What you can put in a QR code
- Links: the most common case. When scanned, the phone offers to open the page: restaurant menu, website, social profile, flyer, business card, reviews.
- Text: any text, such as a discount code, an address or a message.
- Wi-Fi: network name, security type and password: guests connect by scanning, without typing anything. Perfect for holiday rentals, cafés and offices.
- Phone, email, SMS: the phone directly opens a call, a new email (with subject and text pre-filled) or a text message.
Size, colours and error correction
For print choose at least 1024 px or download the SVG, which scales infinitely without losing sharpness (ideal for designers and print shops). The code needs good contrast: dark colour on a light background, never the reverse, and always keep a white margin around it (already included). At 2 cm or more on paper it reads easily from 20-30 cm away.
Error correction lets the code be read even if partly damaged or covered: "Medium" is fine almost always; pick "Quartile" or "High" if you plan to place a logo in the centre or print on surfaces that wear out. Higher levels produce denser codes.
No expiry, no tracking
Codes created here are "static": the content is written directly into the code, so they work forever, don't depend on an external service and don't track who scans them. The flip side is that you can't change the link after printing: if you need that flexibility, point the QR code to a page of your own that you can update.
Tips before printing
- Always test the code with two or three different phones before printing it large.
- Use short links: fewer characters mean a less dense code that is easier to read.
- Write next to the code what scanning it does ("Menu", "Free Wi-Fi", "Book now").
Frequently asked questions
Do QR codes created here expire?
No. They are static codes: the content lives inside the code itself and works forever, with no subscriptions or external services.
Can I change the link after printing the code?
No, in a static code the link is fixed. If you expect to change it, point the QR code to your own web page and update that instead.
PNG or SVG?
PNG for social media, Word documents and general use; SVG for designers, print shops and large prints, because it doesn't lose quality when enlarged.
