QR code tips
What can I put inside a QR code?
You can encode a website address, plain text, a phone number, an email address or another short text value. Keep the content concise when possible because very large QR payloads become denser and can be harder for some cameras to scan.
Which size should I download?
Use a larger PNG when the code will be printed or placed inside a design. A smaller size is usually enough for webpages and on-screen sharing, provided the code remains sharp and has clear space around it.
