QR Code Generator

Generate QR codes for URLs, text, Wi-Fi, and contact details

The QR Code Generator turns URLs, text, Wi-Fi details, and contact information into scannable QR codes that you can download as PNG or copy straight from the browser. You control the colors and output size, and the code is drawn locally on a canvas so the encoded content never leaves your device.

How to Use

Choose the QR type such as URL, text, email, phone, Wi-Fi, or vCard
Fill in the fields for that type
Set the foreground color, background color, and output size
Click "Generate QR Code" and then download the PNG or copy it to the clipboard

Features

URL, text, email, phone, Wi-Fi, and basic vCard support
Custom foreground and background colors
128px, 256px, and 512px output sizes
PNG download plus clipboard copy
Local canvas rendering in the browser

Tips for getting QR Code Generator right

Keep the encoded content short — less data makes a simpler code that scans faster
Test the code with a different phone app than the one you usually use
Use the 512px option for print or signage where the code will appear larger
Stick to dark-on-light color combinations unless you have already tested a branded palette

Worked example: WiFi QR code

Choose the WiFi type and enter network name MyHomeWiFi, password correct-horse-42, and encryption WPA. Generate the code, download it as PNG, and print it near your router so guests can scan and join without you reading the password aloud.

How to keep a QR code easy to scan

Keep the encoded content short whenever possible so the code stays less dense
Use dark foreground colors on a light background for the best contrast
Choose a larger output size for print or for codes that will be scanned from farther away
Test the finished code with at least one other phone before you distribute it widely

Real-World Use Cases

Creating QR codes for WiFi network sharing
Building QR codes for business cards and contact info
Adding scannable links to posters, menus, or packaging
Creating plain-text or phone-call codes for printed materials
Generating quick-feedback or signup links for events

Best Practices

Keep QR codes simple — less data means faster scanning
Ensure high contrast between the code and background colors
Test the QR code with at least two different phones
Choose the larger output size for print materials
Use a short landing URL when the final code will be scanned from a distance

Common Mistakes to Avoid

Using too much data in a single QR code and making it dense
Choosing colors that reduce contrast and scannability
Making the QR code too small for the scanning distance
Not testing the QR code before printing or publishing it
Forgetting that the built-in vCard is intentionally simple

Troubleshooting

If the QR code won't scan, increase the size or improve contrast
For printed codes, test at the actual print size before mass printing
If colors make it unreadable, switch to standard black and white
Reduce the amount of encoded data if scanning is unreliable
Re-generate the code after checking for typos in the entered fields

Frequently Asked Questions

What content types can I encode?

URLs, plain text, email addresses, phone numbers, Wi-Fi credentials, and a simple vCard with first and last name.

Can I add a logo or export SVG?

No. The current tool renders a clean QR code to a canvas and lets you download it as PNG or copy the image to your clipboard.

Will the QR code still scan after customization?

Usually yes, as long as you keep strong contrast between the dark modules and the background and do not make the code too small.

Privacy & Security

QR code generation happens in your browser. The encoded data is not transmitted to any server. The generated image is created locally using the Canvas API.
