Create a QR code for a website link, download it as a PNG and check the destination before sharing the code on a screen or printed material.
Prepare the complete destination address
Start with the exact page you want people to reach. Copy the complete address, including https://, from a trusted source. If the code should open a menu, product page or guide, use that page's address rather than a homepage that forces people to search again.
Read the address before generating the code. Watch for missing characters, accidental spaces and an old page path. ToolNivo encodes the content you enter; it does not visit the destination, check whether it is available or correct a mistyped domain for you.
Generate the QR preview
Open QR Code Generator and paste the link into the input box. Select Generate QR Code. The tool creates a black-on-white code locally in your browser and shows a preview with its image dimensions.
The current limit is 1,000 UTF-8 bytes. A long address with many query parameters can produce a denser pattern than a short address. Use a simpler destination when one is available, but do not remove parameters without checking whether the link still opens the intended page.
Download and test the actual image
Choose Download PNG and save the result. Test the downloaded image, not only the preview. Scan it with a phone and compare the recognized address with the destination you intended. Open it and confirm that the page is accessible to the people who will receive the code.
For example, a link that works while you are signed into a private account may still require recipients to sign in. Successful QR recognition means the address was decoded; it does not guarantee that every visitor can access the linked content.
Understand what can change afterward
This tool creates static QR codes. The original address is stored in the pattern itself, without a ToolNivo tracking redirect. You cannot replace that address inside an already downloaded image. To encode a different address, generate a new code and replace the old image wherever it is displayed.
The code has no service-controlled expiration, but the destination website can move, disappear or change its content. Keep that distinction in mind before printing a large batch. Make one sample, scan it under realistic conditions and check the destination again before wider distribution.
