QR codes (Quick Response codes) are two-dimensional barcodes that can store various types of data. They're widely used for marketing, payments, contact sharing, and product information. This tool lets you generate custom QR codes for any purpose, downloadable as PNG images.

Static QR codes (the kind this tool generates) never expire. They directly encode the data. Dynamic QR codes (which redirect through a server) can expire if the service is discontinued. Always test your QR code before distributing it.
It depends on the version and error correction level. A version 40 QR code with low error correction can store up to 7,089 numeric characters or 4,296 alphanumeric characters. For URLs, aim for under 300 characters for reliable scanning.
Yes, because QR codes have error correction. You can cover up to about 30% of the QR code (using high error correction level) and it will still scan. However, always test thoroughly - different phones and apps may have different results.
Static QR codes directly encode the data and can't be changed. Dynamic QR codes point to a short URL that redirects to the actual destination, so you can change where they point without reprinting. Dynamic QR codes require a service and usually cost money.
