QR Code Generator: Create, Test and Download a QR Code
A QR code stores data in a two-dimensional pattern that a compatible camera or scanner can read. It is often used for web links, short text, contact details and other compact information. A QR code is a way to encode data—not a guarantee that the destination is safe.
1. Choose the right content
A URL is useful when you want someone to open a website. Plain text works for short notes or instructions. Keep content concise: longer data generally creates a denser code that can be harder to scan at small sizes.
Check the full URL, including the domain and spelling. If you are making a code for print, decide where it will be used and leave enough blank margin around the code so scanners can detect its edges.
2. Download and test the result
Download a PNG for common documents and images, or use SVG where a vector format is useful and the receiving software supports it. After downloading, scan the actual saved file from another device and confirm that it opens the intended content.
Keep strong contrast between the code and its background, avoid covering the pattern with a logo, do not stretch it out of proportion, and test a printed sample at the final physical size. A QR code that works on a monitor may fail when printed too small or blurred.
3. Understand privacy when generating
Do not encode passwords, payment credentials, private documents or other sensitive information in a QR code. Anyone who can scan the code may be able to read the encoded content. A code does not encrypt the data.
The current QR generator uses an external QR-generation endpoint, so the content entered for generation is sent to that service to create the image. Do not enter confidential or sensitive information. Use a trusted, privacy-reviewed generator if the content must remain private.
4. Scan with care
Attackers can place a malicious QR code over a legitimate one or use a code to send people to a deceptive login page. Preview the destination when your camera allows it, inspect the domain, and do not enter credentials just because a QR code asks you to.
Treat a QR code like an unfamiliar link. If it appears on a payment notice, parcel, poster or public surface unexpectedly, verify it through the organisation’s official channel before acting.
Frequently asked questions
Does a QR code make a link safe?
No. It only encodes information. The destination may be legitimate or malicious, so inspect and verify links before opening them.
Should I use PNG or SVG?
PNG is widely supported and convenient for typical sharing. SVG can scale cleanly for supported design and print workflows. Always test the exported file in the software and scanner you plan to use.
Can I encode private information?
Avoid it. QR codes do not encrypt their contents, and this site’s generator sends entered content to an external service to create the code.
