Acerca de la herramienta Generador de códigos QR
The QR code generator creates a scannable code from whatever you enter - a website URL, plain text, a phone number or contact details - and gives you a sharp image to download and use anywhere: menus, flyers, posters, product packaging, business cards, event signage. The codes are static, which means the content is encoded directly in the pattern: they never expire, need no account, and keep working forever regardless of this website - unlike "dynamic" QR services that route scans through their servers and can put your code behind a subscription later. For print, download the image at a comfortable size and keep a quiet margin around it; codes as small as 2×2 cm scan reliably when printed cleanly.

Preguntas frecuentes
Do these QR codes expire?
No. The generator makes static QR codes - the URL or text is encoded directly in the pattern itself, so the code works forever and does not depend on this website or any subscription.
What can I put in a QR code?
A website URL is most common, but plain text, phone numbers and contact information work too. Keep the content short - the more data, the denser and harder to scan the code becomes.
What is the difference between static and dynamic QR codes?
Static codes (this tool) encode the content permanently in the image - free forever, but the destination cannot be changed after printing. Dynamic codes redirect through a service so the destination can be edited, but they break if the service shuts down or starts charging.
How small can I print a QR code?
Acerca de 2×2 cm (1×1 inch) is a safe minimum for close-range scanning, larger for posters scanned from a distance. Always keep a white margin (quiet zone) around the code and test-scan a printed sample.
Can I track how many people scan my code?
A static code has no built-in tracking. The standard trick: link to your URL with a query tag like ?src=qr and count those visits in your website analytics.
Is the generator free for commercial use?
Yes. Generate and print unlimited codes for business use - menus, packaging, marketing - at no cost and with no attribution required.
