QR Code Generator
Generate QR codes for URLs, text, WiFi, vCard and more
QR Code Generator turns a URL, block of text, WiFi network, or contact card into a scannable QR code you can download and print or share digitally — no account, no expiring links, and no watermark on the output.
How to use QR Code Generator
- 1
Choose what you're encoding — URL, plain text, WiFi, or a vCard contact.
- 2
Fill in the relevant fields (link, network name/password, contact details, etc.).
- 3
Customize the color and size if needed.
- 4
Download the QR code as a PNG or SVG file.
Everything you need to know about QR codes
What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that encodes data directly into its pattern of black and white squares — a phone's camera reads the pattern and decodes it instantly, without needing to look anything up in a database. That's an important distinction: a QR code you generate here isn't a link to some third-party redirect service that could expire — it's the data itself, encoded directly.
Types of QR codes and when to use each
| Type | Use case |
|---|---|
| URL | Linking to a website, menu, or landing page |
| Plain text | Sharing a short message, address, or note |
| WiFi | Letting guests join a network without typing a password |
| vCard | Sharing a contact card that saves directly to a phone |
How QR codes stay readable even when damaged
QR codes include built-in error correction, meaning they can still scan correctly even if part of the code is smudged, torn, or has a logo placed over the center — the format was designed for exactly this kind of real-world wear. That's also why QR codes tolerate a logo overlay reasonably well, as long as it doesn't cover too much of the pattern.
Getting a QR code that actually scans reliably
- Keep strong contrast between the foreground and background color — low-contrast codes fail to scan.
- Don't shrink it too far — a QR code needs enough physical size for a camera to resolve its pattern, especially at a distance (a code on a poster needs to be bigger than one in a business card).
- Test it with an actual phone camera before printing or publishing at scale.
QR codes vs. barcodes
A traditional barcode (like the one on a product) encodes data in a single line and typically holds far less information — usually just a numeric product code. A QR code encodes data in two dimensions, holding dramatically more data (a full URL, a WiFi password, a contact card) in a similar amount of space. Use Barcode Generator instead for something that specifically needs to be a standard product barcode (EAN-13, UPC, Code 128).

Frequently Asked Questions
Do these QR codes expire?
No — the QR code encodes your data directly (or a URL you control), so it works for as long as that content or link stays valid. There's no third-party redirect service involved.
Can I customize the color or add a logo?
You can customize the color; keep enough contrast between foreground and background so scanners can still read it reliably.
What's the difference between PNG and SVG download?
PNG is a fixed-resolution image good for screens and most printing; SVG is a vector file that scales to any size (like a billboard) with no quality loss.
What's the difference between a QR code and a barcode?
A traditional barcode encodes data in one line and holds relatively little (usually just a product number); a QR code encodes data in two dimensions and can hold dramatically more — a full URL, a WiFi password, a whole contact card.
Will the QR code still scan if part of it is damaged or covered by a logo?
Usually yes — QR codes include built-in error correction specifically so they keep working with partial damage or a small logo overlay, as long as it doesn't cover too much of the pattern.
Is my data safe when using this tool?
Yes — WiFi passwords and contact details are sent to our servers only to generate the QR code and are not stored afterward.
