General information only
Our guides offer general, practical information about QR codes, barcodes and related topics. They aren't legal, financial, security or professional advice for your specific situation. Standards, platform features and regulations change; check primary sources, which we link to, before making important decisions.
The scan test
Our generator renders each code and reads it back with an open-source decoder. A passing result is a strong sign the design is readable, but it's not a guarantee: real-world scanning depends on printing, materials, size, lighting, distance and the device. Always test a printed proof with several phones before producing materials in quantity.
Content of codes
We don't see, review or host the content people encode. A QR code made with our tools is the responsibility of whoever made and published it. If you encounter a harmful code, see Report abuse.
Scanner safety checks
Our scanners point out common warning signs in links, such as unencrypted addresses or look-alike domains. These are aids, not a security product, and a link without warnings can still be harmful. Use your own judgement before opening links or entering information.
External links
We link to other websites for reference. We don't control them and aren't responsible for their content, availability or privacy practices.
