctly — a QR code can't validate credentials, it only encodes whatever text you provide.
Will a QR code work if it's scanned from a screen instead of printed?
Yes, as long as there's enough contrast and the screen isn't reflecting glare into the camera.
What's the maximum amount of text I can encode?
QR codes can hold up to a few thousand characters of text, though very long text produces a visually dense code that's harder to scan reliably — shorter payloads like URLs work best.
