Do these QR codes expire?
No. Many "free" generators create dynamic codes that redirect through their servers and stop working unless you pay. Ours encode your content directly, so they work forever.
Frequently asked questions
Can I use the QR codes commercially?
Yes, on menus, packaging, flyers, business cards, anywhere. No attribution required.
PNG or SVG?
Use PNG for screens and documents. Use SVG for print, because it scales to any size without blurring.
What is error correction?
Higher levels let the code scan even if part of it is damaged or covered by a logo, at the cost of a denser pattern.
