FAQ About QR Code Generator
Is there a scan limit?
No. A QR code is static data — it works forever and can be scanned unlimited times.
Can I add my company logo?
Yes! Upload a small square logo (PNG or JPG). It will be centered inside the QR code. Make sure error correction is set to Medium or High so the logo doesn't break scanning.
What size should I use?
For print, 300×300 px or larger is recommended. For screen display, 200×200 px is sufficient. Always test scanning with your target device before mass printing.
