QR Code Generator
Create a custom QR code for text or links and download it as a PNG for free. Everything is generated privately in your browser.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
How to create a QR code
- Enter the website address or text to encode.
- Choose a size and high-contrast colors.
- Generate, scan-test, and download the PNG.
The generator converts text into a two-dimensional matrix with error-correction data, quiet-zone margins, and finder patterns that scanners use to locate and decode the content. Medium error correction balances resilience with capacity.
FAQ
What can I put in a QR code?
You can encode a website address, plain text, email address, phone number, or any other short text that a scanner can interpret.
Is my QR code content uploaded?
No. The QR image is generated by code running in your browser; the entered content is not sent to Online Tool Store.
Which image size should I choose?
512 pixels works well for most screens and documents. Choose 1024 pixels for larger print layouts, and test the final printed code before distributing it.
Why does color contrast matter?
QR scanners distinguish dark modules from the background. Strong contrast improves reliability, so the tool rejects color pairs that are too similar.
Can I edit a QR code after downloading it?
The PNG pixels can be edited, but changing modules may make the code unreadable. It is safer to change the source text or colors here and generate a new image.
