QR Code Generator

What Is the QR Code Generator?
The QR Code Generator turns text into a scannable QR code image. You can encode a website address, plain text, an email address, a phone number, or Wi-Fi details. Anyone with a phone camera or QR scanner can then scan the code instead of typing the information.
The code itself stores the exact text you enter. It does not shorten a link, track scans, or change the destination after it is made. If the link or text changes, you need a new code.
How to Use the QR Code Generator
- Open the QR Code Generator page.
- Choose the content tab: URL, Text, Email, Phone, or WiFi.
- Enter the content, for example
https://example.comon the URL tab. - Set the size in pixels, the foreground and background colours, and the error correction level. The defaults observed were Size 256, black on white, and Medium error correction.
- Click Process. The tool shows a preview and a result message.
- Check the preview, then click Download QR to save the image.
Worked Example
Input: https://example.com on the URL tab, Size 256, black foreground, white background, Error Correction Medium.
Steps: entered the URL and clicked Process.
Observed result: the Result panel showed “QR Code Generated!” and “Content: https://example.com”, a QR code preview appeared, and a Download QR link was shown.
Conclusion: 1 input produced 1 QR image at 256 pixels square. Scanning that code should open https://example.com. Always test-scan before printing.
Limitations
- The workspace button is labelled Process, not Generate, and the download link is labelled Download QR, not Download PNG — use the labels actually shown.
- Scanning needs a phone camera with QR support or a scanner app. A code printed too small, in low contrast, or on glossy or damaged paper may not scan.
- Higher error correction helps a code survive partial damage, but it also makes the code denser. Very long content makes a denser code that is harder to scan at small sizes.
- A printed or saved QR code is fixed. If the link changes, generate a new code and replace the old one everywhere it was used.
- Do not encode passwords, secrets, or private links in a QR code that will be shared publicly. Anyone who sees the code can decode it.
Frequently Asked Questions
Do I need an app to create a QR code?
No. Enter your content, click Process, and use Download QR to save the image in your browser.
What size should I use?
Use 256 pixels for on-screen use, as in the worked example. Use a larger size for print, especially if the code will be viewed from a distance.
What does error correction do?
Error correction adds redundancy so the code can still be read if part of it is scratched, faded, or covered. Medium was the default in the test.
Can I change a QR code after printing it?
No. A printed QR code is fixed. If the link or content changes, generate a new code and replace the old one.
