Gratis QR Code Generator — Create Scannable Codes, Descargar PNG

Create custom QR codes instantly with our free QR Code Generator on XConverters. Enter any text or URL, adjust size, preview the code, and download a clean PNG — generated locally en tu navegador with the qrcode library. No watermark, no account, completamente gratis.

Qué hace esta herramienta

QR codes bridge physical and digital experiences — menus, event check-in, Wi-Fi sharing, product packaging, and business cards all use scannable squares to open links or pass data. A reliable generator produces sharp, high-contrast codes that phone cameras read quickly without proprietary apps.

XConverters renders QR codes entirely en tu navegador using the qrcode library. Type or paste your payload — a website URL, plain text, phone number, or custom string — and set the pixel size for the output image. A live preview updates as you edit so you can verify readability before download. The exported PNG has no watermark and is yours to use commercially or personally.

Because generation is local, marketing campaigns, internal event links, and confidential URLs never pass through our servers. There is sin registro and no limit on how many codes you create. Descargar filenames use a sensible default so you can organize assets quickly.

Higher size values produce denser pixel grids suitable for print posters and stickers; smaller sizes work for screen-only use. Always test-scan the preview on iOS and Android before mass printing.
