Генератор QR-кода — Бесплатно Онлайн

A standard QR code can encode up to 4,296 alphanumeric characters. In practice, shorter URLs (under 100 characters) produce simpler, faster-scanning QR codes. Very long URLs or text generate dense codes that some older scanners struggle to read.

PNG is a raster image — ideal for digital sharing, emails, and screens. SVG is a vector format that scales without pixelation, making it the right choice for print materials like business cards, posters, and packaging.

The generator produces standard black-on-white QR codes optimised for maximum scanner compatibility. Custom colors are possible in design software after export — ensure at least 70% contrast between the dark and light modules to maintain scanability.

QR codes generated here do not expire — they are static and encode the data directly. However, if the URL you encoded goes offline or changes, the QR code will scan correctly but lead nowhere. Dynamic QR code services let you update the destination URL without reprinting.

Scan the generated QR code with your phone's camera or a QR reader app before downloading or printing. Test on multiple devices if the code will appear on high-volume print materials. Ensure the destination URL is live and correct.
