Ejemplos resueltos
QR code for a link
https://valtrinity.com typed into the text box, with the download set to PNG
A square QR code image that scans to https://valtrinity.com, which you can download as a PNG file for a leaflet or poster.
The code stores the address itself rather than a redirect, so it keeps working as long as the link stays live.
Code for a menu note
Text "Table 4 specials: soup of the day and the lemon tart" entered directly
A static QR code that, when scanned, shows the text "Table 4 specials: soup of the day and the lemon tart" with no link involved.
Longer text makes a denser code, so keep notes short if the code will be printed small.
Sobre QR Code Generator
A QR code turns a link, phone number, Wi-Fi detail or short message into a square pattern that a phone camera can read. This QR code generator accepts any text you enter, so you can create a code for a web address, a contact card or a note. Menus, business cards and event posters often carry them, letting people open a page without typing a long address.
You can adjust the size, error correction level and colours before you download the PNG. Error correction sets how much of the code can be damaged or obscured and still scan. Higher levels tolerate more damage but create a denser pattern that needs more room to print clearly. Keep the dark colour well contrasted against a light background so scanners can read it.

Preguntas frecuentes
How do I make a QR code from a link?
Paste the full web address into the input box, including https://, so the code points to the exact page. Set the size and error correction level you need, then download the result as a PNG. Before printing, scan the code with a phone camera to confirm it opens the correct page.
What does error correction mean in a QR code?
Error correction adds redundant data so a QR code can still be read when part of it is smudged, scratched or covered. The higher the level, the more damage it tolerates. The trade-off is that a higher level makes the pattern denser, so it needs a larger print size to scan reliably. For clean indoor use, a lower level is often enough.
What size should a QR code be for printing?
Choose a size that fits the space, and make the code larger when people will scan from further away. A common guide is a scanning distance of roughly ten times the code width. Test the printed version with a phone camera at the distance people will use, because print quality, lighting and paper finish all affect how easily it scans.
Can I change the colours of a QR code?
Yes, you can set both the foreground and background colours. Keep the code dark on a light background, because scanners read contrast more reliably that way. Inverted or very low-contrast colours can fail on some phone cameras, so test any new colour scheme before printing or publishing it.
What happens if the link in my QR code changes?
The code stores the exact text you entered, so it always points to that same address. If the page moves, the code will open the old address and needs to be generated again with the new link. Print the code only after you have confirmed the final URL, and check that it opens the right page on a phone.
