Free Litecoin QR Code Generator
Before you print
How big should it be?
Rule of thumb: printed width ≥ scanning distance ÷ 10. Pick the surface above and the studio sizes the code for you, then checks the printed module size against what a press can actually hold.
Questions people actually ask
Legacy addresses starting with L or M, P2SH addresses starting with 3, and bech32 addresses starting with ltc1. UseQR checks the shape before it encodes anything, so a mistyped address is caught here rather than by a failed payment.
No. The code is built entirely in your browser, no address, amount, or label ever reaches a server.
Yes, up to 8 decimal places. Leave it blank for an open-amount request the sender fills in themselves.
Never. This is a static QR code: the payment URI lives in the squares themselves, so it works forever with no dependence on UseQR.
