Create a QR code that scans: links, borders and print checks
A QR code needs to work in the place where people will use it. Test the encoded content, keep its clear border, and scan the saved image at its final display or print size.
Encode the content people should actually open
Open the QR Code Generator and choose Website URL, Plain text or Wi-Fi network. For a link, use a complete HTTP or HTTPS address and open that address yourself before encoding it. Check the path as well as the domain.
For example, a code for a menu should point to the page guests can open, not an administrator editing page. A short direct link is easier to fit than a long message. Unicode characters can use several UTF-8 bytes each; the tool checks byte limits and QR capacity.
These are static codes. The image contains fixed content without a subscription redirect. If you need a different URL later, create a new code. A stable URL can continue to serve updated content on a website you control, but the encoded address itself does not change.
Keep contrast and the clear border
Start with a dark foreground and the supplied white background. Keep the clear border intact when placing the code in a design. Avoid cropping, blur, stretched dimensions or decoration that covers the squares.
Error correction can help a code tolerate some damage, but higher settings may make the pattern denser. It is not a substitute for a clear image. Test the content and styling together instead of choosing the highest setting automatically.
A useful first test
Create a code for https://example.com, download it, and scan the saved file from another screen. Replace the sample URL with your real destination, regenerate, and repeat the test.
Choose an export and test the final size
PNG works in ordinary documents and image editors. SVG scales for print layouts without introducing image-resize blur. Both contain the same encoded content. The PNG target size is rounded to whole module pixels; read the actual output dimensions below the preview.
- Download the code and insert it into the intended design.
- Scan the final layout with the device your visitors are likely to use.
- For print, make a sample at the intended physical size and check it under ordinary lighting.
- Confirm that the scanned destination is correct and still accessible.
There is no universal minimum print size that works for every message, camera and viewing distance. A code that scans on your large monitor can fail when reduced onto a small label.
Treat Wi-Fi QR images as credentials
A Wi-Fi code contains the network details, including its password when provided. Anyone with a compatible scanner can read them. Share the image only with people who should have access and regenerate it when credentials change.
The tool offers WPA/WPA2 Personal, WEP and open-network presets with a hidden-network option. WPA3 and enterprise authentication are not covered. Device support varies, so test joining with the intended phone rather than assuming every scanner interprets the payload identically.
Questions & answers
Do static QR codes expire?
The image has no built-in expiration. A website can go offline or change access rules, and Wi-Fi credentials can change.
Can I edit the code after printing it?
The encoded content is fixed. You need a new image to change it. Content at a stable website address can be updated separately.
Why does my PNG have a different size than selected?
The tool uses whole pixels per QR module to keep edges sharp. The selected size is a target; the exact output dimensions are shown below the preview.
What should I try when a code does not scan?
Shorten the content, keep the white border, avoid blur and cropping, and enlarge the final image. Test the saved output on the intended device.
